Beginning of last year. But then I wanted to 1) game in VR again and 2) play games with friends which contained anti-cheat software which wasn't compatible with Windows, so I spontaneously went back to Windows for these two things.

I'm someone who switches games pretty fast, I'm not one to play the same multiplayer game for a long time. So each time I started a new game, I had to debug in Linux to get it working.

Since January I've played Planet Crafter, Steep, Back 4 Blood, Bioshock Infinite, Atomic Heart, Hogwarts Legacy and now Elden Ring. No idea what percentage of these games "just work" on Linux, but I doubt that the experience would be the same as on Windows.
