ATI added some cool features to CCC, particularly for the Video enthusiasts out there, and have all but eliminated the unresponsive interface. Load times are still a bit long, but they have improved significantly over earlier CCC releases. As well, the memory footprint has been reduced quite a bit. Instead of having two CLI processes running that each took a sizeable chunk of system resource, there are now three that, total, take quite a bit less.
The performance improvements for the games that ATI mentioned in their release documents are pretty good. The most impressive improvements came with Halo and Riddick where both games got quite a big boost in performance. For the more popular titles like Half-Life 2 and Splinter Cell 3 there are virtually no performance increases but to be fair, for most of the games and apps that ATI cited there were some fairly significant speedups.
What's most interesting about this release is that ATI has come out and told us what to expect down the road. As far as I can remember ATI has never really put future feature additions in stone like they have here today. I have no doubt that the new stuff will come but should things start slipping, breaking these "promises" to users will undoubtedly hurt them a lot, especailly when you consider all the negativity they've had to endure over the last year or so.
