  1. ** UPDATED TO WORK WITH NEWEST DCS OPEN BETA (WITH MULTI-THREADING) ** - Better performance with hardly any shadow quality loss - Works perfect with both screens/monitors and VR - No slower loading of missions of any kind - Made for DCS 2.8 but also works with DCS 2.9 (both MT an ST, Open Beta or Stable) - Not IC compliant for Multiplayer (only with servers which allow mods!) Shadows Reduced Impact (v2.11) download: https://www.digitalcombatsimulator.com/en/files/3329503/ ______ NOTES AND DESCRIPTION __________________________________ This is a modification that alters values of shadow cascade(s) for better performance. In practice, what happens when using this mod is the terrain shadows (outside-cockpit) being drawn as far as before, but with overall performance improved with quite small visual difference trade-off. The other benefit is that, at the same time, the inside-cockpit shadows maintain high quality in all settings (4096x4096 pixel shadows, though even that can be changed if really desired). ______ INSTALLATION ______________________________________________ This mod replaces one file found in the game installation folder (same paths and structure as you see in the mod). A mod manager (such as OvGME) is recommended, because it's the quickest way to install and uninstall mods in the game. If instead you prefer to install this mod manually, there are some very simple instructions in the "READ_ME" provided with the downloaded file. After installing this mod, and for the game system options/settings to use for shadows, I suggest to put them just like in the image I attach with this mod. It's merely a suggestion, feel free to use those shadow settings as you see fit. Please remember that if updating or repairing DCS, then the SHADOWS.LUA file will be reset, and you'll need to reinstall this mod again to use it. ______ EDITING THE MOD __________________________________________ If you need to further improve performance (but at cost of shadowmap quality), you can edit the SHADOWS.LUA file with any text editor and change the size value of shadowmap. I left some notes about this subject in the "READ_ME" file. Feel free to experiment - remember to always backup your files! ______ CREDITS AND THANKS _____________________________________ - To KEGETYS for the original mod this was based on. - To the people at E.D., as there are original files modified for the purpose of this mod. ______ CHANGELOG ________________________________________________ v2.11 -- minor corrections in cascade(s) v2.0 -- changes for compatibility with DCS 2.8 OB featuring MultiThreading v1.0 -- initial release based on older Kegetys mod
  2. Hi, Just getting back into DCS. I have upgraded my pc.. nothing crazy but better than it was and wondering what the best graphics settings will be based on my specs: Ryzen 5 5600G Geforce RTX 2060 32GB Ram Monitor with 165hz M.2 NVME SSD I went into a game on high settings with DLSS enabled on balanced and was getting 100+ fps in caucasus but experienced weird freezes every 5 seconds or so.. I turned off DLSS and enabled MSAA and my fps was between 65-85. I fly the viper mainly and own Syria as well. Current graphic settings Thank you, as half the battle with DCS is getting it setup right.

    Thank you

    Just wanted to say thanks to team ED for delivering one of the best updates of the year with the introduction of DLAA/DLSS etc. I flew in VR online last night, something I rarely do in multiplayer due to the frame rate issues, and when i do i normally downtune the graphics and everything else to make it playable without stutters and freezes. Last night I forgot to do this adjustment, and it didnt care. The DLAA settings allowed smooth gameplay whilst maintaining visual fidelity, something I had to chose between before. Now it appears I don't! The new shadows are just superb, give a real depth to the environment which wasn't there before, and at times it was that good I could have said it was real. Some croppped VR screenshots. By far not the best visual quality you'll see, but for my 2080S to cope with a G2 at this grx setttings I am happy. Still going to get a 4080Ti though
  4. I started this topic to track and discuss my challenges with getting the best performance out of my system. I run DCS in windowed mode and run OBS on the side. My setup Windows 10 - latest version RTX 4090, no overclocking X570 Aorus Master Ryzen 7 5800x3D, no overclocking 64GB RAM Varjo Aero Reverb G2 v1.0. Mixed Reality: best quality, 90Hz.

(sometimes my FPS drop too low and then I would like for Reprojection to kick in). Edit 7-1-2023: Edmuss told me this does not work for DCS. So keep Reprojection OFF.
  5. The MiG-21 currently only uses a LOD0 model. It has a .lods file describing transitions but they all reference the LOD0 model and the LOD0 model has no embedded transform nodes. While the model is not the heaviest in DCS, in a multiplayer environment near a busy airfield, a few MiG-21s can add up to a lot of objects and triangles very quickly, putting an unnecessary load on the player's CPU & GPU, particularly with shadows enabled. Also, due to how the camera seems to work in DCS, zooming in can cause the 3D model to begin rendering at longer distances. I did a search in this forum for the term "lod" and saw references to different LOD levels in the past, so possibly they did exist once and have been omitted along the way. Attached are two in-game screenshots showing 10 MiG-21s taking off at Senaki airbase, at close range and 6km away, with similar object counts in both scenes. I hope you can find the time to add the lower detail LODs as it would be a great help to the multiplayer community, especially the Cold War servers.
  6. As in the title, flipping between F10 and F1 seems to have a % chance of starting long-lasting stutters and screen-tearing in VR. Usually happens after the 5th or 6th time looking at the map while on a mission. This is actually so bad that it immediately stops my gameplay, I cannot continue with it. See attached video. This bug never appeared before multithreading was introduced. https://cdn.discordapp.com/attachments/865742930064965662/1100018920297070692/20230424_200758.mp4 Oculus Quest 2 3070ti M.2 SSD for DCS 32GB memory X570 Gaming+ Ryzen 7 5800X3D
  7. My game Stuttering every 20ish seconds, and when launching missiles and explodes, in 2.8 it never happened like this. I have i7-10700 ,32GB RAM,NVIDIA 3070 8GVRAM, game on SSD. Loving DCS hope this can be heal soon. @Flappie Thank you and Hi Flappie, saw you been tracking some similar issues, hope this won't bother you. Performance monitor like: Screenshot\log\track attached. HEAVY STUTTER.trk dcs.log dcs_frame.log The performance had a big issue at the end of the Trk. If the AI play their things correctly. I got shot down by the end and all the explosions and cracking~ I can see dozens of peaks on the FPS monitor window, even when I'm Over G blacked out.
  8. Please add LODs for the 3D model to help improve performance on multiplayer servers. Fewer tris is important but also consider reducing object count in the LODs as DCS considers these when calculating lighting and shadows. This change would benefit all of the multiplayer community.
  9. The MB-339 has a beautiful 3D model but it would be helpful for performance on multiplayer servers if there were some simpler LODs added. Multiplayer in DCS is currently very hard on CPUs, especially with shadows enabled, so reducing load where possible will help all players.
  10. This issue has been reported by @NineLine but it was handled inside a report for a different issue which has now been resolved and will likely be closed in the future. I'm creating this thread to have a place to track it's progress through different Open Beta updates until it is resolved. The MiG-29 variants in DCS do not have lighter LODs. Under certain conditions the full detail model will still render at a range of more than 75km. The evidence for this issue is the .lods file for each variant and the absence of relevant .edm files in the shapes folder. This issue is still present in DCS Open Beta 2.8.2.35632
  11. It needs another rework. For the points marked as "level flight impossible", I am unsure if it is realistic or not, it is very possible the real aircraft produced enough power that full forward cyclic could not maintain level flight. However data for flight over the Vne of 125knots, let alone over 50PSI is hard to come by, and usually for the UH-1H with the old blades. Overall the huey has more available power, however at low speeds the performance discrepancy is not good. You go from requiring far too much power to requiring far too little power. However, the engine profile doesn't seem to take altitude into account. As for the engine profile itself, it is still underpowered at high power settings. The new profile produces 50PSI (1158shp) at 101% N1 The real huey produces 50PSI (1158shp) at 96-98% N1 However the EGT profile has improved significantly. The hover performance is not great, however. It requires too much power at every weight. Here is a more advanced profiling of the hover performance. The new WIP fuel consumption is far better than it was, but it's still using too much fuel at higher power settings, however it is reaching what could be considered "close enough", but could still use another tweak. The rate of climb is messed up too.
  12. There have been many reports of unexplained prolonged FPS drops in VR. I have provided what I hope is a consistent repro along with a GPU/perf capture later on below, but common symptoms of this issue seem to include: Happens randomly, but common triggers seem to be actions that cause temporary performance blips (that then turn into sustained FPS drops) FPS goes from something stable and normal (e.g. 30/45fps) to significantly lower and unplayable (e.g. 15-25fps) FPS drop lasts for many minutes, sometimes requiring exiting the game to recover VR-specific Alt-tabbing away from and back to DCS sometimes resolves the issue Returning to the main menu still exhibits abnormally low FPS I think those last three points are important, as they point to a software bug, not a hardware bottleneck. FPS would return to normal at the main menu, and alt-tabbing wouldn't fix the issue, if this were simply a problem with users' machines being incapable of sustaining adequate framerates. Furthermore, the issue seems to be VR-specific, pointing to a VR-specific bug as opposed to a hardware capacity issue. Here's a collection of forum posts that I believe exhibit this issue (there are more): The most consistent repro that I can find is to: Load into main menu Observe 90fps Load into Cold Start instant action on Marianas map in F/A-18C sim (this is a good starting point, since you're on a carrier, and can see the island in the distance) Observe stable 45fps Slowly turn your head to the left, until you're looking behind your left shoulder Slowly turn your head to face back forward, then right, until you're looking behind your right shoulder this time Turn your head back to face forward Observe ~14 fps Quit to main menu Observe ~25 fps This is on current stable Steam DCS (also on beta), Windows 10, a stock RTX 3080 (driver 512.95, doesn't seem to matter), stock Ryzen 5950x, HP Reverb G2, WMR 2000.21051.1282.0 (version doesn't seem to matter), OpenXR 110.2204.7007 (also reproduces on SteamVR), 100% render scale (3168x3096 pixels per eye), motion reprojection always on, and the following in-game settings: 2022-06-02 08:30:19.529 INFO APP: options.graphics = { ['messagesFontScale'] = 1; ['forestDetailsFactor'] = 0.75; ['rainDroplets'] = true; ['LensEffects'] = 0; ['box_mouse_cursor'] = true; ['anisotropy'] = 4; ['water'] = 1; ['motionBlur'] = 0; ['outputGamma'] = 2; ['aspect'] = 1.6666666666667; ['lights'] = 2; ['shadows'] = 4; ['MSAA'] = 1; ['SSAA'] = 0; ['civTraffic'] = ''; ['clutterMaxDistance'] = 0; ['cockpitGI'] = 0; ['terrainTextures'] = 'max'; ['multiMonitorSetup'] = '1camera'; ['shadowTree'] = false; ['chimneySmokeDensity'] = 0; ['fullScreen'] = false; ['forestDistanceFactor'] = 0.75; ['useDeferredShading'] = 1; ['DOF'] = 0; ['clouds'] = 1; ['sceneryDetailsFactor'] = 1; ['width'] = 1280; ['flatTerrainShadows'] = 0; ['visibRange'] = 'Ultra'; ['textures'] = 2; ['SSLR'] = 0; ['effects'] = 3; ['SSAO'] = 0; ['secondaryShadows'] = 0; ['sync'] = false; ['scaleGui'] = 1; ['preloadRadius'] = 150000; ['height'] = 768; ['heatBlr'] = 0; ['terrainMapMFD'] = { ['distance'] = { ['mapLodDistance3'] = 200000; ['mapLodDistance2'] = 100000; ['mapLodDistance0'] = 25000; ['mapLodDistance1'] = 50000; }; }; }; This behavior doesn't really make sense. I'm sure that the act of looking right on the Marianas map is exceeding the VRAM on my 3080, causing a temporary blip as stuff has to be paged out of VRAM for it, but when I look back forward, everything should get paged back in automatically (at least on DX11) and return to normal. And indeed, in the captures below, there isn't any persistent VRAM paging going on that would explain the severe drop in FPS. Similarly, when returning to the main menu, instead of getting 90fps like I was before, I'm at 25fps, and nothing strenuous is going on (I haven't grabbed a capture of this yet as it's much more difficult to get a capture of due to needing to alt-tab to start the capture, and alt-tab typically clears the issue in the main menu); I took a GPUView capture of the issue on the Marianas map (happy to provide to private support), and it clearly shows some kind of problem with how DCS is scheduling it's main thread. In summary, it appears to be sleeping too long and doing nothing. This isn't a problem that requires advanced multithreading, DX12, better VRAM management, etc... It simply appears to be an issue with DCS waiting too long to start rendering the next time. Here is a capture of a normal, stable 30 fps for me after loading into Marianas (higher settings than I mentioned previously, but still a decent 30fps): What I've gathered from this is that: In VR, DCS has a thread started from WinXrRuntime.dll that runs at 90Hz (or whatever the refresh rate of your headset is) You can see the row for this in the bottom left (labeled WinXrRuntime.dll) The blue boxes are when this thread is running on a CPU core. You can see a total of 14 of them, because this capture window covers about 160 milliseconds, so at 90hz we'd expect about 14 occurrences in a 160 millisecond time period I believe this is due to xrWaitFrame (https://www.khronos.org/registry/OpenXR/specs/1.0/man/html/xrWaitFrame.html), which must be called by the application to synchronize frame submissions with my headset. So this thread is probably calling xrWaitFrame on a loop to do that, which is why it's running at 90Hz The DCS.exe thread is running at 30Hz, every 3rd time that the WinXrRuntime.dll thread is running The WinXrRuntime.dll thread is seemed to be used to (among other things) schedule the main DCS.exe thread to run (i.e. this is how DCS ensures it synchronizes its frame submissions with your VR headset) You can see the row for this a bit above WinXrRuntime.dll, labeled as DCS.exe Similarly, the blue boxes are when this thread is running on a CPU core, which aligns with every 3rd time that WinXrRuntime.dll runs In this capture, when the DCS.exe thread is signaled to run, it executes for about 16ms This isn't fast enough to run at 90Hz As noted above, it's running at every 3rd time that the WinXrRuntime.dll thread is running I.e. this is running at 30Hz, or 30fps. Which with motion reprojection, is perfectly stable and playable This could run at 45Hz, however my GPU wouldn't be able to keep up, so it would be a bottleneck and my FPS wouldn't improve. You can tell this from the Device Context and RTX 3080/Hardware Queue 3D rows, which show that the GPU is being kept busy ~85% of the time. The GPU work scheduled to the Device Context queue also takes about 28ms to drain, so it's limited to about 30fps, and there's no point to the DCS.exe thread running more often (at least, not for scheduling GPU work) In summary, the main DCS.exe thread is running at the ideal 30Hz for how my hardware is performing, and I'm getting a reasonably smooth 30fps with motion reprojection Now, let's compare this with a capture of an abnormal, unstable ~22fps for me, on the same Marianas map, after briefly turning to the right and then looking forward in the same exact direction (i.e. should be rendering the same stuff as earlier in the 30fps capture): There are a few notable differences from the earlier capture that was stable at 30fps: The WinXrRuntime.dll thread is still running at the expected 90Hz The DCS.exe thread is running at 22.5Hz, every 4th time that the WinXrRuntime.dll thread is running (instead of every 3rd) In this capture, when the DCS.exe thread is signaled to run, it executes for about 23ms This is higher than in the good capture (23ms vs. 16ms) As noted above, it's running at every 4th time that the WinXrRuntime.dll thread is running I.e. this is running at 22.5Hz, or 22.5fps. Even with motion reprojection, this isn't very playable (it also varies a lot and isn't stable) This could run at 30Hz, but for some reason it isn't. My GPU isn't a bottleneck. The GPU work queued to the Device Context is still taking 28ms to drain, which is the same as the good capture. The GPU is also only being kept busy about 60% of the time, and there's no reason that the DCS.exe thread couldn't run more often (at least, probably not) In summary, the main DCS.exe thread could be running at 30Hz, and my GPU would be able to keep up, but for some reason it isn't, resulting in a very poor framerate My CPU also certainly isn't a bottleneck. I don't have an explanation as to why each frame of the DCS.exe thread went from 16ms to 23ms, but that's still fast enough to run at 30fps. I also have plenty of spare cores to which the DCS.exe thread could be scheduled to and run during this, so that isn't a problem either: In summary, it should be evident from these captures that DCS is more than capable of running this at a stable 30fps here, but isn't due to what appears to be a bug with the main DCS.exe thread literally deciding to do nothing and wait (lazy thread!). There is no CPU/GPU bottleneck. DCS must have some way of throttling how frequently the main DCS.exe thread runs. If it ran as frequently as it could, then my GPU wouldn't be able to keep up. This is why it only runs at 30Hz instead of 45Hz in the first capture, because even though it could run at 45Hz, the GPU would fall behind. So it must be doing something intelligent to throttle how often it runs. It's my theory that these framerate drops in VR (consistent with the symptoms mentioned here) are due to a bug with how the DCS main thread is scheduled to run, that causes it to run less frequently than it should in certain scenarios, and thus may be a relatively simple fix and a huge stability boost to anyone experiencing this issue (including myself). I'm happy to provide more info. I also have logs available, but I'll note that they look the same whether or not the issue is occurring, so I don't believe they'll do much good. I also have some experience in this field and would be happy to sign an NDA and look into the issue myself, but I'm sure ED has people better suited to fixing this than me. If only they're able to reproduce and look into the issue, I'm sure a lot of VR customers would be very grateful, as this issue is extremely disruptive, to the point of making the game unplayable in VR without excessive hardware purchases (like a 3090) or turning settings down to very low levels and avoiding maps like Marianas or even MP entirely.
  13. Hey, Im having a little trouble with the Sinai map, mostly around cities. With my usual settings (Image 1), I get 22fps in the middle of Cairo, with the Ka-50 III "Takeoff from helipad" mission. Turning down the settings significantly (Image 2), and loading the mission back up yields no change in performance. Nothing running except for DCS and OpenTrack, plus task manager CPU load wasnt super high, but GPU was. DCS was using a little under 10Gb of RAM, out of 32. Specs are: Ryzen 5 2600, Radeon RX 570 8Gb, 32Gb DDR4 3600Mhz RAM. Deleted FXO and Metashaders2 and renamed export.lua to export.lua.old, as there was some wierd socket stuff happening there from the DCS UFC app. Only saw a 2-3Fps improvement, but may have been a coincidence. Any ideas why Im not seeing any performance change, and what I could do to improve things?
  14. Hi, I posted a week ago in the forum and on facebook. I did get "HUH?". This forum would be a better spot. I notice a spike in the Stat for simulation. even if only flying, there is a spike in "Simulation" Trying to track down the reason. I will add a video this weekend.
  15. Hi all, What computer settings can I adjust to get the best out of the Multi-threaded version of DCS? I'm interested in things like how to allocate cores to DCS and how many for best effect, rather than just making adjustments in DCS video options. Currently running: Ryzen 9 5950X 16 core, 32 thread processor Asus Crosshair VIII Dark Hero 32Gb Viper RAM Radeon RX6700XT 4k screen w. TrackIR Thanks in advance! Goggz
  16. OK, looks stunningly beautiful but... From the FAQ: RECOMMENDED SYSTEM REQUIREMENTS (HIGH graphics preset settings): OS 64-bit Windows 8/10; DirectX11; CPU: Core i5+ at 4+ GHz or AMD FX / Ryzen; RAM: 16 GB (32 GB for heavy missions); Free hard disk space: 120 GB on Solid State Drive (SSD); Discrete video card NVIDIA GeForce GTX 1080 / AMD Radeon RX VEGA 64 or better; Joystick; requires internet activation. I am on a Windows 10, I7-10700K (5.1 GHz), 64 GB RAM (3000 MHz), RTX 3080. Also from the FAQ: Despite being an island map, you can expect similar performance to the Syria map So, Syria map gives me constant 60 FPS (consistent with my screen capability) and empty Andersen AB I get 40, Guam @ 3000 feet MSL I get 30-40, at 700 feet I get 30-40. Ocean alone at 1000 feet MSL shows as 80 fps, whereas Mediterranean sea on Syria map gives 120 fps at the same alt. I guess I need to wait for optimizations?
  17. Currently, as of DCS build 2.5.6.60645 Open Beta, we get two options for selecting our texture preferences in graphics menu:- 1. Texture - The setting which affects the textures of arcrafts and spawnable units. 2. Terrain textures - The setting that affects the textures of the terrain. My suggestion is to divide the settings further into the following categories so that people can fine tune their settings to get the optimal performance/quality balance according to their system:- 1. Aircraft Textures - Textures of your, other player's and AI aircraft. 2. Ground Unit Textures - Textures of ground units and other spawnable units like ships and aircraft carriers (If 1 and 2 aren't possible, they can be grouped together in a Spawnable Unit category) 3. Airfield Textures - Textures of the airfield including the tarmac surfaces, runways, taxiways, buildings, static objects, etc. 4. Terrain Textures - Textures of the ground APART from the airfield. I believe precious memory could be saved by doing this as people can just turn down the textures they don't want to look pretty and keep high the ones they do. For example, I would keep everything except terrain textures to high as I want the airfield that I'm at/taking off from/landing at to look nice, but I don't care how the ground beneath the grass looks, it could be low texture.
  18. High everyone, I am building a new computer and the only thing that's missing is the GPU. DCS is not the only game I play although it is by far the most demanding one. Now I know that this is due to ancient code and what not, and that as long as it's as is, we will never be able to achieve the performance we achieve in other games, but I would at least like to push it as much as I can. For months now, I see a fuck ton of benchmarks for " regular " gaming. In these benchmarks anything beyond a 6800xt or a 3080 offers an advantage that only makes sense if you have a couple of thousands lying around and don't know what to do with them. Both these cars are enough for everything. VR though is a scary, hungry monster and my headset in particular, the Pimax 8K X even more so! This is why I am making this post, in the hope that some 6900XT and 6800XT owners can come in and offer me their first hand experience regarding VR DCS. My brain, tells me go for the 6800. There is decent availability where I am and although the price premium is there, I can at least save 400-500 and throw that on some simulation hardware. My irrational fear of the VR boogieman though, tells me that those 5-10 frames or whatever that the 6900 will provide may mean life or death, or in this case, provide me with some much wanted breathing room. This, and the fact that I do not wish to upgrade every time a new thing comes out. Usually I keep my system intact for a minimum of 2 years and then build a new one from scratch. ( Last system with a first gen Ryzen and a gtx 1060 has served me with distinction! For christ's sake, it can even handle VR at a capacity which is not motion sickness inducing! ) So what are your thoughts? 99% of the games I play will not make sense for me to get the 6900. That 1% however, which is DCS is my most favorite game and so I am perfectly fine wasting some hard earned money if it means I'll get just a little bit closer to the fabled 70+ FPS experience!
  19. I don't get why this has not been fixed for how long it has been in the game and is now a module on sale. When ever the radar on the Mig21 sees the ground my game just drops from 150 FPS to 10-20 FPS. I have looked for ways of fixing this and found nothing that actually works. If any one knows if they are working on fixing this or if there is a fix that would be awesome, just putting this out here to hopefully get some attention for this problem.
  20. Hey all, I tried browsing the forums for a few minutes and could find similar issues but not identical to mine though I may have just missed it. I upgraded from the Odyssey+ to the Reverb G2 about 2 months ago. Game runs great in VR, both in the O+ and Reverb G2, only issues is when I go back to spectator online. The game will stutter near to the point that it's unplayable, but it seems to only happen when I return to spectators or respawn aircraft, otherwise it runs near flawlessly for me. If I look in one direction it runs fine but as soon as I adjust my head position to view instruments post respawn, or look around, the stuttering resumes. I never had that issue with the O+, so it seems to be G2 specific for me, I have tried adjusting and changing various graphical settings, VR settings, etc. with the same results. I am unable to pin down exactly what is causing this issue for me. If I return to the main menu the stuttering stops, as soon as I go back into multiplayer, it resumes. If I restart DCS it runs great until I respawn then it starts all over again. I'm kind of at a loss as to what is causing the stuttering to occur as it only occurs under those conditions, trying to find out if anyone else has had the same issue and if so, if they have found a work around.
  21. Hi Everyone, First post in the forum - and please come and shoot me down online rather than flame me here - I am usually growling on the sidewinder server Let me know if you have any tips beyond the ones below? For improving online play mainly. Shader replacement seems so so, as sometimes I fail to pass check so I stopped that approach. ----I have an old Dell workstation 32gb ram i7-3770 (9 year old cpu) - for other games it keeps up - but DCS. The CPU is my bottleneck. Config: For VR i got a G2 Reverb and 3060Ti to replace my 1060 (non VR the rig was 50-80fps on the 1060). I figured I would document and share my experience at getting FPS out of my rig, as best as I can and some tweaks which perhaps can be helpful to others. > Pixel density 1.2, Shadows Flat, Ground @ Low - Grass Off - (no heat no dirt) - hotplug disabled > Steam VR resolution set to 1900x1900 or so - no smoothing, as that seems to make things jittery > To get extra 45% in FPS (single player from 30 -> 50fps) (multi from 15/20 -> 35/40 fps) :: SMT Hyperthread disable totally helped > To get extra 5 FPS and minimize ram on the VR - went to download Skyscenes and installed "Empty Room" as default Windows Mixed Reality Starting space > VRAM use went from 3.2gb to 2.5gb (with no game running) > To get extra 5 fps > disabled secondary monitor and set primary monitor to 1920x1080 and right click on desktop - hide desktop icons > To get extra 3-4 fps and prevent memory swapping into video memory modified default Hanger to NOT load anything in VR (this prevents your VRAM getting slammed with a pretty hangar..oooh..who cares) I cut out all models from loading: DCS World OpenBeta\Scripts\DemoScenes\sceneVR.lua (backup your file as a copy before you modify it) bottom line, GPU FPS is ok.. but still my CPU is getting nailed. in single player its happy, in multi it gets destroyed and brings the fps down..but at least I can still fly for another year or so until I get a new mobo/cpu/ram on this rig at around 45-50fps in multiplayer.

  22. Hey Guys, there is already a thread to this topic - but it is in the VR-Section and I wanted to report about my experiences in Pancake, so I figured to open a new topic. In short for those who are unaware of it: With the latest GeForce-Driver update, Nvidia upped it's sharpening feature to an universal upscaling algorithm similar to AMD FSR. It is pretty easy to use. Just activate the option in the 3D-Settings (you may also check the box for the overlay, with gives you an indicator when the feature is running), go to resolution and look for the scaled resolutions (85%, 77% and so on). Remember the odd resolutions, that comes with your desired upscaling tier (I went with 77%), but LET THE RESOLUTION SIT ON YOUR NATIVE ONE (Important!). For me the native Resolution (4K) is 3840 by 2160. The NIS 77% Resolution is 2956 by 1662. Now start DCS, go to the settings and change the resolution to the odd one from above. The option should appear in the drop down menu. Done. When you selected the overlay in the nvidia settings, you should see a green NIS in the upper left corner of the screen, when it's running. The results for me were the following: (GPU is RTX3080) Baseline (native 4K with msaa 2x): 19-11-2021, 18:24:08 DCS.exe benchmark completed, 10911 frames rendered in 140.047 s Average framerate : 77.9 FPS Minimum framerate : 69.3 FPS Maximum framerate : 87.2 FPS 1% low framerate : 68.9 FPS 0.1% low framerate : 67.2 FPS 4K with NIS (77%) and msaa 2x: 19-11-2021, 18:05:01 DCS.exe benchmark completed, 13512 frames rendered in 139.797 s Average framerate : 96.6 FPS +24% Minimum framerate : 86.0 FPS Maximum framerate : 107.7 FPS 1% low framerate : 85.7 FPS 0.1% low framerate : 84.3 FPS 4K with NIS (77%) and msaa 4x: 19-11-2021, 18:12:32 DCS.exe benchmark completed, 11569 frames rendered in 139.890 s Average framerate : 82.7 FPS +6% Minimum framerate : 73.0 FPS Maximum framerate : 92.2 FPS 1% low framerate : 72.8 FPS 0.1% low framerate : 70.9 FPS There are of course penalties in visual fidelity, but those are pretty small, given a 25% FPS-Increase. With msaa 4x and the sharpening factor tuned, your pretty close to the original quality. So if you struggle with FPS OR need some headroom to activate other options, NIS is a pretty solid option imho. Have Fun! EDIT: For those who use a TV instead of a Monitor (like me), it can be a bit tricky. There could be additonal hurdles to take. If you run into problems, let me know. I may be able to help. EDIT2: Added the detailed FPS-Numbers (note that I changed the settings over the original test, therefore the numbers are a little lower, but the percentages are the same.
  23. BLUF: Thrilled to be back...been jealous reading the forums and watching evolutions of DCS over the past few years. Would appreciate your help, so skip to the Questions section to bypass my melodramatic summary… I love DCS…I could not be happier with the trajectory, and it’s thrilling that study sims are making a comeback. I attribute this largely to IL-2 (including RoF) and DCS....things certainly seemed dead even in the early 2010s. So happy I no longer have to dwell on my first study sim loves: Microprose F-15 SE III, Janes F15, Longbow. However, as with many of you, it’s been a love-hate relationship that has ebbed and flowed over the years…here’s my quick story (please correct if memory provides inaccuracies): My DCS Story: 2009 – started with OG Black Shark CPU: AMD Phenom II 965BE GPU: Single HD5970 Top-of-the-line system; ran well, maybe 45fps, generally had a good time at 720p during real missions 2010 – picked up A-10C and never went back to Black Shark CPU: AMD Phenom II 965BE GPU: Single HD5970 Perf degrading, usually kept over 30fps at 720p...I started to get concerned. Generally enthralled but not much campaign/community content…interest came and went. Sadly, this would be the last year I could play DCS well on my 2 year old system (was top-of-line). Fun note: I have a good friend who’s an AF Hog driver (AETC) and back in 2010 he sat with my HOTAS Warthog, flew the sim, and could not believe it…just now in 2021 he sent me a link to this article: https://www.thedrive.com/the-war-zone/40620/a-10-warthog-pilots-are-using-the-digital-combat-simulator-video-game-to-train-in-vr 2011 – DCS World launched…perf got worse, still only flew the Hawg CPU: AMD Phenom II 965BE, but OC’d it more…didn’t help much (see BLAB) GPU: 2x HD5970s…added another card, didn’t help much (see BLAB) Struggled with maintaining 30fps at 720p BLAB: DCSW does not utilize multiple CPU cores well, nor does it utilize Crossfired GPUs. Super! At least I could play all the other games…so I often did for the next 4 years. :( 2015 – DCS 1.5 launched; DCS 2.0alpha launched CPU: AMD Phenom II 965BE GPU: New GTX 970 helped me take a swipe at 1080p…but just barely Struggled to stay above 20fps at 1080p during heavy action EDGE turned out to be a great long-term bet by ED…yet it did not solve my now very aged CPU/GPU combinations or fix the single-core single-GPU emphasis (as some suspected it may). 2017 to 2021 – sent overseas for 3+ years CPU/GPU: Packed away in my HHG, no sim’ing, no fun… At least once a week….for 3+ years…. I read about DCS’s progress and watched the YouTube/Instagram videos proliferate…could not BELIEVE the announcements around F-16, AH-64D, F-18, F-14…WOW! Mind blown…but all I could do was track things and wait to return back CONUS to give it another go. 2021 – DCS 2.7, I gave up and went gangbuster…didn’t even try to run on my old system CPU: i7-10700K OC’d to 4.85 GPU: RTX 3080 NOTE: I did try using my GTX 970 with the new CPU…and still only managed 30-45fps at 1080p. HAHA! Just proves you need both CPU and GPU to be top-of-the-line to really get any mileage out of DCS. For the first time in 10 years, I can play DCS smoothly again…and for the first time ever I’m at 60+fps on Ultra doing 1440p. IT IS INCREDIBLE….and it only cost me about $2,400! My Beefs with DCS (I love all the same stuff you love, btw…that list is too long): Performance = no question here…it costs a fortune to run DCS well and consistently over time. And I’m praying that my current top-of-the-line system keeps me at playable framerates longer than my last top-of-the-line system (2 years). Reliably merging the Aircraft with the World = missions/campaigns still seem super-buggy and constantly requiring high-LoE updates to maintain functionality as DCS constantly upgrades. It sucks to just be doing the same out-of-box missions from 2010 for A-10C. ED: you guys built these AMAZING high-fidelity aircraft…and this incredible digital world with beautiful clouds, terrain, and units on the ground…but are failing at unifying those 2 aspects together in a reliable and consistent way via community/ED-sponsored campaigns that do not fall apart every few months. [head-on-desk] My Questions to the community: Is ED seriously not supporting Red Flag for NTTR and A-10C II on 2.7? Building NTTR seemed like a questionable gamble for ED (not sure it paid off considering the new theaters, little content for NTTR I see now)…but having worked there before, I LOVED IT. And I adored the Red Flag Campaign…so is ED also falling victim to their own AI-brutality in mission design breaking with upgrades…is it too much of a pain for even ED to update? Should I ask for a refund here? Why does A-10C original even exist? I was quite surprised to see that OG A10 still is a separate module…how confusing and unnecessary. Why? It’s been over a year. All the content should be A-10C II by now… What SP campaigns should I play for A-10C II? Seems like just Enemy Within 3.0 - really? I want Red Flag…but see above. I played Enemy Within back in the day…happy to see there’s a 3.0 supporting A10-C II here. I see Piercing Fury is user-supported now…but it’s failing me on Mission 2 (I saw the fix threads…but don’t have time to screw with this stuff in the waning hours after the kids go to sleep…I just want to fly and blow sh*t up, fixes not working for me). Given the above experience with A10-C II - what do you think of investing in Hornet? What’s the single player campaign story there? I really want to dive into the Hornet once it goes on sale. I’m thinking to buy: Hornet SuperCarrier Persian Gulf Raven One But that’s a lot of money just to potentially be disappointed that I cannot play through campaigns after upgrades, etc. Other recommendations? I bought F-14 from HB…even though I won’t have time to study it. Just bought because I read they did a great job and want to support 3rd party on awesome modules like this. I’m definitely going all-in on AH-64D (same story, support the cause) but again worried about SP Campaign content… Thanks everyone and cheers
  24. Personally, I think that FSR will be an incredibly useful addition to DCS, especially for people with lower end computers. Disclaimer: I'm not a developer so this information may not be accurate, please take it with a grain of salt. What is FSR? As I understand it, FSR, or FidelityFX Super Resolution, is AMD's alternative to Nvidia's DLSS. Both make the game look like it's running at a higher resolution than it really is, albeit with different methods. For example, the game can render at 720p, but FSR will increase the resolution and fill in the blanks to produce a 1080p output. It's a way of improving frame rates while trying to have a minimal impact on graphics quality. Everyone can benefit from it, especially those with lower end computers. So it's AMD's technology? What about Nvidia users? Unlike Nvidia's DLSS, which only works on high-end Nvidia cards, FSR will work on a much wider range of devices, including Nvidia ones. It will work on the Radeon RX 400 and up, Ryzen 2000-series APU's, as well as Nvidia's GTX 10, 16, and RTX 20, and 30 series cards. Also unlike DLSS, FSR is open source and not proprietary. How difficult would it be to implement? For other games, it has taken from as low as two hours to as long as a few days. Of course, DCS doesn't use a common game engine like Unity or Unreal, so it would likely take longer, but from what other developers have been saying it seems relatively straightforward to implement. Conclusion I'm sure I, as well as many other DCS users would greatly benefit from FSR being added to DCS, as it would be an excellent way of improving performance for everyone, while taking (apparently) only a small amount of effort to implement. Thanks. For more information, check out AMD's page on FSR.
  25. Hi guys, So basically, I need help. I'm going completely mad with my VR performances so far and I'm questionning what I've been doing wrong or if my rig is faulty. I hope somebody here will be my savior. Let's start with my setup then I'll explain point by point what I've tried and noticed. Setup Motherboard ASRock X299 Steel Legend Proc Intel® Core i9-10900X RAM GSkill 32GB DDR4/3600MHz GPU Zotac GeForce RTX 3070 Storage 1TB Samsung 980 PRO M.2 PCIe NVMe Cooling Corsair Hydro Series H100i Extreme Performance Liquid Coolin VR Headset HP Reverb G2 Flight Gear Thrustmaster Warthog HOTAS Stick & Throttle Trustmaster TPR Pendular Rudder UserBenchmark done today: https://www.userbenchmark.com/UserRun/45006662 Nvidia details Driver 471.41 See screenshots for settings Windows Settings HAGS - Off Game Mode - Off Fullscreen Optimization - Off DCS.exe vrcompositor.exe vrserver.exe all in High priority, added through Regedit Graphics performance preference - DCS.exe set to High Performance HPET - Disabled in Device Manager System page file - 32Gb Performance Options - Adjust best performance for Programs WMR Settings All by Default SteamVR Settings Using OpenXR at runtime. OpenXR Settings As I understand it, OXR settings don't apply to DCS even though SteamVR uses it at runtime for the G2 DCS Settings VR Settings by default (Pixel Density at 1, Force IPD Distance unticked, no bloom) Hotplug disabled. Environment No Chrome, no Spotify, no nothing but fpsVR. No DCS Mods but the VR Shaders I also have OpenVR FSR: https://www.userbenchmark.com/UserRun/45006662 Mission Environment I have a small multiplayer mission I scripted, nothing funky. Starts in Vaziani. I do all my performance tests and changes in the cold and dark F/A18. Attached is the .miz Mi-24P - Saving the 'murican convoy.miz Experience so far Okay so I guess it gives a proper idea of what I have in terms of setup and settings. I barely hold 30fps, cold & dark on the ground, with that whole configuration which is pretty disappointing for me considering the visual compromises and my setup that i would qualify as decent (it's a month old, all new pristine parts). I have followed several guides to improve performances. Guide specifically for the G2, guides specifically for the 3070, guides specifically for the G2 AND the 3070. When i see some posts on these forums showing 45 to 90fps in average with "weaker" setups, I'm just wondering what the heck I've done to Saint VR to be stuck at 30fps in a cold Hornet. Just to be clear, I am not a FPS chaser. I aim at 45 to 50 without multiplyer and without streaming/recording so that i can have a steady 30 to 35 when both in MP and streaming/recording. I have tried to put all the settings down to the bare minimum and got different results (which i can't really explain either). -90 fps (fpsVR) in the cold & dark hornet when i start the mission for the first time after booting the game up from SteamVR (meaning starting SteamVR first and then inside the headset to start DCS) -45 fps with the EXACT same settings and the EXACT same configuration after moving up some sliders and settings, applying them, starting the mission (crying because 20fps), stopping the mission, going back to settings, going all the way back down for everything then starting the mission again. -40 to 45 fps when launching the game not from Steam but from the shortcut on my desktop (I have the standalone version that i added as a non-Steam game on Steam), no matter if it's the first execution of the mission or not. -Randomly less then 20fps and huge stutters after starting the mission several times because i'm trying to tweak the settings and got back to the lowest possible Performance results As I mentionned, i barely hold 30fps with that configuration but here's a more in depth summary. GPU Frametime is 15 to 18ms in average depending on where i look in Vaziani GPU is at 58°C GPU is used at 35% in average SteamVR SS is shown at 50% GPU Mem is shown at 7.5 out of 8 Retro-projection ratio is shown at around 60% in average CPU Frametime is at 30ms in average CPU is at 65°C CPU is used at 65% in average CPUs are at 85% 20Gb out of 32Gb of RAM 2 dropped frames after 5min of time Overall smoothness is ok, the view doesn't "grip" when looking quickly around me. Obviously as soon as the aircraft is live and i have, let's say, the FLIR and a MAV on each DDI, I get stutters and the fps drops at 24/25fps in average. Conclusion What do you guys think? Is there something really obvious that i missed? I hope one of you's gonna be my angel because i'm literally clueless. Thanks for reading, -Hina
