Threshold for applying FXAA to a pixel, relative to the maximum luminosity of its 4 immediate neighbors.
The luminosity of the current pixel and it's NSWE neighbors is computed. The maximum luminosity and luminosity range (contrast) of all 5 pixels is found. If the contrast is less than RelativeContrastThreshold * maxLum, the pixel is not considered aliased and will not be affected by FXAA.
Suggested settings:

Subpixel aliasing is corrected by applying a lowpass filter to the current pixel.
This is implemented by blending an average of the 3x3 neighborhood around the pixel into the final result. The amount of blending is determined by comparing the detected amount of subpixel aliasing to the total contrasting of the CNSWE pixels:
SubpixelBlending = abs(lumC - lumAveNSWE) / (lumMaxCNSWE - lumMinCNSWE)
This parameter sets an upper limit to the amount of subpixel blending to prevent the image from simply getting blurred.

Use an improved edge endpoint detection algorithm.
If true, a modified edge endpoint detection algorithm is used that requires more texture lookups, but will properly detect aliased single-pixel lines.
If false, the edge endpoint algorithm proposed by NVIDIA will by used. This algorithm is faster (fewer lookups), but will fail to detect endpoints of single pixel edge steps.
Default setting is true.

Set the number of iterations for the endpoint search algorithm.
Increasing this value will increase runtime, but also properly detect longer edges. The current implementation steps one pixel in both the positive and negative directions per iteration. The default value is 12, which will resolve endpoints of edges < 25 pixels long (2 * 12 + 1).
