And they seem to work very very well here. I can't post number because I don't know how to enable an fps counter but on my Radeon9700 Pro AMD 1.6ghz rig (which should be HEAVILY processor-dependent) I could swear it runs 10-20 fps faster at 1024x768x2AAx4AF.
While I wasn't really satisfied with performance already from the start (eyeballing 35fps average), I'm really satisfied now. Gonna play some more to see if it really holds during fighting scenes.
Edit: Hmmm, others aren't experiencing huge performance gains (5-10 fps). So maybe Ati's marketing department tricked me here.
