I ran Linux Mint on a Lenovo Legion gaming laptop for 2 months.
Almost everything related to gaming worked but I did have problems.
Under X11 + Gnome, fractional scaling was pretty badly broken for some things, especially the Steam app. X11 + KDE fixed that issue.
Under X11 + KDE with hybrid graphics mode (automatically use APU for light tasks, dedicated GPU for games), the laptop's brightness controls were totally inoperable. I tried to research this but could not find a working solution. If brightness was problematic enough, I could pick one of the fixed graphic modes and log out and back in - mostly I left it near or at 100% and didn't touch it.
One game (Anno 1800) would not connect to multiplayer, but works completely under Windows.
Hogwart's Legacy ran horribly and was unstable in Linux Mint. It ran with much higher quality/performance and 100% stability under Windows.
Other games like ARK, Conan, Valheim, StarCraft 2 (using non-Steam Proton), Deep Rock Galactic all ran identically (from what I can tell) to Windows.
Also about 50% of the time, booting would hang for Linux Mint and I'd have to hard-reboot, probably pick an older kernel to boot into, and then I could reboot and go back to the latest kernel (a minor release under Linux 5.15). Fortunately rebooting is mostly infrequent.
Overall it wasn't quite in a state I was comfortable with, so I'm back to Windows 10, which is much better than Windows 11 (or much less bad?).
It's very rare for me to even buy a new game (unless it's a $20 early access game) but my spouse was very excited for it and I wanted to play alongside. (It's not multiplayer but we can still talk about the parts we've played.)
