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.
