I tried. The amount of aliasing on Link's sword on Melee isn't different for me. Well, to be honest, pixel positions seems to be a little different, and maybe edges looks very slightly better, but it's almost unnoticeable, even FXAA or 2xMSAA do a better work. Better texture sharpness is true tho. I used DX11.
From France with love.
