Antialiasing image quality - GPUs side by side
As on the last page, these images are from Half-Life 2, and they're just a quick-hit look at smoothing out (primarily) a couple of high-contrast, near-vertical edges. In these screenshots, the G80's gamma correct AA blending is turned on, while the G71's is turned off, for a very simple reason: those are the current control panel defaults for the two GPUs. ATI's gamma-correct blends are always on, I believe.

ATI 6X multisampled mode is still quite good, but the G80's 8X and 16X CSAA modes are now clearly superior.
