PR2 now launches again with latest Catalyst 14.1 drivers! Yay!
Whatever the 13.x drivers broke that prevented PR2 from launching properly appears to have been fixed with the latest AMD driver update, so if your Radeon card prevented you from playing this game, you can now give it a shot.

I'm on Win7 x64, Radeon HD 5670, running the 14.1 drivers.
