Im at a similar place as you where I do as much gaming on linux as possible but then there are some games that just do not work :(. At this point Im really thinking about playing warzone on a console since there is support for keyboard and mouse (last time I checked).
I used to kinda complain about this but being unable to play lol or lostark has greatly improved my life. I don’t mind being unable to play these games.
I am very grateful for proton and all of the technologies that allow me to play majority of my games. linux gaming in 2015 was painful.
