Well I really dont know what you're seeing but it looks fine. Its really just how the devs code the 3D image, some of its better some of its not. Your eyes tend to see less of the pop out and more of the depth after spending more time with the 3DS, for instance with the load screen ( where the squares pop out in the sides) that's one instance where the 3D seems less pronounced
As for Dual Screens, making it one screen wouldnt help with the resolution, lol.
