For me, the global AA setting works, using either the control panel or nHancer. Any AA set in individual profiles, however, does not. I'm pretty sure it's the drivers, since I tried switching back and forth between these and the 186.18 and profiles would work flawlessly on the latter. It's a little strange, since the AF setting does work both globally and for game profiles. Apart from that, the switching between 2D and 3D modes is a little jumpy. Even opening Firefox (or just a new tab) makes the card switch into 3D mode for several seconds before it falls back to 2D clocks. Considering performance, the drivers seem to be fine, but I'm not playing any demanding stuff right now anyway.
