Same here, fellow Fedora and Windows dual boot. I have a seperate hard drive for kernel level anti-cheat games: Escape From Tarkov - some PVE maps do run under Linux but PVP and parts of the map require anti-cheat.

Battlefield games from 5 onwards

Call of Duty games Coldwar onwards - do not open a call of duty game under Linux, there have been posts where it is an instant ban.

Ghosts of Tabor

I do have hope that one day the anti-cheat situation will work out where it doesn’t matter what operating system you are running but for now if I want to play some of the above games with friends for now I dual boot.

This video maybe useful regarding the post installation for Fedora 39 for gaming. using the KDE spin https://fedoraproject.org/spins/ which is a bit more familiar for windows users. https://youtu.be/76OnnvIWEUk?si=j3ATMQYMHvSzBkc4
