Honestly, you don't even need Windows for gaming for the most part. 90% or more of the games I play run on Proton without any tweaking needed. The few exceptions are games which use anti cheat rootkits, games which I want to stream to my friends in discord (which doesn't pick up audio on Linux), and CP2077 (which doesn't seem to like ray tracing in proton).

I was very pleasantly surprised how smooth gaming on Linux is. I maintain a Windows 10 install and will for the foreseeable future, just for the odd cases where I need it. But I rarely boot into it any more.
