TweakTown checked out the new Catalyst driver, you can check out the Windows 7 performance figures over here.
"I knew this driver was going to come, but I have to admit I was a little worried that for the first time in a few years AMD might just miss it. Of course they didn't, and today we're looking at the latest version of the Catalyst drivers - the 11.3s.
The thing is, though, it's pretty clear that AMD don't care about this driver a whole lot and instead it's only here so they don't ruin their perfect record. That's fine, because it means I don't ruin mine either with the Catalyst drivers, but with no performance improvements being mentioned in the driver and AMD instead choosing to put more emphasis on the next iteration, it's clear that this is just a filler driver."
