Configuring Key ForceWare Graphics Driver Features
• Application‐controlled. To configure options with the slider, you must clear this
check box and click Apply. If you select this check box, the configurable options
are automatically disabled because your application determines the antialiasing
settings. To configure options with the slider, you must clear this check box and
click Apply.
• Off disables antialiasing in 3D applications. Select this option if you require
maximum performance in your applications.
• 2x enables antialiasing using the 2x mode. This mode offers improved image
quality and high performance in 3D applications.
• 4x enables antialiasing using the 4x mode. This mode offers better image quality
but can slightly reduce performance in 3D applications.
• 6xS affects only Direct3D applications and enables antialiasing using the 6xS
mode. This mode offers better image quality than the 4xS mode.
• 8x enables antialiasing using the 8x mode. This mode offers better image quality
than the 6xS mode for Direct3D applications and better image quality that the 4x
mode for OpenGL applications.
• 16x enables antialiasing using the 16x mode. This mode offers better image quality
than the 8x mode.

Anisotropic Filtering

Anisotropic filtering is a technique used to improve the quality of textures applied
to the surfaces of 3D objects when drawn at a sharp angle. Use the Anisotropic
filtering slider to set the degree of anisotropic filtering for improved image quality.
Enabling this option improves image quality at the expense of some performance.
• Application‐controlled. If you select this check box, the configurable options are
automatically disabled because your application determines the anisotropic
filtering settings. To configure options with the slider, you must clear this check
box and click Apply.
• Off disables anisotropic filtering.
• 1x results in maximum application performance.
• 2x through 8x results in improved image quality but at some expense to
application performance. Higher values yield better image quality while reducing
performance.
