Default Re: ByeBye GTX280, Hello 8800GTX

Transparency SS = AAA. Its essentally supersample applied to alpha textures. It uses the value of its base multisample to determine the amount of supersampling applied too the alpha textures. 16xQ for instance applies 8x SS to all alpha textures. And 16x CSAA applies 4x SS to all alpha textures. This can be cheap or expensive based on how many alpha textures are being rendered. IN areas with heavy usage of alpha textures. Applying 8x supersampling to all alpha objects can be very fillrate intensive.

The Supersampling modes in Nvidia drivers are full screen filters. So 4xS applies a 1x2 SS filter to the entire screen. Or 16xS provides a 2x2 OGSS to entire screen. Sometimes just using a simple full screen SS along with transparency MS can be faster and provide a more consistent quality experience. You simply have to toy with the settings to achieve your desired results.
