Using FXAA

The "FXAA" effect applies Fast approXimate Anti-Aliasing to the layer. This is a high-speed anti-aliasing technique that removes some of the "jaggies" from the image without impacting performance as heavily as super-sampling would.

  • Pros: easy fix for many aliasing problems; works with moving images (unlike Progressive Anti-Aliasing).
  • Cons: can blur and otherwise 'munge' fine text details present in the layer; as a screen-space heuristic technique it can sometimes leave sharp edges that ideally would be anti-aliased.
