    Using Reverb G2, constant dropped frames :(

    To add to the mix, it seems that WMR developers may have identified a performance bottleneck between SteamVR and WMR. See the link below. https://www.reddit.com/r/WindowsMR/comments/lmyusg/windows_mixed_reality_for_steamvr_updated_12536/gny2b6p?utm_source=share&utm_medium=web2x&context=3 Hopefully, things might improve when this issue gets sorted out. Steam and Microsoft seem to be working on it.

    Just to add my findings, having tried hours of suggested solutions - I found that biggest improvement was when using the nVidia Studio Driver (461.40). I think the issue is possibly driver related, but I've spent too much time already on this and, as has been mentioned, I think it might be time to move along to another sim as Codemasters are no longer working on it. It's real shame, DR2 was by far my favourite driving game. Onto PC2 or AAC perhaps.

    Further to the above - it is possible to get decent performance on a 3090 with G2 and Dirt Rally 2.0! Just need to figure out how - see the vid below...

    Hi, Similar issue here. Intel i9-9900KS, NVidia MSI Suprim X 3090, MSI MEG Z390 ACE mobo, 32GB DDR-4000 C19 memory, 2TB EVO Plus NVMe SSD. Using a relatively fresh install (2 days old) of Windows 10 Pro. Previously used an HTC Vive (original) and had everything on Ultra, with no issues. fpsVR Report: App: DiRT Rally 2.0 HMD: HP Reverb Virtual Reality Headset G20 (90.001 Hz, IPD 61.7) GPU: NVIDIA GeForce RTX 3090 ( CPU: Intel(R) Core(TM) i9-9900KS CPU @ 5.1GHz Delivered fps: 89.15 Duration: 38.9min. Headset was active: 33% GPU Frametimes: Median: 5.4 ms 99th percentile: 6.6 ms 99.9th percentile: 7.1 ms frametime <11.1ms(vsync): 100% CPU frametime: Median: 3.7 ms 99th percentile: 5.2 ms 99.9th percentile: 7.4 ms frametime <11.1ms(vsync): 99.9% Reprojection Ratio: 0.8% (for Index/Vive/VivePro headsets only) Dropped frames: 691 or 0.3% (for Index/Vive/VivePro headsets only) Max. SteamVR SS: 100% Render resolution per eye: 3160x3088(by SteamVR settings, Max.) (HMD driver recommended: 3159x3089) The Dirt2 Rally Steam VR graphics settings are at their lowest. CPU usage averages 10% with a short peak of 45%. GPU usage sits at about 62% with a short peak of about 76%. It's all well within limits, I'm getting very nearly perfect 90fps indicated yet I regularly get stutters in game. In game, fpsVR manifests these stutters as purple 'spikes' in its GPU frametime graph, and I see a stutter. It happens regularly and is easily repeatable. But the game sees 89.15 fps average with the longest frametimes at 7.1 and 7.4ms, which should be a complete non-issue and not noticeable, but fpsVR records 691 dropped frames after 40mins play. In game though, it's like someone pressing pause for a tenth of a second, really throws off the immersion and is enough to cause accidents! I'm using nVidia drivers 461.40 which to my understanding should have incorporated the VR stuttering hotfix driver 461.33. Suggestions elsewhere have said this might be an issue with reprojection settings, but I'll try the DX12 fix mentioned above. Any suggestions welcome.
