Every time I open the app through SteamVR, or open the SteamVR menu in VRChat, there's a chance VRChat starts using 90% gpu and gets 2 frames per second. The computer specs are more than enough with a 2060 super and a Valve Index. It lags both in VR, and on the window displaying the game.
This has been happening so often that I broke down crying wanting to meet a friend, I wish I knew how to fix this. I don't know if it's VRChat or how SteamVR works with VRChat specifically, but there's always a chance it will happen when starting up or going into the SteamVR menu.... Or sometimes, it just doesn't let me start it at all without lagging like in the case for today.
