When you turn the camera the perspective shifts, as if you're inside a cube with pictures on its walls. Is it that hard to fix to get more real feel like in a 3

When you turn the camera the perspective shifts, as if you're inside a cube with pictures on its walls. Is it that hard to fix to get more real feel like in a 3rd game? Edit: default zoom is too wide-angle. Zoom in and everything is so much better.
