Antialiasing
Antialiasing is a technique used to minimize the “stairstep” effect sometimes
seen along the edges of 3D objects. Your selection can range from turning
antialiasing completely off to selecting the maximum amount possible for a
particular application. Use this slider to set the degree of antialiasing to be used
in Direct3D and OpenGL applications.
Note:
The availability of the following options depends on the type of graphics
card you are using.
• Application
setting allows the application to determine the antialiasing level.
•
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.
•
Quincunx
enables a patented antialiasing technique available in the GeForce
GPU family. Quincunx antialiasing offers the quality of the slower, 4x
antialiasing mode, but at nearly the performance of the faster, 2x mode.
•
4x
enables antialiasing using the 4x mode. This mode offers higher image
quality at the expense of some performance in 3D applications.
•
4x, 9-tap Gaussian
enables antialiasing using the 4x, 9-tap (Gaussian) mode.
This mode offers higher image quality but at the expense of some
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.
Note:
Some options may not be available due to your hardware limitation.
Please consult your NVIDIA User Guide for details.
Tips on Setting Antialiasing Modes
Some antialiasing settings require a large amount of video memory. If the mode
you requested requires more video memory than available and you see
unexpected results, try selecting the next lower mode, and so on, until you
achieve the desired result.
