Even though I’ve always run Linux in some capacity, I always kept a Windows gaming PC.
Fully made the jump to Linux gaming about 1.5 years ago, and haven’t looked back. Thanks to the awesome progress on Proton, I can play just about everything I care about. The primary problems come from games with specific anti-cheat engines, but I find those are the kinds of games I don’t really play.
Also finally switched from X11 to Wayland/Niri, and Wayland is finally stable enough. Better gaming performance than X11 as well.
Valve still needs to cut their dependency on Windows ecosystem, Proton exists while Microsoft Games/XBox decides it isn't something hurting their bottom line.
