Hi Helpers. been away from DCS for a while, but wanted to explore the new Marianas map among things. Just installed the latest 2.9.17.11733 update. I found with my AVA base the axis behavior now quite stuttery, while it worked fine before the update. It also still works fine with IL2 Great Battles BTW. Also with DCS it seems the AVA's axis does not reach the full range (both X and Y) any more. ------ My warthog throttle works fine, nu stutters, full axis rage, but maybe it's a TM AVA or windows issue? Ran a full repair, (no mods etc) and even reinstalled the Thrustmaster's latest 1,14 drivers and firmware. NADA, any one also experienced this? PS is there a way to check windows further on this? ADDED: FIXED: there's a firmware update for the AVA base needed for the latest windows versions, DCS is fine now.

I started this topic to track and discuss challenges with getting the best performance out of the system. I usually test each setting a couple of times. 27-1-2025 Nvidia 571.96 DLSS 4.0 Installed the new drivers. 25-1-2025 Adjusted GPU Overclock Increased CPU PBO Scalar and reduced some of the GPU overclock to further increase fps and frametimes. Time will tell if it also stays stable on the MP-servers. 18-1-2025 Clean W10 Complete reinstall of W10 returned another 5fps and better frametimes. Over the years the system got bloated with all sorts of traces from old hardware that I upgraded (2x GPU and CPU) and software that I tried and not fully removed. The system is snappy and clean again! I considered W11, but there are too many bad stories out there, no clear advantage for AMD and GUI modifications with taskbar etc W10 is easier. The only thing I still notice is that it seems that when I hit the FPS limit some sort of trouble in FPS and frametimes appears. When I stay a bit below 90, like 88fps, it is more stable. 27-12-2024 Current Overclock settings 64GB ----- EXPO: ON (timings default as stated on the DIMMS) 9800X3D ----- Turbo Game Mode: ON PBO: +200 Curve Optimizer: -20, FCLK Infinity Fabric: 2200 UCLK DIV1 Mode: UCLK=MEMCLK, SCALAR 10X 4090 ----- Core Voltage: +100 Core Clock: +120Mhz Memory Clock: +900Mhz, Fan: Power Limit 133%, Temp Limit 84. This GPU overclock is stable and gives me 4-5 extra FPS, even when i am CPU bound. My setup Windows 10 - latest version - Windows 11 will not happen until I will get serious latency advantages. Motherboard: ROG STRIX X870E-E Gaming WIFI Systemboard VR Headset: Varjo Aero SSD for DCS and Windows, separated DCS Settings Most are set to the max. SSS, Secondary Shadows, SSAO, SSLR are disabled; they do not bring much visually. Visibility Range Extreme. I have Visible Range set to High. Increasing this further is not bringing much visual improvement and really takes away performance. MSAA Mask Size 0.42 is my sweetspot. Testing Setup and approach My Windows has been heavily tweaked and optimized and I am currently still running the same Windows I started with 5 years ago. I upgraded my systemboard, CPU and GPU a couple of times but did not reinstall Windows. I think at certain moments in the past I even went too far with tweaking and should have dialed back and better register what I was doing. So a clean install will be somewhere in the near future because I am certain I have left quite some performance on the table. For the basic quick test of setting adjustments or hardware/software updates I start a the default A-10C mission Runway Startup on the Marianas Map. I use Marianas because this mission is quite demanding and quite stable almost from the start with AI not doing much. I let it run a couple of times for 20 seconds and track the performance with CapFrameX to calculate the average FPS, 1% and 0.2% lows of the runs. Many other missions give me 90FPS, so adjusting settings with such missions will not give me noticeable visible differences. If I want to visually see the performance I open up the the FPS overlay inside DCS. I sometimes also open up the new XRFrameTools application to visualize my frametimes. Once a setting looks pretty okay I log into our Wing's Multiplayer server, startup OBS recording and give it a spin to see how it goes. I usually get 90FPS flat in this setup, while running OBS recording. Testing log From now on I will start adding my complete testing logs to this main posting. Where relevant I will add charts to visualize the difference between certain options. Certain tests were eye-openers. It was/is a dreadful process going through all the settings and quite a few settings were insignificant in my case. Frame Times, average FPS, 1% and 0.2% Lows My main goal is to find the ones that will bring more stability (reduction of intrusive stutters) and performance (increase of FPS/frametimes). Sometimes it is like searching for a needle in a haystack. Seeing the settings that made a difference might bring quick wins to others as well. Overall the average FPS is not improving that much by all the tweaking, it is easy though to screw up your system and reduce FPS. But once the FPS are pretty decent it is hard to get substantial improvements. My biggest wins are with the 1% and 0.2% lows, reducing these give a much better overall experience than to have 1-2 more average FPS. The overall FPS can be high, but when you have a few microstutters here and there it is very annoying and for me breaks the immersion in VR. Caution Please be careful, not all what works for me might work for you. Do everything at your own risk. I had some crashes, especially with the overclocking, so always make backups and restore points. I also don't have my overclock software start automatically anymore when tweaking, because that also caused an issue once causing me to keep rebooting into a crashing configuration. null null null

My system is an i9-13900k on a MSI Mag Tomahawk Max wifi, Asus Tuf RTX 4090, 64gb DDR 5, 2TB Samsung SSD. I'm using a Pimax 8kx until my Crsytal Super arrives. I'm wondering why I'm getting stuttering when the Nvidia overlay shows my GPU and CPU are hardly breaking a sweat. I also installed Capframex, MSI Afterburner, and Riva Tuner, but I can only test with those tools using my monitor which is pretty much a waste of time. (Anyone know how to get the overlay to display while using VR headset? The Nvidia overlay displays on my monitor while I'm using the headset, but I can't get the Afterburner overlay to display when using VR). Nvidia reports my GPU usage is often in the 40s to 50s and the CPU is in the teens to mid-20s. Unfortunately, the Nvidia overlay is pretty limited and doesn't show all cpu cores, frametime, and so on. I'm wondering if I need to spend another $750 for a 9850x3d and mobo to make this problem go away. Oh, I tried overclocking the cpu using the Gameboost option in the mobo bios - stock clock is 3.0 and now it's running at 5.6Ghz...but that didn't make the GPU work any harder. I would prefer to keep the $750, but I'm at a complete loss of what I need to do to coax this system to work harder. Any suggestions are welome and appreciated!

Recently back to DCS VR, but find out I keep getting stuttering frames.... and it getting worst when I in MP server. so I started looking for the way to fix it and nothing help at all for now My environment: 13th Gen Intel(R) Core(TM) i5-13500 DDR5 32GB NVIDIA GeForce RTX 3060 12GB Quest 2 with Virtual Desktop but OpenXR (VDXR) Quad-Views-Foveated F-14B DCS STEAM beat (MT)openxr what I have tried: 1.Turn off DLSS 2.NVIDIA profile settings(see attachment) 3. DCS System settings(see attachment) 4. disabling Intel E-Cores(process Lasso) 5. Exclude directories in Windows Defender can someone help me? the video will show how bad is the stuttering thank you! DCS setting: null

Good morning, i fly in VR with a decent fps level, but face an issue when accessing to the esc menu. Once on the binding change menu, the screen stutters badly, to the point that the computer even sometimes freezes. Any experience / advice on this? using a G2 on a custom laptop, rtx3800, i7 10th gen, steam overlay but standard dcs. thanks

I have been testing a 3090 and a 6900xt in the last weeks on my rig - was running a water cooled 1080ti before (the system itself is an Asus Z390 Maximus Gene with an overclocked 9900K and 32GB kit of DDR4-3600 with very tight timings). I tested both a Rift S and a Reverb G2. During my testing I made the following observation: Either letting the GPUs doing their job in the out-of-the-box configuration or alternatively overclocking the GPU manually created in both cases a tendency towards stuttering and very pronounced frame time spiking for both vendors though the green team doing significantly better here. This was very surprising for me since I used the identical graphics settings I had for my 1080ti which didn’t show any stuttering. I expected those settings to be a piece of cake for the flag ships cards of team green and red. So I started to play around. Fixing the clock rate by a defined voltage (aka undervolting) on the 3090 eliminated all frame time spiking and stutters. On the 6900xt it helped a lot to prevent the GPU from using the out-of-the-box efficiency behaviour (which is very aggressive on RDNA 2) by forcing it to stay within a defined clock rate speed (when the CPU struggles with filling the draw call pipeline Big Navy seems to drop into a short power saving sleep). The difference to the out-of-the-box behaviour is basically one thing: The GPU doesn’t boost anymore. And the boosting process itself seems to be counterproductive in DCS VR. Looking back to my old GPU this somehow confirms my observation: My 1080ti had several manually optimised voltage curves which I made for specific applications and saved as profiles in afterburner. One curve was exclusively for DCS and it definitely never let the GPU go into boost. Since I don’t want to generalise my experience I would like to hear some more voices here. Anybody here with a similar experience? Since heavily overclocked and maxed out GPUs are not uncommon for VR users - anybody with stutters in VR (and an overclocked GPU) willing to try an undervolting approach and report his results?

Just installed a pair of lcd screens behind the Cougars. It looked okay, but the frame drop and stutter is unforgiving. I have a Ryzen 5600x, 6800xt, 32gb, 165hz monitor @ 3440x1440 rig which is quite smooth with all graphic options pushed to max except for AA and RT . (only play SP so far) But once I start pushing screens to the MFDs, it is choppy as @!￦#. (freesync is off) I am exporting via monitorsetup lua file adjustment(file attached). Freesync is off and total resolution on options is 4240x1440p (MFD LCDs are 800x600 each and are stacked on top of each other/ to the right of center screen) ANY Help would be greatly appreciated MFD export.lua

I’ve been having stutters basically since switching to VR. Sometimes it would feel almost good, sometimes not. After fiddling around with settings I’ve come up with a setup that would give me consistent 11-12 ms per frame both GPU and CPU time which seemed like a sweet spot for me. I changed G2 to 60 Hz (flickering doesn’t seem to affect me much). The only remaining problem was dropped frames. The issue has become more pronounced recently so I decided to dig internet a bit more and found 3 solutions which completely eliminated dropped frames and keep perf overlay of OXR green as dollar. The first 2 seem to be the most useful. Give them a try and see if it helps your problems if you have any. I’m sure the things here were already discussed on the forum but I decided to share what helped me make my game playable again. I run OXR without any shaders or toolkit with 10 gb 3080/12700kf combo on Win 11 1. Go to computer management - performance - data collectors set - event trace sessions. Find Holographic shell and stop it. If it helps, do it every time you start VR. I have no idea what it is but apparently there's some sort of conflict between WMR and this service after 22H2 update which causes notable stutters. In my case I was sitting at frame times consistently below 12 but performance overlay of openxr was constantly changing between green and red (lost frames). Same with SVR (purple frames). As soon as I stop it it turns green and stays green. 2. Go to windows search, type services, launch as admin. Find power, double click it, change start up type to "Disabled". Apparently, it tries to manage power of the CPU and when disabled, CPU runs at consistent (max?) power. 3. DISCLAIMER: doing point three should be safe for your system but all what you do in the registry editor is completely your responsibility. If you are WMR user, you probably noticed that when VR is enabled (WMR app is running), in display settings you have 3 extra monitors. Those are virtual desktop and are used for various apps launched inside VR (such as browsers, etc.). In WMR every such app requires a virtual desktop and to avoid a lag when opening one of those it creates 3 in advance. If you're not using VR for anything apart from gaming, you can disable those. For me it reduced CPU consumption for window manager process or whatever it's called. It may also possibly slightly reduce VRAM consumption as those desktops will not be rendered in the background (or at least that's my understanding) Go to regedit and go to HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Holographic Add DWORD 32 bit PreallocateVirtualMonitors and change value to 0 Happy flying!

Hey everyone. I am another one of the unfortunate ones experiencing an exasperating issue with my performance in VR. I got a 4080 a few weeks ago to help with VR performance. Not only does my performance seem worse than my old 3070 (was running 45fps reprojection and 0.7 PD) but no matter what I do I cannot seem to find a solution. While in DCS I experience stutters consistently. The major symptom I am seeing is frametime spikes in the framerate monitor and every spike corresponds with a slight drop in FPS for a split second which results in dropped frames or something which I can visually see as as stutter. If I am looking around in particular I can see every stutter even though the actual frame rate remains high (90fps down to maybe 82). I've dropped my settings as low as they will go and even dropped my render resolution to 30%! Same issue albeit the stutters weren't as consistent but rather more random and "harder" if that makes sense. The symptoms vary in severity based on settings of course but the end result is the same. I see a stutter or stutterS in my headset and its driving me crazy. The worst part is when I am lucky and not actively getting stutters, even with moderate settings, my frame times and frame rate are rock solid at 90fps. I don't know what else to do at this point. I think I have tried everything. I'll put a list of things that I have tried so far as well as some screenshots of the frame counter. I know I am not the only one with similar issues but I am posting here to HOPEFULLY get one piece of advice from someone with a similar system or issue that has solved this. Thanks in advance. ---------------------------------------- All the required uploads per the ED forums are attached... at the bottom. --------------------------------------- System Specs: i713700k - H150i AIO Cooler(great temps) ASUS ROG STRIX Z790-E Gaming WIFI MB 32gb Corsair Vengeance DDR5-5600 XMP1 on ROG Strix 4080 White OC Samsung 980 pro NVME Windows drive 980 Pro DCS NVME SSD 850W ASUS ROG Strix Power Supply Reverb G2 VR headset Here are some screenshots of stutters and smooth operation alike. All in DCS MT Smooth operation. Looks epic and smooth!!!!! Stutters of a more consistent nature. This is in Syria but I was getting this same symptom in all the maps. Notice in this one that the performance is awesome very stable until I get spikes. These are different than the smaller spikes above but are "harder" and more visually jarring. Changing settings didn't make too much of a difference in getting these. YES I KNOW THIS IS IN THE AO and multiplayer plays a factor. Just needed the reference photo. Again good performance most of the time then when looking around will get these single random stutters or a few here and there randomly. Here these are some really nasty random ones. Mostly when looking around. I hope this post accurately shows my symptoms with the screenshots. Here are some of the things I have tried so far. -DDU drivers -Low settings, DCS, Open XR Tools for WMR, etc. -Motion reprojection - seems to alleviate some of the performance related stutters but still get quite a lot of stuttering especially those random "hard stutters". I am not a fan of the artifacting and ghosting caused my MR. -Reinstall DCS completely. Saved games and the lot. -Frame locking - causes issues with the VR headset it doesn't like that at all. -Open XR Toolkit - Turbo mode on/off, FFR, motion reprojection -Core affinity using Process Lasso - disabling E cores and even some P cores to avoid 100% usage -Disable E cores completely in BIOS -I even reseated my GPU! -Slight overclock on GPU, MSI afterburner -forced VR and Open XR -DCS Single Thread seems to be different (???better???) in terms of stuttering but performance is overall less so I get less frames overall and that causes some micro stutters due to differing frame rates vs refresh rate of the VR headset.

Hi all. Can someone help me please? My name is Dave & I'm a DCSaholic. Seriously though I'm hoping someone can help with an issue that's cropped up fairly recently. Up until a month or so ago, everything was running really well, even VR only stuttered once in a while, but then for no apparent reason it started to stutter & drop frames in both VR & using the pancake. I hadn't changed any of my settings on the GPU, the PC or DCS. After the MT update I was hoping that this would improve things but nope. CPU usage has gone from 15% to 39% & the FPS has jumped up, all which are brilliant improvements, but still getting the stutters. I've tried reducing the graphic fidelity, still stuttering, tried different GPU settings. ... still stuttering, & I've not dared go onto a multiplayer server & aren't even going to bother with VR until I've sussed what is happening. Does anyone have any ideas that might help please? My system has a Ryzen 5800X, 64Gb of 3600mhz RAM, an RTX3070ti GPU & I'm running DCS from an SSD. Thanks for any help in advance.

You're going to find all you need to know in the link below : https://www.wikihow.com/Change-Mouse-Polling-Rate **If your mouse has no software, no problem, in the link you'll find one universal software, I installed, super easy, works! I've underclocked my mouse, 1000hz to 500hz (HZ IS NOT DPI). **You may still experience some fps drop and stutter for many other reasons.

See title. I've already cleared fxo and metashader folders before this mission. DCS log attached. Any help would be much appreciated. It's so annoying to pay for a module only to see it as a slideshow in game... dcs.log

Just wanted to share this in case it works for anyone else. nullSetting Vsync to "Fast" in NVidia control panel has improved significantly my gameplay in VR. The FPS remain the same, but I do have way less stutter. I still have some stutter in the mission I used to play before 2.9.6 (a sandbox mission in Syria with custom scripting and many statics and units) that used to work smothly but was now unplayable... Other sandbox missions I made in Kola and Afghanistan are now stutter-free (fingers-crossed), so at least I have some hope now Edit: unrelated, but reducing resolution in the first DCS setting does seem to improve 5-10 fps. I know, it has no sense, since I play in VR with "Use DCS system resolution" option checked... but I do swear it has improve in my system

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.

Hello, everyone. This problem has been present since I moved to my new rig just yesterday. The game (both multi-thread and single-thread) seems to stutter for a fraction of a second at random intervals. This happens on all maps, in all aircraft that I own, usually anywhere around 2 to 20 seconds between each other. One way I can increase its occurrence is by maneuvering the aircraft. I have tried everything to my knowledge, with the help of a couple of other friends, to fix this issue, but to no avail. My graphics options are: My specs are: MSI B550-A Pro AM4 ATX Motherboard NVIDIA GeForce GTX 1080Ti 12GB GDDR5X AMD Ryzen 9 5900X 3.7GHz 12-Core Processor Corsair Vengeance LPX 64 GB (2 x 32 GB) DDR4-3200 CL16 Memory M.2 2TB SSD Corsair RM850X 850W 80+ Gold Power Supply I play with TrackIR on a flat screen with a 239.760Hz refresh rate. Attached is my dcs.log . All I did was spawn in, and after a few seconds, the game stuttered. Also attached is a regular speed and slow-motion recording of what one of these stutters looks like with the additional statistics. (This was done in MT, but does the exact same in ST) When it comes to solution methods, I have done everything from hardware stress tests, to BIOS updating, from repairing/cleaning out DCS, to following multiple video tutorials on how to optimize DCS through the NVIDIA Control Panel. So far, nothing has worked. Help would be much appreciated! dcs.log Framerate Spike Slow Motion Data.mp4 DCS Stutter.mp4
