For the screenshot I pinned the game to the cpus 3,7 with taskset to stop it
from polluting the graphs so much when jumping between cpus. Didn't really
decrease or increase the performance much.

I really don't know right now... When the game loses the input focus, it pauses
the game and the game rendering itself is not updated anymore I think. The cpu
usage will drop from 112-114% cpu usage to 100% cpu usage and the fps go up to
60 fps. When the game is focussed again, it unpauses, and then it's again low
performance.
