I'm having the same or very similar issue to some other users here. I updated my video drivers yesturday to the new 314.07 driver from NVidia. I rolled my driver back thinking maybe that caused the issue, but the game still crashes everytime I run it. I've also tried verifying the game cache multiple times. Steam always downloads 11.9mb for Sam3 when it finishes the verification process. I do not have any antivirus stuff installed except for Microsoft Security Essentials, which has been present since before I got Sam 3. Anyway, here are the logs.
