Here is my MacPro:
Processor 2 x 2.26 GHz Quad-Core Intel Xeon
Memory 8 GB 1066 MHz DDR3 ECC
Graphics NVIDIA GeForce GTX 285 1024 MB
Software OS X 10.8.2 (12C60)
I have no performance issues whatsoever except for after patch 1.05 if I play for an extended (and really, a couple of hours isn't extended) period of time the screen freezes and then my mac crashes entirely and i have to hard reset.
Temperature is not the issue as my system and video card run well within standard operating temps.
Please help! This makes this great game unplayable and horribly frustrating.
