This beta is a very old build, relative to what we have now. The beta is not indicative of what will be in Catalyst 11.1. It is targeted to the GPGPU / high end customers (think 12 monitors connected to 3-way Crossfire HD5970s or equivalent FireGL) who pour in $$$ and demand more heavily tested drivers so they don't get random kernel panics and stuff.
It's like when Red Hat releases a 5.x beta update -- my reaction is "um, OK..." because it provides no new features and maybe fixes a few tiny bugs or security issues. And corporations would rather pay for that stability / "known quantity" factor than use the latest developments.
Catalyst 11.1 will be using "old" code relative to the development trunk, but not quite as old as this beta. So you should see a really, really, really often desired feature show itself.
Is this the driver with the new Mono-based control center?
