I've been gaming on Void Linux of all things since November and it's run everything that isn't just flat out incompatible with Linux (anti-cheat doesn't allow, etc).

Sometimes I think it sucks that I can't play X because the anti-cheat won't allow it to start, then I remember it's a kernel level driver I cross my fingers and hope isn't doing anything nefarious and feel better.

Same - I switched to Pop!_OS last year and after a decade or two of being disappointed with the claims that Linux gaming had come a long way, I'm very impressed with Valve's Proton compatibility.
