Keep crashing over and over agian in BF4 Siege of Shanghai..

I`ve had the same problem. I found out that the map was just too big and too detailed for most low-mid range cpu`s (I had a a10-7700k), so I solved it by upgrading to a fx-8350. For the other people using i5`s it was probably a bug in the game itself not giving the engine to access all the cores, meaning you were basically playing with 1 or 2 cores.
