I know, lame post, but I wanted to say that Linux gaming has gotten soooo much better, to the point that I honestly think my games are running better than on Windows. I’ve played so many games, but notable ones are Halo: MCC, MS Flight Sim 2020, Satisfactory, Mass Effect Legendary Edition, and right now I’m starting a full playthrough of Dragon Age.
Dragon Age is notorious even on Windows for being a pain because it’s such an old game. You have to install the 4gb patch, and even then it’s a bit rocky. Not on Linux though! I did have to install PhysX but I googled it and saw it was 2 buttons to install on Linux! Now it’s been rock solid and stable, with no crashes.
Linux gaming may have a high bar to learn, but that bar is constantly getting lower! Exciting times!
Good luck. My experience with vfio is that it works…ish. There are a lot of compromises still, depending on what kind of setup you really want. I’ve effectively said now that if the game doesn’t work on Linux (which now, like you mentioned, is anti-cheat-related), then it’s not worth playing. Windows Recall was enough to finally break me of this “Windows safety blanket” that I’ve had for 25 years of trying to game on Linux. With Proton and Glorious Eggroll’s ge-proton, everything effectively just works. And one day, all this anti-cheat nonsense will be a thing of the past.
I’ve done it in the past. It’s always a bit of work. But I really only need it for a handful of things at the most.
