It really has gotten pretty good. Unless you are playing some AAA that was just released or had a huge patch or something a lot of games "just work" in proton now. (Thanks Valve/Steam). From the post: >>This time I’m really going to do it. I am going to put Linux on my gaming PC. Calling it now. 2026 is the year of Linux on the desktop. Or at least on mine. Linux has been a perfectly viable desktop OS for ages. But gaming on Linux is now viable, too. Valve’s hard work getting Windows games to run well on the Linux-based Steam Deck has lifted all boats. Gaming handhelds that ship with Windows run better and have higher frame rates on Bazzite, a Fedora-based distro, than they do with Windows. And after reading about the upcoming Steam Machine and Antonio’s experience running Bazzite on the Framework Desktop, I want to try it.
