I've only played a few rounds today but so far I've had no issue. OpenSuSE Tumbleweed with AMD for graphics and CPU, and Plasma with Wayland for the DE. Don't remember which proton I'm running, either Experimental or GE I think, I'll have to check

I played for a couple hours yesterday with no issues. My frame rate actually seemed better.

Pop OS, AMD CPU and GPU.

The devs changes their kernal level anticheat from... what was it netgaurd? And replaced it with easy anti cheat.

I assume this was done because easy anti cheat is bettet at collecting data to sell to AI firms. And the old one was not. The attacking modders thing is the deflection.

Devs said it won't and to report linux issues on their official Zendesk. I heard this via a YouTuber that covers the game.
