RE Low quality assets. That is how you really push a system further in the generation, you figure out how to make lower quality things look better and better by focusing attention on key elements to mask it. ne of my room mates came by and I was playing the game, she asked if the PS4 version looks better and I said yeah, she said that was mind blowing to her.
The game uses what could be considered the worst environmental assets in the mainline series, relative to when it has all come out, but the attention to detail on the art side, particularly the lighting (and quality of the principle models and how closely focused the camera is) etc, really makes up for it when the image comes together. You do not even need to worry about the framey ness on current gen as much because of the type of game Metal Gear is, were as the kind of frame rate hitching in most other games would be considering a big issue.
