frame rate is down

[barbiedoll]

I have an ATI x1650pro agp card and i to am dealing with graphic problems as well as i have the 7.12 omega driver installed the catylist won't work on my card for some reason. However, the game plays ok in the beginning but when u get closer to the end of the game when u reach the research facility after your done outside the game lags very badly, i had to quit playing cuz it was moving so slow even with effects turned off. Why is this and frictional should get this fixed and fast with a patch to be able to complete the game. otherwise what a rip off. I have windows xp sp2 installed and exceed min requirements.

Any help will be greatly appreciated. Thx in advance.
