Something seems off about this resolution on the PS4, especially when we compare it to the xbone version's rez. 900p on the Ps4 with the bone version not too far behind at 800p seems to be very close with a similar framerate, usually the disparity is much larger looking at past multiplats.
Usually when the resolution is the same or close enough like it is in watchdogs, the Ps4 would be about double the framerate, a la tombraider. It would be interesting to know what the rez is on last gen consoles, it may very well be 640 x 480 looking at how much they butchered the rez on the next gen consoles, yet only managed 30 fps.
Something tells me we haven't heard the last about resolution talk about this game, something feels way off on this one.
