SteamVR became unusable after recent updates. I updated PiTool (188.8.131.520) and installed Pimax Experience from official installer.
After this I am unable to use SteamVR home. It lags incredibly. I tired to change render quality to lowest (0.5) in PiTool but nothing changes.
Pimax Experience runs fine though.
I noticed my GPU consumption goes to 100% right after I run SteamVR
I have RTX 2060, i5-9700, 64 GB RAM. I had no issues running it until now.
Did you have similar issues? Maybe the recent update adding 90Hz support somehow broke it for users of less powerful GPU’s?
EDIT: It’s not only SteamVR, I see big framerate drops almost in each game.
