ATI Catalyst 10.3a Performance Test

The biggest game to improve here is DiRT 2. AMD claimed an "up to" 20% improvement on Radeon HD 5800 series video cards in this game. We are seeing here a near 13% improvement, which is very good for a driver update to provide that kind of a boost. Unfortunately this was the only game to provide such a boost, in Aliens vs. Predator we are seeing around a 2% increase, which is a bit lower than AMD’s claim of a 5% performance increase, which is all rather small to begin with. Crysis: Warhead was on the list, and AMD claimed a 6% performance improvement. It seems here we are only seeing half that, close to 3%.
