i have the latest driver from nvidia. Also updated the game to 1.50 1.51 still got the problem. It's quite annoying to see it, other games plays fine. I spend hours seraching online trying to find a solution.
Whenever I get this error I roll-back to the old drivers. Typically Nvidia's new drivers offer major stability/performance improvements for the newest cards (8800s these days) while totally screwing up older cards (7900gtx and lower). This is unlike ATI/AMD where their new drivers are better for everyone.
i had no idea that the omega driver is still around. I will take a look at that.
I did try older driver, but still the same error. I think it maybe the card is oc too high as I am testing the slightly downclock and it seems to run the game fine.
