>didn't know until know that my Quest 2 was playing PCVR games at 90fps instead of 120fps because I only had enabled it in the AirLink settings but not in the headset itself
I ran a quick performance test and I have a solid 120fps with 15-20% headroom on Into the Radius. I hope that's enough for the forseeable future, I got a 3060Ti in late 2020. But to be fair I didn't notice I was at 90Hz until I played Thrill of the Fight so I guess 90fps is fine for the majority of games.
