You will attempt to play down any example I give you because you wish to believe this trailer is running on base PS4 hardware/refuse to believe it might not.
It looks way better than the Witcher 3.
It looks comparable to the semi-open world sections in Uncharted 4, but on a much larger scale, in a dynamic open world, with random AI elements totally absent in those Uncharted segments. Additionally, it looks to have dynamic weather and lighting also absent in those Uncharted segments. And Naughty Dog = Naughty Gods.
If something looks comparable to U4 under much more taxing circumstances, I'm playing the Neo card.
