Yes, your way is the correct one. I can run MAX settings everywhere now in DCS (except for visib range at high, and high clouds (not ultra). And the most important : Multiplayer is good now, smooth as single.

I tried, and thank you very much, it is waaaaaaaaaayyyyyyyyyyyyyyy better than before. I don't know why the f*ck if I play with Render Quality parameter on PimaxPlay, once in DCS it starts to stutter again ... But if I uninstall everything except DCS, and reinstall in the order you presented above, it works, it rocks better than before. I'll try to find the best balance/compromise, via the settings.cfg on user files' QVF folder. DCS in VR is a SCIENCE.

Cool mate What's your Rig's specs ?

I freshly installed Win 11 Pro in 24H2. I tried : -PimaxPlay last version and natively integrated QV off, at 1.00 PD -QV Companion It's an horror. DCS has never ran so badly. Stutters... Tomorrow I'll try from start all your suggestions and what you advised to me, I hope to get again a very nice quality, no stutters, and for Christ sake, smooth experience on Multiplayer servers. I'm about to give up. Seriously Eagle Dynamics...

I finally found where was the problem : I didn't tick the QuadView case in DCS VR settings. I tried. The gain is not as much as I expected... In this case you must deactivate OXRTK with DCS QV activated. I get back with last Pimax Client 1.35, deactivated OXRTK, activated OpenXR within Pimax Play, and it seems to be a better experience (than Pimax 1.29 with PimaxXR/QVF/OXRTK), which is not so bad (I admit it) but not incredible as I can read on forums.

I installed QuadView after OXRTK, but I'm not sure if everything is correctly done. In the QV folder in user files, there are two files. One "Quadviews-Fixed-Foveated.log" indeed, which contains : 2024-12-26 20:00:46 +0100: XR_APILAYER_MBUCCHIA_quad_views_foveated layer (v1.1.3) is active 2024-12-26 20:00:46 +0100: Using layer: XR_APILAYER_MBUCCHIA_quad_views_foveated 2024-12-26 20:00:46 +0100: Using layer: XR_APILAYER_MBUCCHIA_toolkit 2024-12-26 20:00:46 +0100: Using layer: XR_APILAYER_FREDEMMOTT_OpenKneeboard 2024-12-26 20:00:49 +0100: Cannot satisfy implicit extension request: XR_FB_eye_tracking_social 2024-12-26 20:00:50 +0100: Requested extension: XR_KHR_D3D11_enable 2024-12-26 20:00:50 +0100: Requested extension: XR_KHR_visibility_mask 2024-12-26 20:00:50 +0100: Requested extension: XR_EXT_hand_tracking 2024-12-26 20:00:50 +0100: Requesting extension: XR_EXT_eye_gaze_interaction 2024-12-26 20:00:53 +0100: Application: DCS (DCS.exe) 2024-12-26 20:00:53 +0100: XR_APILAYER_MBUCCHIA_quad_views_foveated layer will be bypassed And the "settings.cfg". I think there is a quirk...

I think I'll go right way with QuadViews. I installed it, defaultized OpenXR etc... But, any tip about settings.cfg ? Maybe you could share the content of yours ? Thank you much mate, I appreciate

Hey Wipeout, thanks a lot for answering So, I'm not using FFR (should I ?). What is OXRTK ? OpenXR Tool Kit ? Yes, I'm using it. Turbo Mode, without any Fixed Foveated Render (don't seems to be better or worse with or without it). Running 64 Hz on Pimax client 1.35.02.01, and no FPS limit (300 IIRC) on last DCS standalone version (updated each time) from ED website. nVidia control panel set at Performance on power settings. Should I disable HAGS and try ? I have a 7800X3D, yet not considered as a bad CPU for our cherished DCS. For what I think actually, It's probably since the 1.30/31 versions of Pimax Play client where things get worse ... Thank you very much for your observations and your help

Good Day all Is there any serious guide (BIOS adjustments/DCS settings/nVidia configurator settings/ apps ...) to optimize things with a Pimax 5k Plus ? 7800X3D / 4090 SuprimX Liquid / Trident 64g DDR5 5600 / Win11 Pro I'm only finding things about same specs rigs BUT with Pimax Crystal, and I don't want to buy one, I prefer to wait for the Super version. Since last DCS updates (maybe 3 months ago) my experience seems getting worse each update. I'm starting to boil inside.
