I'm playing on max 1080p and the first mission runs smoothly, but during the second the game crashes every couple minutes -- usually not long enough to get to a new checkpoint. It seems like a number of people have had this issue with Crysis 3, but I can't find any solutions. I haven't had this problem with any other games. I'm using Windows 7 Ultimate, the above GPU, i5-3570k, 16 GB DDR3 1600, Samsung 840 250GB, and HX 750.
