Yeah, multiplayer games with kernel-level anti-cheat are gonna be real hard to support on Linux. I don’t know that we’ll ever have a good solution to that.

I’m curious: what feature(s) of SteamOS are keeping you from trying/switching to Linux?

If it’s Proton, you get that for free with any Steam install on Linux. I’ve been using it for the last couple years. (And it’s awesome)
