It happens on Windows too? I thought it was just a Linux kernel issue. My last monitor was basic as can be, but it conked out when I updated my OS and was replaced with a low end gaming monitor. Since then, I can only play a little while before the graphics get super choppy whenever I move or look around. And before a gaming monitor, I could leave the game running for DAYS without an issue.
Guess they need to make the game actually playable for people. Again.
