Linux

You are using Proton I assume? I haven't gotten around to installing Linux desktop so I can't speak for much outside of my steam deck. But I haven't had any issues playing games other than not being powerful enough for most games on high settings. Even "not verified" titles usually run just fine and if they don't, like Recetear having audio issues, I just had to find a different proton version or something. Games with native support obviously worked great. I have heard that GeForce cards are a crapshoot on Linux though.
