I’ve had the complete opposite experience for the vast majority of games, where in most cases performance for me has been better on Linux than it was on Windows (can’t compare like for like now as I no longer have a Windows install outside of a VM). Friends of mine experience weird mid-session crashes and hangs on Windows that I’ve never had on Linux. I’m running an Nvidia GPU which is supposedly some kind of Linux boogeyman, but have had only one issue with EDID of a specific monitor and that’s it. Just my experience YMMV.
