Theory Fast approximate anti-aliasing (FXAA). Is a post processing depth-aware edge filter. It’s a cheap and fast alternative to MSAA that can produce good visual results. The algorithm consists of two steps: Determine whether the shaded pixel is located on an edge. Smooth the problematic pixel values by applying a blur filter. Note that anti-aliasing methods such as FXAA should be applied prior to rendering the UI elements because the filtering process can have a noticeable impact on it as...
