FXAA does AA on full screen post-processing and may introduce blurriness
SMAA based on MLAA post-processing and may add temporal AA to the mix (which causes shadows for slow moving objects) *
TSSAA/TXAA uses temporal information (previous frames) to do AA, but the averaging may cause blurring/ghosting
MSAA is the traditional approach but takes more resources, only super sample on polygon edges
SSAA super sample AA, super sample on all pixels
DLAA Deep learning Super Sampling (nVidia) AA
DSR Dynamic Super Resolution
