CSAA

Coverage Sampling Anti-Aliasing (CSAA)

Description

NVidia has an additional optimized form of MSAA, the Coverage Sampling Anti-Aliasing (CSAA). This method can achieve better results with fewer samples.

For example, an 8X CSAA has about the same memory cost of an 4X MSAA. But it uses more cover samples to achieve a quality similar to a true 8X MSAA.

How to enable

CSAA can be enabled using the nvPreset parameter.

Test program

There is an NVidia example in mwengine\tools\various\CSAATutorial to test the various presets.
