dithering psx

does dithering require more performance or on the contrary using dithering you gain performance?

 

[Shifty Geezer]

Dithering is a compromise to get an apparent better colour range from a limited palette. This saves RAM and if handled in hardware has no performance cost, but isn't as good as having the higher colour range.
