"SteamVR for WMR" has its own reprojection mode. I think it was introduced recently. It's independent from the Microsoft WMR one. So in the end you have actually have 2 separate methods: one built in to SteamVR and another built in to WMR environment. If you run them both you get stutters. So enable SteamVR but disable WMR one (via the defaultvr.settings the file). Yes, I'd replace // with a #, which is a universal 'comment' symbol.

in case of VR players are looking through this thread. Ever since the update the stutter near the ground when looking over the wings was constant no matter the graphic settings, SS, SteamVR resolution, etc. The culprit on my system (5900x, 2080TI, G2): motion smoothing enabled in both WMR and SteamVR It wasn't a problem in DCS 2.56, and it's not a problem with IL2. But DCS 2.7 is picky about it apparently. 1) enable reprojection/smoothing in SteamVR 2) go to file steamapps\common\MixedRealityVRDriver\resources\settings\default.vrsettings and remove or comment out the line "motionReprojectionMode" All the stuttering near the ground is gone. Now it's all about maintaining the basic frame-rate with textures, msaa, hw, etc..

I just resolved a massive stuttering issue on my rig (5900x with 2080Ti and G2): Make sure you do not run WMR and SteamVR reprojection/motion smoothing together. It wasn't a problem in DCS 2.56, and it's not a problem with IL2. But DCS 2.7 is picky about it apparently. 1) enable reprojection/smoothing in SteamVR 2) go to file steamapps\common\MixedRealityVRDriver\resources\settings\default.vrsettings and remove or comment out the line "motionReprojectionMode" All the stuttering near the ground is gone. Now it's all about maintaining the basic frame-rate with textures, msaa, hw, etc..

maybe it's an issue with the order of launching WMR and SteamVR? On my rig if WMR is already running (right after the boot) and I launch "WMR for SteamVR" in Steam then tracking is all messed up, the picture moves with my head, etc etc. In order for it to work I have to kill everything (WMR,) then launch "WMR for SteamVR" app in Steam, which in its turn launches WMR and then SteamVR. For other people it was the other way around for some reason. My point is try the different launch orders, it may be as simple as that. Maybe.

I think what makes it weird in VR are the cloud reflections. In the sunny non-cloudy day the water looks great with 2.7. But as soon as there are clouds and it's overcast the water looks like a polished table top that somehow reflects everything there is in the sky.
