Those shaders are packed with a 3rd party SMAA injector, created by mrhaandi, which is still available and still distributed with SweetFX original package. SweetFX packs some post-processing shaders like LumaSharpen, Technicolor, Sepia and Vignette to name a few, giving the ability to change games colors and other effects beyond original game settings. SweetFX is the name of a shader bundle created by ceejay.dk with collaboration from other community users from Guru3D and other internet forums.
