I use Linux on my gaming machine too. If a given title won't work in WINE/Proton, I can live with that... there are more than enough that work perfectly to eat up every minute of free time I have. Every thing I have really wanted to play has worked perfectly. I had that PC set up as dual boot from the moment I bought it (it's a laptop), but I finally gave Windows 10 the boot a few months ago and reclaimed the space for Linux. Can't say I miss Windows at all.
