Considering how old the hardware is,the graphic style,animations,atmosphere and the setting
it definitivly is.
The more powerfull Wuu I has graphicaly nothing that comes close to this game and even high end pc games will only look better because of higher resolution.
Wonder how a naughty dog game like uncharted 4 will look like with a 10-12time more powerful ps4?
Maybe it will look so great that there never be a need for a ps5 because the uc4 graphic standard would be so high that even a 10times more powerful ps5 could increase graphics only slightly.
