You’re right (I hate to say it )
We have https://www.geforce.com/geforce-experience/download
GeForce Experience and then we have
GeForce Game Ready Driver.
C’est la vie.
What VR apps were you experiencing studders with?
Did you try uninstalling Nvidia GeForce Experience? or at least shutting down the 2 services via services.msc?
Never had an issue with pre-rendered frames set at 1 and I have been using that since early in the year regardless of SweVivers recommendation then to use 3
I find it weird I can run Doom 2016 via SteamVR Theater Mode and have all 4 cores of my powerhouse CPU thrashed with no issues what so ever yet I run Il2 with FFR and a little single core stress via AI or something and = Crash.
Maybe it is a DirectX vs Vulcan thing or something else.
Have been running FFR with PiTool render at 1.25, SteamVR both 100% on Normal FOV and Balanced Graphics Il2 with some success. More like 80 to 90% up time and even online with Finnish Multiplay server but if I go in to ground attack a heavily defended target - Crash.
Looking forward to the next Il2 update and see what that brings under the hood.
PiTool 18.104.22.168 - been great. Does need some polish with interface like Hz switching and so but on the whole.
