In the second link, the image is much more clear and doesn't have the lighting problem with Nvidia cards in DX9. I have read on various forums that a lot of people are having this problem. If someone could link me to a place where it says an ATI driver has fixed this issue, I thank you, if not, here is the problem.
@TheMeanestGuest, I am not crazy, look at other forums and look at these images.
