DLSS it can be only implemented in Vulkan or DX12. Not in DX11 !!! so Vulkan would come first than DLSS.

No solution for me. Its curious because with motion smoothing OFF I get sustained stable framerates (when Im not over a bigcitie... in these situation even with steam Index at 150% it stutters due the graphic card cannot sustain 80 or 90 fps...). If I put motion smoothing ON, I have many BIG stutters specially with many AI units. In ST motion smoothing is totally smooth.

Thanks. I have a problem with MT and Valve Index, it produces a los of stutters with motion smoothing ON. Seems very few people here with a Index, ... do you have fluid performance with MT and motion smoothin ON (40 or 45 fps limited)? Using OpenXR it could improve performance? Its quite curious beacuse I have smooth fluid in MT 2D, 120 fps on Gsync (4090 and 5900x). But in VR... single thread is fluid but MT-VR is a stuttering fest.

Thanks. Any guide to install it please?

Yes. I can confirm, I have it too in the latest patch. Huge FPS performance hit in ST near supercarrier and on the deck. Reverted to previous beta 2.8.3.37854.1, FPS are normal, no performance hit.

MT stutters a lot with Valve Index, any fix ??

OpenXR toolkit is compatible with Valve Index?

Didn't solve it for either

It seems to me that OpenXR under Native SteamVR HMD (like valve index) causes a lot of lag or stuttering, unable to mantaing 40 or 45 fps in many situations. Any help? Mods are removed. DCS log attached. Let me give to you my testes: VR-MT 80 hz (without motion smoothing), sustained. but with a lot of stuttering (spikes cause fluctuations 79 Hz - 80 Hz). Attach DCS log and some pictures. All CPU Bounded (doesn´t make sense) VR-MT 60 hz (with motion smoothing, Index at 120 Hz), sustained. but with a lot of stuttering (spikes cause fluctuations 59 Hz - 60 Hz). Attach some pictures. All CPU Bounded (doesn´t make sense) 2D (120 fps, 4K, Syria Big City, and GPU-bounded everytime - except the instant I take the picture -). TOTALLY SMOOTH AS SILK in 2D In ST version, in VR is smooth as silk (even in Syria I have 40 or 45 fps sustained in motion smoothing). Unplayable for me in MT version with my HMD. It seems that native SteamVR HMD are not going well with OpenXR. My spects: Windows 10, 4090, 32GB DDR4 3600Mhz, 5900x, SSD 2TB, Valve Index HMD. dcs.log

And what about SteamVR native HDMs like index? Performance in Index is not good under OpenXR Edit: 2D works perfectly in MT (120 Hz Vsync and GPU bound even in big cities and 4K). But with OpenXR (Valve Index) I have a lot of spikes, constantly CPU bound message, even at motion smoothin (40Hz) and low pixel density. In SP with Valve Index (native steamVR) I don´t have any stutters even in big cities, constant 40fps with motion smoothing.

I cannot start with --force_steam_VR in MT

I´m on 4090, 5900x, SSD 2TB, 32 GB, and have CPU BOUND even in free flight without units (even with motion reprojection ON). In OpenXR, cannot try SteamVR in MT.

I would also know. I´m using a Steam VR native device (Valve index) a lot of stutters with MT openxr

Here with my Valve Index performance in OpenXR, in MT, is a stuttering mess (even with motion smoothing on). Much worse that in non MT version. MT will be compatible with SteamVR?

Anyone has this issue? latest patch

Valve Index. Is there some sharpness shader like reshade but working under OpenXR?

It seems to me that STEAM VR no longer works in MT version. Even putting "--force_steam_VR" (DCS Hangs) Only works in OpenXR which is not good for me (Valve Index) SteamVR will be abandoned in MT? Any fix please?

bump. Anyone fix it? ED please look at it...

Many Thanks I would test it tonigh, but I´m afraid about break my logbook.lua for future updates (I have many user campaigns started... a lot of them). I will backup of course...

So no hot FIX patch is expected in one month??? Cmon ED this is a gamebreaking bug (I know, beta).

Its not working either in v2.8.2.35632. Was working ok with OB v2.8.1.34667.2. me_logbook.lui "fix" by user it doesnt work in 2.8.2

Same bug in 2.8.2. Cannot end user campaigns.
