ATI Radeon 8500 graphic problems?

Having some trouble with the ATI Radeon 8500. The graphics in some games are now much worse than they appeared when using my ATI Radeon DDR 32MB card. An example is zelda: With the 8500, there are many graphic errors in the intro (the dust behind the horse appears block-like, and there is a block formation around the moon). During the game, different 3D items appear the same, Block-like, and one dimensional? With my old Radeon DDR, the game looked next to perfect. If anyone has had this same problem, or has some solution to fix this, please help me out. Thanks. The link below is a picture of zelda with the blocklike formations, just so you know what I'm talking about.

Drivers

Yes, I do have the latest drivers. The thing is, my old Radeon card had the same problem, until I got an updated driver. So my guess is that the driver is the problem and until ATI offers a better one, my 8500 will remain in its box, unused. Thanks all for your input. Kief
