I would say it is a poorly designed game, the game using cartoon artwork (that looks good enough mind you) get only 900p, while Detroit (from a much smaller studio than S-E) looks much much much better and more taxing. |
The two are very different games to be fair; Detroit is almost an interactive film where the highest priority is placed on realistic graphical fidelity; DQ11 is an open world game where graphics are less of a priority and the visuals aim to create a clean, CG-like cartoon look.
As Nuvendil already covered, UE4 is just a demanding engine in general in terms of its feature set, and games made with it tend to run at lower resolutions than you'd typically see on the same hardware.
