Your selection can range from turningantialiasing completely off to selecting the maximum amount possible for aparticular application. Use this slider to set the degree of antialiasing to be usedin Direct3D and OpenGL applications.Note: The availability of the following options depends on the type of graphicscard you are using.• Application setting allows the application to determine the antialiasing level.• Off disables antialiasing in 3D applications. Select this option if you requiremaximum performance in your applications.• 2x enables antialiasing using the 2x mode. This mode offers improved imagequality and high performance in 3D applications.• Quincunx enables a patented antialiasing technique available in the GeForceGPU family. Quincunx antialiasing offers the quality of the slower, 4xantialiasing mode, but at nearly the performance of the faster, 2x mode.• 4x enables antialiasing using the 4x mode. This mode offers higher imagequality 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 someperformance in 3D applications.• 6xS affects only Direct3D applications and enables antialiasing using the 6xSmode. This mode offers better image quality than the 4xS mode.• 8x enables antialiasing using the 8x mode. This mode offers better imagequality than the 6xS mode for Direct3D applications and better image qualitythat the 4x mode for OpenGL applications.• 16x enables antialiasing using the 16x mode. This mode offers better imagequality 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 ModesSome antialiasing settings require a large amount of video memory. If the modeyou requested requires more video memory than available and you seeunexpected results, try selecting the next lower mode, and so on, until youachieve the desired result.
