FXAA Shader

Beskrivning

Fast approximate anti-aliasing (FXAA)

For this to work correctly, you must disable the default anti-aliasing in the settings.

Reduces visible aliasing while maintaining sharpness and keeping within a
practical ms/frame cost for a typical game engine. Cost to process a 1920x1200
frame on GTX480 is under 1ms for FXAA preset 2.
Targets aliasing both on triangle edges and in shader results. FXAA has logic to
reduce single-pixel and sub-pixel aliasing: see the reduction in stipple aliasing in
the jittered sampling shadow area.
Is easy to integrate into a single pixel shader. FXAA runs as a single-pass filter
on a single-sample color image. FXAA can provide a memory advantage over
MSAA, especially on stereo and multi-display render targets or back buffers.
Can provide a performance advantage for deferred rendering over using MSAA
and shading multiple samples.
