Game "Hangs" for a second when

[Hrothgaar]

Hi all,

I hope someone has an idea on how to fix my issue:

When I move around, the game "hangs" shortly (fraction of a second).
After it runs again, I look into totally different directions if I had pressed a directional key before.
This leads to getting disoriented a lot when moving around as these stutters happen a lot :-/

I got the impression that it could have to do something with the light-source problem people describe in other posts but my "stops" of the program are very short and my fps is fine.

I really hope anyone has a fix for that issue :-/
