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.
When we move to our HQ tests we see again that the 7900GS lags behind.
Turning on the AA in Lost Coast we see that the 7950GT overclocked offers a playable setup while the others would be slightly arguable. Some would say you want to see an average of 50 others would say 30.
The 7900GT and 7950GS clearly fly ahead of the 7900GS when we turn on AA and AF in PREY.
