It’s comparable more often than not, but honestly even if it was 17% worse on average I would still stick to Linux and just build a better computer. Which is what I did before proton.
No doubt and I’m the same way, I’m just trying to say that one shouldn’t try to sell Linux solely based on “gaming performance” when it is definitely not the case most of the time.
Linux is not used like windows or macos at all, and new users will definitely be frustrated enough just learning to use the operating system. Believe me, I think it is awesome that we are finally getting another gaming revolution in the community (Linux gaming actually used to be pretty good before around 2010), but keep in mind that these efforts are for the community and steam deck users. Anyone who wants to have it too will ultimately have to join the community and learn the ropes.
