I've actually found it quite difficult to use my peripheral vision, but that's because at a certain age I started making it a habit to look at every thing in a room individually, mapping out the items and locations mentally. Since then I've just sort of done it sub-consciously... I can't tell you how many times I've been in one of my friends god awfully dirty rooms, they lose something, and I find it having some how mapped out its location.
But, yeah, it gives me a lot of trouble playing video games. Probably why I don't like them that much.
