Crashes and Freezes during game play

Here's the crash logs, just freezes on a screen in multiplayer. Sound continues but I have to reboot to get back to windows. All appear to be similar.

I would try updating your video driver. Seems like I had that problem too with an older Nvidia driver. If you cant get it from apple just download the newest refrence drivers from Nvidia and do a force install.
