As you may or may not have heard, ATi is going to be offering a new AA mode coming up soon for single ATi cards. No clue exactly what is/isn't supported yet as they haven't even really announced what it is yet, but rumor has it to be a MSTAA mode (alpha to coverage). And since tEd over at Beyond3D once again figured out how to hack the beta Catalyst 6.10 set to get it working I figure it's ok to mention it.

According to tEd you do it the same way you enabled TAA, but replace ASTT with EATM.
