Q. How can I easily enable and change the quality of antialiasing?
As of the 6.xx+ drivers, you can enable and specify the FSAA quality directly from the NVIDIA control
panel.
There are a couple of free programs to enable you to both enable FSAA only when you run certain
programs (RunAA) and to easily set the FSAA settings from the task tray (GeForceAASet) available to
download at the following website:

Q. What do the different antialiasing options mean?
In the 10.xx+ drivers, there are just four antialiasing options:
Off (no antialiasing)
2x
Quincunx Antialiasing(tm) - GeForce3 only
4x
The further down the list, the higher the quality of the antialiasing but the greater the slowdown.
Quincunx will also cause the image to be slightly more blurry than the other two methods, but will
roughly give 4x quality with 2x performance.
In the pre 10.xx drivers, there were more options:
For OpenGL there are three options to pick from:
1.5 x 1.5
2 x 2 [LOD bias]
2 x 2
For Direct3D there are eight options to pick from:
1 x 2
2 x 2 (low detail)
2 x 2
2 x 2 (special)
3 x 3 (low detail)
3 x 3
4 x 4 (low detail)
4 x 4
The higher the two numbers, the better the quality of the antialiasing, the more memory required
and the greater the slowdown.
The [LOD bias] and (low detail) options mean that mipmaps are stored at the resolution that the
game is actually displayed at - otherwise mipmaps are stored at the resolution that the image is
processed at, which makes the image sharper, but also requires more memory and will cause a
slight slowdown.
The (special) option means that a special filtering algorithm is used that yields better image quality,
but is slightly slower.
