Hi Stuart, Sorry for the late response. The distance the instrument is from the "eye" is probably the reason for the difference. Zooming in is simply a matter of narrowing the fov making a smaller frustrum so that a particular component appears bigger on the screen. I'm talking about the actual distance the instrument is from the eye point. Z-fighting would be more likely as the instrument moves farther away.
