AA Appearance
Mobility Radeon 9600
No Antialiasing - Serious Sam, zoomed section (300%)
Aliasing of the arch curve is clearly visible in the NoAA shot, the edge of the curve pixellated to a decent degree.
2X Antialiasing - Serious Sam, zoomed section (300%)
With 2X AA, the arch curve gets anti-aliased fairly well but the hardware leaves the bottom edge of the curve alone, keeping the same pixels as the original image.
4X Antialiasing - Serious Sam, zoomed section (300%)
4X AA goes a bit further, applying AA to the entire curve edge.
6X Antialiasing - Serious Sam, zoomed section (300%)
6X significantly softens the curve edge without losing detail, enhancing image quality.
GeForce FX Go5700
No Antialiasing - Serious Sam, zoomed section (300%)
Again, aliasing of the arch curve is clearly visible in the NoAA shot, the edge of the curve pixellated to a decent degree.
2X Antialiasing - Serious Sam, zoomed section (300%)
With 2X AA, the arch curve gets anti-aliased fairly well and the hardware doesn't leave the bottom edge of the curve alone, antialiasing the complete edge.
4X Antialiasing - Serious Sam, zoomed section (300%)
4X AA, due to the sample grid, is little better than 2X AA in terms of subjective IQ, giving a slightly softer appearance.
6XS Antialiasing - Serious Sam, zoomed section (300%)
You get a fractionally softer edge with 6XS with the texture antialiased too. Overall image quality is good.
8X Antialiasing - Serious Sam, zoomed section (300%)
The AA effect is much like 4X, with the texture super-sampling offering very good image quality but a 4X fillrate hit. It's the same AA mode that NV40 uses for 8X.
