Why the fuck did I get an AMD card... They still haven't patched that?
Your mileage may very. The game is still temperamental when it comes to certain (and many, apparently) hardware configurations, but it's entirely possible that you'll be able to play the game just fine. Update to the latest drivers, don't force anything via CCC, set the game's texture cache option to "large", and take note of the final part of the OP here (titled "Blurry Textures and Texture Popping"). Best of luck!
