Oh my gawd, this needs a bump! I just got around to getting this game again, and I have the same problem! I can't do diddly squat.
550ti with cuda and tonymac nvidia drivers!
Edit: Also, would this happen on an Nvidia 210 as well? I built a computer for my friend with spare parts, and I could trade out the 210 I gave him for my "better" card. I've already done it a few times before I got Lion, since 550ti didn't play nice with SL.
Edit edit: From what I'm reading, the 210 isn't Fermi, is it? Therefore it shouldn't have a problem?
