I literally only use Windows for games. And I guess now RealityScan which is gaming adjacent.

If I had the confidence that I could play a new release on Linux day 1 without trading an enormous amount of performance, I wouldn't need Windows at all.

Depending on your hardware and gaming needs, the current state of Linux gaming may already be enough.

I run Arch with an Nvidia GPU (which historically had poor Linux support compared to AMD), and I’ve been able to play 100% of the games that I used to play on Windows with no noticeable performance decrease.

There is one significant issue with Dx12 on nvidia, but even that has been root caused and should be fixed next year.
