[Graphics]Anti-Aliasing Notes - FXAA, MSAA and TXAA

Keywords: Graphics, Rendering, Anti-Aliasing, FXAA, MSAA, TXAA, SMAA

Overview

TXAA looks like shit.
FXAA when implemented well looks good.
MSAA is a good one but you need 8xMSAA depending on the game.
SSAA is superior to everything.
DSR makes things blurry.

DSR (Dynamic Super Resolution)

One of the more intriguing capabilities Nvidia introduced with the GeForce GTX 970 and 980 is a feature called Dynamic Super Resolution, or DSR, for short. DSR is a way for a fast GPU to offer improved image quality on a lower-resolution display. Nvidia bills it as a means of getting 4K quality on a 2K display.
