Antialiasing image quality - GPUs side by side
Here's a look at the Radeon HD 2900 XT's edge AA image quality. These images come from Half-Life 2, and they're blown up to 4X their normal size so you can see the pixel colors along the three angled edges shown prominently in this example.

CFAA's tent filters look reasonably good in these classic edge cases, as do AMD's 8X multisampled and SuperAA 16X modes. I think our example from Oblivion on the previous page does a better job of showcasing the tent filters' strengths, though.
