I've been having some serious performance issues when using the Quest 2 Link with my PC. Everything is an annoyingly low framerate, and many textures are super fuzzy and muddy. This is true as soon as I enable Link, and is pretty consistent across games. I tested using Star Wars: Squadrons, and I honestly didn't notice much of a framerate difference between Low and Ultra, so I don't think it's my PC.
Here's what I've tried with no effect:
Set Priority of OVRServer_x64.exe to realtime
Turned off supersampling in SteamVR
Downgraded my AMD GPU driver from 20.12.1 to 20.9.1
Nothing has helped, and sometimes the link will stop working altogether and not allow me to connect.
