High Quality AA and AF
In our High Quality tests we bump the Antialiasing (AA) and Anisotropic Filtering (AF) up causing the card(s) to be put under more load.
This usually helps us remove the CPU limitation. We are using 8 x AA and 16 x AF. Since we are using such high-end cards our AA and AF tests while not only being bumped up in quality are moving to 1600 x 1200 to remove the processor limitation as much as possible.
Our AA and AF tests show us a similar picture with SLI 7600GT beating a single 7900GT and SLI 7900GT performing very close to a single 7900GTX. SLI 7900GTX clearly stands out though with a huge score.
3DMark06 paints the same picture as our benchmark above except the fact that the scores are lower due to it being 3DMark06.
While our non AA and AF tests did not like SLI all that much, you can clearly see when we start running a high resolution and bump the AA and AF right up, SLI begins to show its benefits.
Doom 3 again like Half Life 2 sees some serious performance increases for SLI when we bump up the AA / AF and resolution.
