Annoying Textures and Spiking Graphics *Black Plague*

[rods]

I have read up as much as I could, I've uninstalled and installed the latest drivers for my video card several times but still no luck. I've tinkered with all the in-game options as well as catalyst controls. I have a Radeon 9600 pro, updated up to version 9.1 (the latest). I'm not sure what else I can do, but the textures in game sometimes, more often than not, spike through the wall and pretty much make some areas unplayable. Any help would be appreciated.
