Not me! I switched in 2017, right around the time Windows 10 "telemetry" (read: spyware) was getting backported to Windows 7.

It was a rough first couple of years, gaming-wise, but I managed to get by playing mostly Linux-native games and using PlayOnLinux with pre-Proton WINE for the one or two games important enough to justify the hassle.

(INB4 "weird flex but OK")

I gotta admit, I was pretty conflicted about Proton when it was first announced, since there was a lot of fear that it would reduce developer impetus to make proper Linux-native games. I'm not actually sure whether that came to pass or not, but I feel like the issue is a lot less important than it seemed at the time.
