There's still room for improvement, but Linux gaming has come a long way in a short time.
I remember when Proton launched it was like magic playing games like Doom and Nier Automata straight from the Linux Steam client with excellent performance. I do not miss the days of having the Windows version of Steam installed separately.
The steam deck inspired me to finally ditch Windows for good. I have dealt with it for the past 15+ years professional and I grew so damn tired of it. Built myself a nice little gaming PC running pop is and I'm quite pleased!
Mac as a laptop, steamdeck for gaming. There is a Win 11 VM on my unraid server for the occasional poke at something but I can't say I miss windows in any way....
Same on the laptop and Unraid server actually, lol. But I don't run any VMs on it at all. Hardware is a bit old so I don't know how much it could run effectively.
