It's a common misconception that Proton adds any overhead. It's just an alternative implementation. In some aspects it will be faster (and in some other probably slower) because the Linux kernel does things differently from the NT kernel.

I have not run any benchmark but I exclusive use Linux as my gaming platform. I don't play any multiplayer though and I think that's one aspect where Linux is behind. But for single-player stuff it's perfectly fine.

One thing though is that I have to filter out which games I buy by checking on ProtonDB their level of compatibility. But I can play major AAA games just fine.
