- Painkiller AF quality test

I used Painkiller to check not only the anisotropic capabilities of the 6800 Ultra, but also the Anti-Aliasing rendering quality. First let's see some pics I captured to again check the anisotropy.

On Painkiller, there is a nice spot where you can see the difference between the different Anisotropic settings. On the DM_Psycho map, there is a hall with bloody footsteps on the floor. I believe this spot is a perfect reference to test any VGA card's texture quality. Clean your glasses and observe carefully :)

AF OFF	2x AF

4x AF	8x AF

16x AF

The footsteps at the end of the hallway start to clear out at the 4x anisotropy level. Here again there is a slightly better quality at 8x and you can hardly see it on the marbles at the end of the hallway. I can't see any difference at all between the 8x and 16x level. Keep in mind though that games use Anisotropic Filtering in different ways. Also, some games do not even support 16x AF.

Enough with the Anisotropic Filtering. I hope the owners of the 6800 Ultra can make up their minds up on what anisotropy level to use. Now regarding the Anti-Aliasing quality all Nvidia's 6800 Ultras, use the following AA levels:

I grabbed some screenshots from Painkiller and Unreal Tournament 2004 to check the differences between the above AA levels.

To test Gainward's CoolFX 6800 Ultra Anti-Aliasing technique, I picked a scene which includes many edged textures. This scene can be found on the DM_Cursed multiplayer stage. On the following picture, you can see the area I used for the AA test. You can enlarge the image by clicking on it.

AF OFF

2x AF

2xQ

4x AF

8xS AF

As you can see, the scale effect has been totally smoothed out even at 4x. There is no visible difference between 4x and 8xS.
