like, why not nvidia fps counter, msi afterburner, or another fps counter? i dont get it

Because we know how that one functions and how we can use it for verification. I've tried to look at other FPS counters, but couldn't notice anything significant.

if it's for nvidia it will be only for people who have nvidia gpu and some of them r not in linux so the game is only in steam and everyone can use it (but still i hate it it's bad)
