For several days now i could not complete Crysis 3, after beating the alpha ceph my game kept crashing after trying to free psycho from the vtol, i got a white screen and then a black screen and then just as prophet is dragged away i get a crash with a message in windows telling me to close Crysis3. Today i decided to play Crysis3 offline in Origin and i set all my graphics setting to Very High, aa was set at smaax1, 16x anisotropic filtering, motion blur high, 1920x1080, and i was able to complete the ending. This is strange, but it worked for me. The ending is quite good and some are missing out on this.
