Those of you who have read the THG review of the 9800xt may have caught this, but if not...
Test tools don't help much anymore because they can be detected by the driver resulting in an optimal quality in those test apps. The only thing you can do today is to compare the quality in screenshots but those results are only meaningful for this single application. This way is also very time-consuming and you also have to capture exactly the same frame, which is only possible in a minority of games. It's getting even worse when it comes to FSAA because the image you see on your captured screenshot is not inevitably what you see on your monitor. NVIDIA is using a kind of post frame buffer filtering technology, which was already used by 3dfx's Voodoo5. It takes the samples from the frame buffer and finally combines them in the RAMDAC of the card. The problem is that screen captures can only be taken out of the frame buffer. The technology used by NVIDIA is valid but it complicates reliable screen capturing.

They didnt buy 3dfx for their hardware, they bought them so they could use the post frame buffer to sneak past benchmarks!
Heh.... j/k?
