Adaptive Anti-aliasing
Adaptive anti-aliasing is a technique that applies a combination of multi-
sampling (MSAA) and super-sampling (SSAA) on 3D objects to improve
edge smoothness and fine detail. This feature renders 3D objects containing
transparencies more realistic, providing exceptional levels of image quality
while maintaining performance.

Adjust the Adaptive Anti-Aliasing control slider to the desired
setting.

Anisotropic Filtering

Anisotropic filtering is a technique that preserves detail on surfaces that
have three-dimensional perspective and fade away into the background. It
works best when used in conjunction with Mipmapping.
Anisotropic filtering can be set to favor either an increase in system
processing performance or improved image quality:
• Setting for performance is best used with applications that display
objects with smooth, simple surfaces, such as those seen in CAD
applications.
• Setting for quality is best used with applications that display highly
detailed scenes, backgrounds, and textured objects, such as those
seen in 3D games.
• If you are unsure how to configure anisotropic filtering, use the
