Far Cry 2, H.A.W.X, and basic summary
H.A.W.X
Interestingly, we see the larger gains at the lower resolutions, and the 10.3a performance is such that it matches the Radeon HD 5870's on Catalyst 10.2.
Summary
Our brief look at Catalyst 10.3a performance shows that ATI has found significant improvements in certain games - up to 20 per cent on a Radeon HD 5850. The cynic in us reckons that ATI's kept performance back, ready to be unleashed just before NVIDIA's prized high-end GPU, Fermi, is made available.
ATI's also promising an update to CrossFireX profiles that'll further boost performance in multi-GPU mode, too. You'll have to wait a short while to see where ATI's crop of DX11 GPUs shape up against NVIDIA's, which is also bringing performance jumps with its ForceWare 197.13s.
Newer, faster drivers are good for the consumer but they make testers pull their hair out with gay abandon at the thought of retesting a bunch of cards.
Feel free to download the Catalyst 10.3a drivers here and let us know how you get on.
