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. In this article since we are using higher performance (and more expensive) systems, we have used 4 x AA and 16 x AF at a resolution of 1600 x 1200 to try and stress the graphics cards more.
Once we turn on the AA and AF the SLI setup again flies ahead of the single 7800GT.
While our non AA and AF tests showed Half Life 2 performance similar when we do up the ante its clear that SLI offers a benefit.
We again see in our HQ tests that the SLI 7800GT setup offers exceptional performance.
