    The following parameters are available for selection when viewing/changing antialiasing settings.


    I have no idea what either 2xQ or 8xS are? I'd be grateful for some help :)

    The S and Q are optimised nVidia settings. They basically give slightly less visual quality than the number they represent but give significant performance over the number on it's own. The visual difference is supposed to be very, very small and completely outweighed by the performance at that visual quality.

    EDIT : Actually, IIRC, S is for performance optimised like I said above, but Q is for visual quality enhancements but less performance....yes, I think that's right now.

    2xQ is Quincunx (sp?) AA. Gives almost the qulaity of 4X AA with the speed of 2X.

    ATleast that was the published spiel back in the day.

    8xS is quality mode- this is the best AA mode of any single gfx card as it combines 4X MSAA with 2X SSAA (super scene) meaning the textures/alpha textures and shaders will also be AA, unlike with MSAA. However, there is a big performance hit when using SSAA.

    Yeah, I knew it was something along those lines back from my FX days :D.
