Risc,
I have the same Video card, same OS, and same problem. Misery loves company. If I find an answer I will make sure and post it back.
BTW what version are you all running of CM. I just got mine the other day, and it lists itself as v1.02, so I have not installed the patch, is this a correct assumption?
It is a shame. The game does list itself as win200 friendly, and I had no problem with the demo.
