I hope that the graphics card is not the issue here. According to the requirements from the product page shows: ATI Radeon HD 3850 512 MB. I don’t know much about how the numbers on these cards work, but I assume that a larger number means a better video card. :shrug:
I’m actually more disappointed with the fact that there isn’t a “native” Mac version. The executable that downloads from Steam is a Linux executable. I have to wonder if the problem with the game running has more to do with the fact that it’s not a native Mac executable.
