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) :)
Diablo IV definitely works in Linux. I played Sorc all the way to level 75 just fine. You can install Battle.net via Lutris, Bottles, or even directly via Proton Experimental in Steam and then install Diablo IV from there.
Oh, interesting! How is performance compared to running on Windows?
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.
