I got PCVR working on Manjaro (my main installation is NixOS and I installed Manjaro to see if VR would work) on my Valve Index, but for some reason audio sounded like it was bass boosted a ton and games ran at 30 fps. IMO PCVR on Linux just isn’t there yet. The steam vr dashboard didn’t work at all either, might’ve been because of the new Steam VR 2.0 not prioritizing Linux use at all.
Not sure what the experience is like on quest, but I would think its not too far off from my Valve Index experience.
