fab.13

Hello, True, I had to disable HT in the first release of MT in 2023 "give a try " was intended for player that met stutters at this time to test that option ( i was not alone ... ), not a recommandation. From few release after summer, i remade some test with a bench track and it was better with HT ON ( but with no shadow ) Now with the last release delivered in Feb 2024, DCS is very smooth and i could have increment resolution in VR in my quest 2 ( x1.3 ) : great !

Hello interesting… You got a bench method of your DCS machine I’ll test that on my side

Stutters could have a windows root cause Flappie has written in this forum all windows settings to allow best DCS VR experience about DCS, try ´vr settings’ tab or lowest settings ( texture resolution and AA technics to off , no shadow )

On my side, i launch DCS from the shortcut on monitor screen (DCS mt version) and not from within the headset … check that you are using the DCS multithread version now you get an error, you shoukd provide the DCS log to DCS support, or post here too

Maybe vram caching, so not managed by DCS itself Anyway, if your game experience is good and better with your tunning, don’t look too much at monitoring and play

Did you try a another VR ( free) Game ( pc vr game with link ) ? Last time i got black screen in headset was due to agressive settings in link, so i suggest to reset all settings to default and run without external tool or Mod ( no ODT): stock stack And check that ´unknown source game’ is on in occulus home

Hello check OpenXRruntime is enabled in occulus home reduce bitrate with ODT ( dynamic byte rate should be good as a first choice ) check Windows Swap file is enough ( virtual ram )

Intel I5 10600k 6 cores 12 threads 5gz 1080ti Quest2 64 GB ram windows 10 I’ll try some quadview settings in a next test It is not a problem because 2.9 works very well for now ( 72 hz no stutters )

So Quad View works on Intel I5 10600k 1080ti Quest2 FPS are not as good as without QuadView, maybe missing some CPU power on my rig...( default quad view setting, just turbo mode off ) So i removed it I prefer settings same as @Chapa ( no AA and Render Resolution Up , very smooth and clear ) @Granny you should be able to test QuadView The log file of quadview in '...\AppData\Local\Quad-Views-Foveated' indicate it's working 2024-01-26 20:35:53 +0100: Session is using quad views 2024-01-26 20:35:53 +0100: Edge smoothing: 0.20 2024-01-26 20:35:53 +0100: Sharpening: 0.70 2024-01-26 20:35:53 +0100: Turbo: Disabled

Let’s check the change log of the wiki I found this chapter about foveated redering and supported graphic cards: https://mbucchia.github.io/OpenXR-Toolkit/ So i'm confusing Foveated Rendering in OpenXR Toolkit and QuadView Let's try quadview with my 1080ti !

Hello QuadView need 2000 nvidia series minimum as indicated in docs when i tried ( tested a long time ago on my 1080ti ) let’s see if a commit has added support to 1000 series

Hello @Granny Here my settings from various stack, i'll update it... BIOS settings: - XMP and DDR RAM with low latency - no virtualization - enable virtual threads ( 6 physical cores -> 12 threads ) - i don't remember everything Windows 10: - you need the more RAM & VRAM free and low CPU : - check with Windows Task Manager, CPU should be under 3 or 4 % ( 1%-2% on my rig ), so disable some services and auto started application you don't need - check free physical memory while playing DCS ( some mission or mutiplayer server ask nearly 28-30 go RAM ) - disable windows auto update ( it take CPU and Network ) - disable HAGS - disable XBOX GameBar - disable memory compression - disable some MS assistant - exclude DCS directory from antivirus ( and "saved games\DCS* " too ) - power managment to maximum performances - disable usb devices power saving - stop every tool about performance : it take CPU ! - you get a clean windows and nothing more and with CPU load in background and RAM free... Nvidia Control Panel: - Specific DCS settings with Power Maximum Performances, textures quality performance, ultra low latency, 1 pre-rendered frame, no msaa, no fxaa ( max perf ) - i don't remember my nvidia driver version Occulus Debug Tool: - Specific DCS settings with "low resolution mirror" to 800 * 600, PD to 1.0, fov 0.9 x 0.9 ( depend about your Quest 2 mask ) - Quest Link : Low curvature, enable Dynamic BitRate Occulus HOME: - quest setting resolution to 1.2 - check cable link speed ( i get 2.5 gb with a standard usb-c cable ) DCS: - DCS OpenBeta stock with no mods - start with "VR Settings" : every textures low, no effects, no msaa , no asitropic , no shadow etc... ( max perf ), PD to 1.0 - disable HotPlugIn 1) start ODT first and check setting 2) start occulus home 3) connect your quest 2 and check resolution settings and everything ok in the occulus world ( smooth ) 4) Start DCS MT version 5) check in a free flight in caucasus with no weather effect : on my rig a get a smooth experience 72 fps , no stutter and no blurry 6) check on aerobatic server : a get smooth experience 72 fps, sometime some stutter when a new arcraft appears ( depend about the livery ! ) 7) change settings one by one ( Occulus Resolution or DCS : AA settings , Shadow, and Textures Resolution need more resources than other ... ) In my experience, windows 10 or 11 tuning is the most important step, I cannot get a good experience without freeing ressources at maximum and permanently ( CPU & RAM background reduced as much as possible ) ( DCS would need a real-time OS or DOS ...: dedicated ressources ) When checking performances while playing DCS MT in VR : CPU is about 80% and GPU about 90% and VRAM Full ... Good Luck !

Hello, i run DCS on a corei5 10600k ( 6 cores ) and a 1080ti and Quest2 i ´ll share to you in few hours my settings that i’m very happy with ( fps and quality balance ) and external tools ( ODT, NvCP, windows tunings )

Hello about resolution, many quest owner let PD at 1.0 in DCS, and use the définition multiplier in occulus home ( x1.2 x1.3 x1.5 … ) my advice is to start from low settings ( low textures..) in DCS and do test in freeflight after adding options one by one ( backup file named « options.lua » when it’s good) dont forget to use mouse options to keep cursor confined to DCS

Hello 1)just check total memory usage in windows task manager while playing If it is upper than physical ram, so swapping on Drive occurs and performances decrease: add more physical RAM 32 GB is a good value for single and multiplayer session ( some time more because of memory leaks in some script ) 2) the more vram you have, the best it is for DCS ( reduce vram swapping with ram )

Sure, maybe it is occulus related for people with occulus and low performance machine , here is the link that help my experience

Hello on my 1080ti , reducing mirror allow to get 72 fps in the Quest 2, without reducing mirror, i get 36 fps ( asw kick on ) this setting in OTT has been given in a old thread in the forum and still very useful on my experience So my question about disabling mirror…

Many thanks Maybe mirror full control should to disable mirror completely ? I don’t know if it is alowed with openxr api or a DCS implémentation design choice Why ? Because on my side i can get better performances when forcing mirror resolution in OTT to 800x600 ( oculus )

Hello on my side i removed every additionnals tools ( like openxr toolkit ..) and redo all settings from scratch : DCS 2.9 settings, nvidia setting reset … then it run better than previous version for my needs it seemd ED has reworked the redering very well , we should hope the same job the vulkan version

Hello Virgo47 Flickering and random stuff is because an old nvidia driver i used ( see me previous post ) So it is solved on my side Your video show another problem , maybe another thread ?

Bingo ! I installed 457.30 ( already on my disk ) and no more Bug Sorry for the time spent about such thing Bye Bye Nvidia 3 series drivers , Welcome 4 ou 5 series and new settings ! Some people tested different driver version to compare performances...3 series was good on my side until DCS 2.9 Thanks !

The bug is not present on a fresh install on my older machine, so not easy to reproduce as you say The bug is present ( slow repair + newly "saved game" ) of my current game machine ( options.lua is stock ) Easy to reproduce on my side : just start from any airport ( see screenshots ) If a reduce the LOD Factor to 0.1 , the objects pop-up appears very far but are still present on horizon ( horizon is flickering with pop-up ) LOD setting and algorithm seem to be related as said in previous post The bug is systematic , i could stream a video through discord if needed... options.lua

From few tests i could have made The visual bug is visible near every airport on the two map i have tested : i have been testing Caucasus and Persian map for now The visual bug does not occurs when flying away from airport I started to donwload DCS 2.9 from scratch on my previous machine in order to compare with my current game machine.

UP Hello, Same bug here since 2.9 update and still visible with second patch Boats ( without texture ) pop -up and disappear randomly ( 2D, VR, MT, ST ) from cockpit or external view ONLY when on airports ( caucasus map, persian map ... ) Here are some screenshot of the problem And a mission to start in order to reproduce from cockpit view ( we hope it will be reproduced ! ) DCS 2.9 is stock and just patched : slow clean repair done, "saved game" renamed, etc... I can see some error in log , maybe linked ? 2023-10-31 19:23:53.518 ERROR EDCORE (Main): No suitable driver found to mount mods/terrains/persiangulf/models/airfieldslightseffects/airfieldslightseffects.texture.zip 2023-10-31 19:23:53.518 ERROR EDCORE (Main): No suitable driver found to mount mods/terrains/persiangulf/models/modellighteffects/modellighteffects.texture.zip 2023-10-31 19:23:53.518 ERROR EDCORE (Main): No suitable driver found to mount mods/terrains/persiangulf/assets/assetstextures.zip Merci pour ton aide Flappie.

Hello , I believe that quad-view is available for few headset ( quest pro for exemple ) is anybody can confirm ?
