The premise of this mod is that the FireGL drivers are highly optimised for OpenGL so will therefore provide massive boosts in OGL games. Problem is they are optimised for OGL workstation apps and therefore lack the full in-game functionality of the consumer-level (Catalyst) drivers.
Sure, you might get higher benchmarks scores, but the game will be rendered incorrectly - probably with very serious visual glitches.
