Well wasn't really aware of this as this is my First ATI card, but I'm having horrid problems with the AA.
Now I've seen mixed results with ATI cards taking and not taking AA... Somehow I would imagine the 5800 series should beable to withstand anything you can throw at it rather then being taken down by a 4x AA... So... Whats up?
I'm running New Drivers just got the card today and 9.1 Catalyst
Spellborn 16xAF: 0xAA 27fps, 1x AA 24 Fps, 2xAA 17fps, 3x AA 14fps
Accuratly in Every game so far AA has had horrid effects on Fps more so then anything.. I mean I was getting nearly same Fps with my 8800GT on Spellborn, give or take some Fps on Aion. Mind you on Aion I was getting 35fps solid with Max everything.
That was the 8800GT! This should absolutely walk all over that.
If you have had an 8800GT before, you might have some Nvidia driver conflicts. Nvidia's uninstall doesn't completely uninstall the drivers in the registry. You'll need to download special programs such as DriveSweeper.
Make sure that, your old drivers were properly uninstalled, and the new one properly installed. Sometimes the ATI drivers have had issues completely uninstalling them selves, sometimes after market products will have to be used to get a good clean uninstall.
Supersampling is the most intensive form of antialiasing, where the whole frame is rendered at a resolution several times higher than the resolution you set in-game and then scaled back down again before being sent to the display device. It is extremely inefficient, so multisampling is normally used (which only antialiases the edges of polygons).
Triple buffering in the driver control panel only affects OpenGL applications for some reason, so changing it will generally do nothing.
