I've been debating making the switch for a long time, but after spending like a week researching Proton, Lutris etc. on Linux, I decided to try it out and nuked my entire Windows 11 drive. :)
So far, every game I threw at it works perfectly fine, including Elden Ring & Cyberpunk.
I had to spend a little time troubleshooting some small issues but it's part of the fun!
Specs are in the neofetch, my compositor / WM is Wayfire (Wayland) :)
It seems to work great at least in my experience on Manjaro. Lutris is also great at what it does and makes the setup relatively easy.
