Not well though.
In virtually every instance of gaming I've tried, Nvidia is measurably slower on Linux than Windows (where apparently that's not the case with AMD), with the sole exception being Java games like modded Minecraft and Starsector.
That, and (on my 3090 desktop) I still hold my breath wondering if Nvidia will make my setup blackscreen. And I'm not even using it for display out! This will continue to be a fundamental issue with the drivers closed source and separate from the kernel.
Point I'm making is, if gamers suddenly had to use linux overnight and reviewers benched it, AMD would suddenly appear much more competitive.
