Steps:
1. It appears to happen while the game is out of focus, irrespective of whether "lower gpu utilization when out of focus" is ticked or not, the AFK option is also not ticked.
2. The problem is very visible when it occurs, because the game runs like a slideshow whether in focus or not; interestingly I did once experience cutscenes in castrum meridanium run well, but gameplay at 1 FPS

GPU performance change before and after you started having the issue: No real difference when it works; drop from 90-110 to 1-5 when the bug occurs
