Yes - tried that too. However, the problem isn't with starting up in VR or in OpenXR in MT. The issues arise once i'm in DCS in MT in VR. 1 System specs: i9-11900KF OC to 5500Mhz with water block- MSI RTX4090 OC - ASUS ROG HERO VIII - 64GB DDR4 @3600MHz- 1TB SSD OS - 2TB SSD GAME- 1000W PSU Pimax 8kx - TM Pendular Pedals - TM Warthog Throttle - TM Waterhog HOTAS - TM F/A-18 Grip - WinWing Pheonix MIP/UPC - Homemade Landing Gear control.

Dave317 Posted March 10, 2023 Posted March 10, 2023 It's not just pimax. I'm using a reverb g1 and the shaking/stuttering is terrible. Completely unplayable.

It doesn't happen with the standard Single-Threaded bin\DCS.exe - i've tried clearing shaders, messing with OpenXR Toolkit settings, Pimax Settings, and nothing helps. I wouldn't even call it micro-stuttering, it's more like gatling-gun stuttering. I have hyperthreading enabled in bios, but my 11900KF only has 16 threads (2 per core) anyway. 1 System specs: i9-11900KF OC to 5500Mhz with water block- MSI RTX4090 OC - ASUS ROG HERO VIII - 64GB DDR4 @3600MHz- 1TB SSD OS - 2TB SSD GAME- 1000W PSU Pimax 8kx - TM Pendular Pedals - TM Warthog Throttle - TM Waterhog HOTAS - TM F/A-18 Grip - WinWing Pheonix MIP/UPC - Homemade Landing Gear control.

AMBUSH Posted March 10, 2023 Posted March 10, 2023 The issue seem to happen when the multi-threaded system becomes GPU bound. I have used OpenXR Toolkit to impose an FPS limit of 70 FPS (my PIMAX 8KX is older and only does 75hz) With that FPS limit setting the menu screen is stable and does not devolve into spinning views. I have loaded in multithread and played singleplayer and connected to two online servers and all was stable Reporting to ED and continued investigation is needed to find the root cause but that appears to be be a usable workaround at the moment 1

I'll give this a go and report back. I updated the firmware to run the 90Hz native so, following your lead, i'll set a cap at 80Hz in OXR Toolkit and see what happens!

GayCavalier Posted March 10, 2023 Author Posted March 10, 2023 OK.. problem solved! In PiTool, when you start the bin-mt\dcs.exe with force_VR and force_OpenXR arguments, it creates a new item in your PiTool>Settings>Games>Game List drop-down. The original "DCS World Steam Edition" is there, but now there's another one, simply called "DCS" within this settings page, Smart Smoothing was turned on by default, along with "vertical sync" set to 1/2, and Hidden Area Mask Enabled. TURN ALL OF THOSE OFF!! I restarted DCS MT, and I now have 59-60Hz at 4K native per eye, with high settings on, and good shadows etc.. i used to get 35-40Hz before. I am overjoyed! ..oh.. the loading screens are still a buggy nightmare, but now the VR experience in sim is working much better than before!

kamao Posted March 11, 2023 Posted March 11, 2023 Similar situation here, 4090, 5800X3D, OpenXR, DCS MT Standalone. Limiting FPS in OpenXR Toolkit will absolutely stop the 'shakes', but I need to lower it to around 40-50fps (where FPS counter shows CPU bound instead of GPU bound) to reliably stop the glitching. As you bump that number up it gradually gets worse. Looks to be a few other threads around MT CPU Bound/Bottlenecking, so hopefully it's on the radar!

Dgpm Posted May 7, 2023 Posted May 7, 2023 Same problem here. Menu shaking, no splash screens, when any mission starts textures are not loaded and take seconds to load. At night when you fly close to cities you can see smooth rays all over the place. Some times also you can see a blue circle arround you. Kind of nightmare. Try Turbo mode, limiting fps. On Pitool no smart smoothing, no hidden mask, no "vertical sync".

Temetre Posted May 12, 2023 Posted May 12, 2023 (edited) Oh yeah thats a very common and normal issue. When loading screens are on, your hardware might be so busy it cant really render the screen at any realistic framerate. Thats not a problem on flat screens, because theres no head movement and its not filling up your entire view. Let alone how ASW/smoothing/reprojection can make it even worse. But in VR, its extremely irritating and kinda painful, if they are so bright. Gotta close eyes. Would be nice if there was some way to have eye-friendly VR loading screens!
