This happens 2 times in differnet DayZ sessions but exactly at the marked position. It maybe NOT caused from DayZ. I'm running in the northern part of Zelenogorsk towards a deer stand, when suddenly my FPS went down to 0 FPS / 1 FPS. Audio is working but graphics stuttered/freezes for about 45secs up to 1min.
First time this occured, i stopped DayZ with Windows Taks Manager and when I immediatly re-joined I always stuck in 0/1 FPS. I tried to move away and when i got a little distance, FPS went back to my normal.
Second time this happend, it was the same position, but I just go on playing and as first time, after going forward some meters, the game went back to normal fps.
