I keep trying to play steam vr games and they load up fine but as soon as I get in the actual game it lags and I get 2 fps. If I wait a bit it will go back to normal but then the next few steps I take it does the same thing. The only exception for this is beat saber which works fine with steam vr and all oculus store products that I've bought work fine. I've tried nearly everything, please help.
Impossible to say for sure. Maybe reinstall SteamVR or at least make sure you are not in a beta version. You are probably best to contact Steam Support for help. Maybe they can look at your logfiles and make some suggestions. Good luck mate.
