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.
As soon as we really crank on the pressure the Radeon X1950GT really can't handle it as we again see the GT lagging behind a lot like in our non AA and AF 3DMark06 tests. The GT saw advantages at high resolutions but in these tests it appears as if AA and AF prefer faster clock speeds rather than extra memory.
The extra memory really doesn't help the GT as with this much load on the graphics card we are coming down to raw power which is a result of clock speeds.
Finally we see the GS win thanks to its OpenGL optimization, the PRO sits just behind it and the GT really falls to the back of the pack in our final test.
