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.
|Radeon X1950 XTX|
|GeForce 8800 GTX||Radeon HD 2900 XT||Radeon HD 2900 XT|
Narrow tent filter
|Radeon HD 2900 XT|
Wide tent filter
|6X||6X CFAA||6X CFAA|
|SuperAA 8X||8X CSAA||8X CFAA|
|Super AA 12X||12X CFAA|
|Super AA 14X||16X CSAA||16X CFAA|
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.
