High Quality AA and AF
Our high quality tests let us separate the men from the boys and the ladies from the girls. If the cards weren't struggling before they will start to now.
We can see in our synthetic AA/AF test that the Ultra gives itself quite the lead when compared to the HD 2900 XT.
We continue to see a large gain on the Ultra when we have AA and AF switched on.
Nvidia's OpenGL optimization continues to give them the lead over any ATI cards.
