While I’m very much in a similar boat and 99.9% of my time is spent on Linux of some description, I do want to offer a warning to those who are tempted to make the switch:
Many games with an online multiplayer component rely on kernel-based anti-cheating software, which often doesn’t work on Linux (it could, but many devs don’t bother enabling it… it’s a big discussion point on Linux reddit). So if you’re big into your online multiplayer games, double check whether it’ll work before you go to the effort of moving everything over.
ETA: If you want to check compatibility between your steam library and Linux’s Proton, you can link your steam (or simply enter your steam id) here: https://www.protondb.com/profile and it’ll spurt out your Steam library and ratings of compatibility (including those impacted by the aforementioned anticheat problems).
