Well, we don't actually know what version they were taken on. It's likely they were taken at the highest possible rez, but possible that that was a WiiU build or a PS4 build or anything else. There's nothing insane about the graphical quality in these pictures, especially when you compare it to some of the 3D Mario stuff (3D World, Kart, etc) from WiiU. It's not as intense as the Uncharted 4 announcement was.
Maybe Playtonic can specify some... well, specifications for us.
Could we get what version, resolution, and if those were real time or pre-baked?
Make the forum great again.
