Hello Feedback Tracker,
as I now discovered a little new DayZ feature, this game will drop it's FPS on OBS (and only in OBS) instantly as i'm using OBS.

Since active DayZ program tab the FPS is droping to 15-20fps. It could be a problem with flora since in woods and forrests the fps drops to the mentioned value but in citys it behaves mostly on normal fps stats.
