It does sounds like a fill rate issue. The draw traversal must be growing because the GPU is not coping with the amount of overdraw that is present when you zoom and look at a shallow angle - so it the draw thread ends up blocking on a a full OpenGL FiFO. A good check for fill limit is to reduce the window size, if the frame rate goes up then you're almost certainly fill limited.
