I also had to drop particle limits by 1/2 of what they were just to accomodate ATI chipsets.
That sucked, allot of eyecandy for temp GL polies were gone. After seeing what ATI did for the leaves in the 3dmark nature tests it clicked; they halved poly production in order to get speed.
That's what I saw at quakecon. That's what flipped me out when the weekend I spent on plasmabomb effects was effectively trashed on ATI's. It still looked better then WFA's, but not what I was posting screenshots on or what I saw with my measly GF2 400mx compared to the space-shuttle ATI's.
