Outside of competitive shooters, which is my favorite genre to play on PC, a lot of stuff runs well through Proton. And that’s an issue of the anti-cheat systems.
Linux gaming isn’t for everyone, I play what I can on PC and have a PS5 for other experiences. There are plenty of games I wish I could play, but I’m not interested enough to dual boot windows. I would do vfio passthrough for a VM, if they weren’t getting better at detecting that.
Ultimately I have enough games I can play to stay busy.
