Admittedly I now dual-boot to Windows to play videogames, but that's not because of faults in native Linux games, just the reduced selection.
Plenty of people on protondb reported zero issues with the same games on their Manjaro/Arch boxes.

Maybe it's the type of games I play, but this is extremely rare in my experience. I don't remember the last time I had to fiddle with anything outside the game's own settings despite having a multi-monitor setup.
I ran Manjaro for about half a year recently, including using it for gaming. Very few games actually worked out of the box for me, including games with so called "native" Linux support.
I ran into multiple games with "official" Linux support that were simply broken or became broken by an update. Some of those that weren't broken had significant performance issues (that Windows on the same machine didn't have).
Is it possible to game on Linux? Yes. But at the very least it requires fiddling. As much as I love Linux, gaming is just a lot easier on Windows.
