Don't waste your time with them, honestly! You know that when AMD release the following months driver, the Catalyst 12.1 in a preview, they don't really want you to worry about the official new one. We know this, because this isn't the first time they've done it. The 11.12 driver is actually worse than the 11.11c driver that has more fixes in it.
The issue is that AMD have almost come to a point where they are just doing WHQL drivers monthly, simply because they said they would. It's great that they do it, but the issue is that the revisions of the WHQL that aren't WHQL end up being the better option and they can come literally days after the official one.
With it seeming pretty set that we're going to see the new HD 7000 series card in January, I can honestly understand why not much is going on with the last few sets of drivers. For that reason, though, they should just concentrate on releasing up to date drivers that fix stuff, more so than worrying about these WHQL drivers.
I really like AMD, I've made that clear so many times. The direction they take in some areas, though, confuses me. We're seeing more and more people ask why they're bothering with WHQL drivers when they release an improved BETA days later. Who knows? Ultimately, it doesn't really matter.
