Built a new gaming PC a year ago, running on nobara.
Didn't even bother to pirate a Windows key for it.

No problems, everything just works 😊

Steam makes it extra nice, it just starts the game with what ever proton version you choose 🥳 

 Indeed - noticed the same; the Proton shuffle appears to be a thing of a past too 💪 

 I mostly run on the newest version, sometimes Experimental 😎

One game I wanted to pay, lost ark was rated as not working, but that's ok 😅
