I've experienced a huge fps drop after this update, it is almost impossible to play now, before it was 40-50fps, now its 10-15fps.. I have a very decent PC: i7-4770, GTX770, 16gb, Battlefield 4 on ultra settings is running very smoothly about 80-110fps. Im guessing, that this is just a temporary issue, but very frustrating one, I can't play the game anymore.
