OK, I did some test with source ... the map de_nuke has lots of fences to play with ... 1st you need to enable at least 4xAA before anything happens 2nd with 4xaa and TAA using SS (super sampling) there is a huge difference when walking around looking at the fences BUT this comes at a huge performance drop I got a 6800 modded to 6800GT and the game runs perfect at 2xAA and runs fine at 4xAA but 4xAA with SS-TAA is unplayable way below 30fps and with huge mouselaggs so when we talk about 6200 .... FORGET IT

This was discovered over at Tweaks R Us when the 91.45's were leaked about a month ago. And yes, it does work even with my 6800GS AGP card. Very nice stuff.
