This driver set is a bit all over the place. For the most part performance seems to be up, which is always a good thing. The particularly good news is that there are performance improvements seen in the more important minimum department. This is where we want to see the increases which hopefully help in going above that golden 30 FPS minimum we always like to see.
But as we mentioned in our test system setup comments, the performance gains were promised under CPU-limited applications. Since this isn't really an issue for us, the gains were probably not as great as they would have been if we did have this problem.
With that said, people have reported good gains all over the place which is excellent news for people with higher end graphics cards and lower end CPUs, or simply those who aren't interested or don't know how to overclock their CPU.
With the general line-up of fixes, this is one of the best gains we've seen from an ATI driver in ages. It's not enough to knock NVIDIA from the top spot, but for ATI owners a bit of extra performance is always appreciated.
It's safe to say with the good gains we've seen today that the next driver will probably be more orientated around bug fixes.
