Lotta users == lotta bug reports, complaints, and motivated people.
Great example is CP2077, which just got a 2.0 release, and naturally has a lot of issues, with a few that are related to Linux. The one I got was related to not detected the keyboard well via Proton Experimental.
There was a workaround up on steam discussion boards in like < 1 week, and it's getting plenty of attention.
