I have (had?) A win10 machine for gaming with a nvidia 1080 for the past ten years since gaming wasn’t performant enough for me on Linux. Nouveau wasn’t cutting it fps wise and the nvidia drivers were a nightmare if you dared to alt-tab or expected more than 20fps.
I bought a mid tier (radeon7600xt) from AMD and it was (I am not kidding) plug and play. And I don’t mean the Microsoft blue screen presentation plugnplay.
Natively I got performant 3d fps (glxgears must be celebrating its 100th birthdaynow) and thanks to valves wine fork it was even easier to get more demanding games up and running. Before icouldn’t even run portal.
Thank you AMD for doing something right where nvidia is obviously screwing up.
It might be edge cases. I’ve played games on proton just fine with my 1060 and now my 3070. Doom eternal, Tomb Raider, Hitman, Cities Skylines, Guild Wars 2, 7 Days to Die, a whole range of games.
My 960 didn’t work at all, and I had to dual boot windows to play any game. Most Linux distros didn’t boot, even.
I never managed to eliminate tearing though.
