I'm somewhat lucky in that I didn't have to be the one to force that issue, another friend in my gaming group already made the decision that he would switch to Linux and no longer play any games that did not work on Linux/Proton. So it was pretty easy for me to just switch last year.
My thinking was that I’ll use the Steam Machine for whatever I can. If there’s some title that friends really want to play and that requires kernel anticheat, and it exists in geforce now, I’ll do that from the steam machine.
If it’s something even less doable than that… well I’ll do without.
