There is another interesting application for dithering that I've read about in the recent Uncharted 4 Brain Dump (Ctrl-F for "Dithering") here https://redd.it/4itbxq: Use dithering instead of alpha blending to fade out close objects. Alpha blending can be quite expensive while dithering just omits pixels. The result looks like this: http://allenchou.net/wp-content/uploads/2016/05/dithering-1-...
