It's been months since I've booted into Windows to play a game. Feels amazing. The only exception I've run into is heavy anticheat titles, like trying to play on Faceit CS2 servers.
I can live without that though. I don't think I'll bother setting up a Windows partition on my next PC.
I think the last time I had Windows installed was right around the release of Proton in 2018. Those initial releases were not great but the trend was very obvious.
There comes a point were you just don't miss it. The only moments that it is apparent is that disassociation you have when someone else just assumes you run Windows. I don't blame them, I am statistically the odd one there, but that is when you have to figure out things your way.
