SMAA
A post-process anti-aliasing that reads an image's edge patterns morphologically and softens them, with better quality than FXAA at low cost.
Subpixel Morphological Anti-Aliasing was presented by Jorge Jimenez and others in 2011–2012, building on MLAA (Reshetov, 2009). Rather than supersampling — as MSAA does — it hunts for staircase edges in the finished image, classifies their shape, and blends pixels along them. The result is sharper than FXAA and plays well with deferred rendering, where MSAA is expensive.
SMAA comes in several modes, from pure post-process to variants that fold in temporal information between frames to damp flicker. It became a common option in graphics menus through the 2010s.
