I forgot to mention, I did uninstall the game. If I run the game unpatched, it's fine. When I upgrade to the latest patch and enable SM 3.0, then I get the corruption.
When I last ran the game, I already had the X1900 installed, the 1.33 patch was loaded, and I already had SM 3.0 enabled. Everything was fine.
Now, it's garbage.
