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.
Like our non AA and AF tests the CrossFire solution again beats the 7800GTX SLI. We can also see the quite major increase between the single card solution and CrossFire where the non AA and AF shows the performance to be less.
Half Life 2 shows both SLI and CrossFire very close to each other, there is roughly a 20% increase over the single card solution.
Again we find that the ATI CrossFire solution wins at Doom 3 and almost a 40% increase in performance when moving over to CrossFire when compared to the single X1900XTX.
