Okay was having massive graphic slow-down issues which lead into a CTD of the game.
Updating graphics drivers has stopped the slowdown, but the game is STILL crashing.

No errors, just CTD. looked at the memory log, doesn't seem to be anything obvious like a memory leak or anything. Anyone know any solution to this or has anyone got the same problem?

running an i7 3930, radeon 7970. New graphics drivers are 13.200 BETA drivers, was running the original drivers but the latest BETA drivers seem to have fixed the slowing issue, but not the crashes.
