thanks for the response.
I checked without any mods in singleplayer and the problem is still there.
So it has nothing to do with the mods and on- offline experience.
Any other ideas?
the problem wasn’t the games.
I was playing something else and the same issues occured. After that, I checked my sounddevices and noticed something odd at the driver for my webcam.
Seems like the webcam was causing the trouble.
Since I unplugged it, everythings fine.
