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. ATI are able to offer HDR and AA at the same time unlike nVidia so we have ran our HQ Lost Coast test with HDR on.
Our AA tests show very similar results with the X1900GT being the clear winner of the stock cards. It's not until we overclock the XFX 7900GS that we see it sneak ahead of it.
Turning on AA and AF we see similar results with again the X1900GT and 7900GS sitting very close to each other, the 7900GT clearly pulls away from the others but the 7900GS overclocked continues to pull ahead even further.
Finally we leave with PREY and some OpenGL love for nVidia. As expected the results are hugely in favor of the nVidia line up and the overclocked 7900GS just gives us surprise after surprise.
