Wait, I'm confused. The release notes to the 4.8s indicate that OpenGL performance has been significantly improved...but I thought that the 4.9 version of the Catalysts was going to have the totally rewritten OpenGL drivers.
Did they incorporate the OpenGL DLL from the 4.9beta into the 4.8 final, or is this a different enhancement? I'd like to upgrade my drivers to anticipate Doom 3 (whenever I get around to buying it), but I'd like to do it ONCE since I hate dealing with driver issue crap.
