Starting today, the game is freezing for about half a second every 5 seconds. I'm pretty sure this wasn't there yesterday, or any day before during my 200 hours playtime.
The same thing occurs on any graphic setting, in the game menu, in the title screen and when the game is paused. Same stutters and same time interval.
