Since my customized FXAA code was successfully covering up the fact that SMAA was nonfunctional in HQAA for a
very long time, I've decided to release it as a "lightweight" high-quality option. It is slower than traditional FXAA, but not by terribly much - and my testing generally seems to indicate that it produces
significantly higher image quality than even the highest possible preset in FXAA.fx (my opinion, but I'm also frankly giving it quite a bit more leeway to be accurate instead of fast). Give it a try if you're looking for something visually along the lines of FXAA, but with less blurring and artifacts.
