Agreed. For anyone interested in FPS boost, try glorious eggroll proton.

I personally compile it myself off the AUR with the -O3 -march=native flags (look at the PKGBUILD for more details), and I get fewer FPS than Windows, yet more consistently than Wine. No microstuttering.

My experience is that even running Among Us (i.e. a very simple game) via Steam/Proton on Ubuntu LTS (i.e. the most common platform) was quite fiddly. Didn't have chance to try much else, Factorio is luckily native
