I tested to use FXAA approximate anti-aliasing by using the code from Timothy Lottes. It seems to work but I don’t get anything close to what I have seen in screenshots from others who have implemented the same code. The shots below shows FXAA with “preset 3″ as found in the original code. Looks like almost all “outer” edges don’t get any smoothing.

  1. Here are a few possibilities of what could be wrong: (1.) fragment shader input position could be off?, (2.) rcpFrame could be wrong? Be interesting to see what the debug options output (will be much easier to track down what is wrong).
