Vortez.co.uk takes a look at the performance of the ATI Catalyst 10.4 Driver

There's a common belief amongst early adopters of new hardware, especially graphics cards, that performance will improve over time thanks to continuous driver updates. It's certainly a belief that manufacturers have tried to uphold themselves by constantly claiming performance improvements in their latest drivers. In many cases, their claims are correct since SLI and CrossfireX technologies are heavily reliant on software implementations and drivers undergo optimisations to take full potential of the hardware. Even with single card configurations, both Nvidia and ATI often claim major boosts of more than 10%, which is a figure that can often differentiate two separate cards (GTX295 vs HD5870). If those numbers are correct, it could essentially mean that relative performance differences between cards will vary over time and this has some interesting implications.
