I honestly don't think there's much of an excuse for the graphics regardless of FPS. especially when we consider that a lot of this game appears to be a rehash of the Nintendo 64 iteration in terms of art design
it's not like they appear to have rushed out this Star Fox game, I don't understand why it looks so mediocre. I actually think it looks appealing to the eye, it's just that it certainly isn't top of the line for the Wii U and you sort of expect a Star Fox game to have fairly advanced graphics for its generation when looking back at some of the titles in the series (Star Fox Adventures, love it or hate it, had great graphics for that generation and the same can be said for SF 64 on the N64)
in the end I guess gameplay is king but I'd like to see things pushed a bit more. it gets concerning when we think back to the Metroid Federation Force trailer and its god awful graphics (although early in development), because it makes you wonder if Nintendo is aware that a bulk of their fans to care about graphics at least a LITTLE bit, at least fans expect it to look good in comparison to other Wii U games which it doesn't really
