Proton came into existence in the later part of 2018, I jumped to linux about half a year before proton came out, so probably closer to 7 years now.

Jump the ship, I did 6 years ago, before even proton was a thing when games worked witha lot of thinkering.

Nowdays you habe so many great games working you won’t mind a couple of games not working because of all the other playable games.
