So I just grabbed the new drivers for my 4850 and I'm seeing something odd in the Catalyst Control Panel. In the older hotfix drivers, when you went to the AntiAliasing section, there was a checkbox saying "use application preference" and a dropdown box, which had the filter options "box", "wide tent", "narrow tent", and "edge detect". So, I decided to play with edge detect a little bit, loaded up the new catalyst panel, and found a difference. That being, if you uncheck "app preference" it removes edge detect from the dropdown! Meaning, if you want to manually set the AA level, you no longer have the option of edge detect. Really Annoying.
