I still have to keep Windows around for (ironically) performance reasons.

Some sim games like Rimworld and Stellaris just have a big hit on linux for me, native or Proton. And in a sim game, that means slow turns and stutters you can’t avoid instead of slightly lesser graphics. And it’s not sublte, native stellaris is like a good 30%-40% slower with even higher spikes last time I benched them back to back.
