That’s a pretty big “just”, tbh. It would absolutely require the sort of proprietary kernel drivers most distros (understandably!) consider anathema, and I’m not sure game publishers want to shoulder that burden entirely themselves.

In one sense, the problem is "centralized".

Instead that there is a need to fix something special in many games, we can make many games working by fixing selected few entities.

EAC has already support for linux, so it should not be impossible.

There's definitely a lot games that don't run as well as they do on windows despite being generally playable on linux. It's nice to have a dual boot for games like that even if you play the vast majority of games on the linux side.
