Played on the GamePad, Fifa 13 on Wii U looked twice as good as on a TV. It will be even more true on Switch's screen. The smaller screen size hides aliasing & makes everything more detailed. If the port is decent, I'm sure it will turn heads played on the go.
That view is in every 2k game.... used to be the default view.... they moved away from it as default a few years ago.
I have no idea how you can tell anything about the graphics in that small pic. its most likely mocked up anyways (ps4 ver on that screen in the add)
