Ok guys here is a solution of this Problem! (at first sorry for my bad english ;) ) Me and my clan g4m3.eu tried out diffrent things to find the reason for this problem. There are some items which has a buggy textrue. They are looking like the items in the picture in the appendix. if these items are lying on the ground and you will approach your fps will drop down! only if you move away from the point where they are lying your frames will go up again. The same happens if there is a guy who carries items like that with him. if he is in the near of you, your frames drops and if he will go away the frames go up again. hope the developers will fix it soon!
