Have you tried setting the preview to Sreed, instead of OpenGL, and checked the camera movments?

Checking out that aspect may give a clue as to whether it's actually a fault of OpenGL or not.

I'm guessing your graphics card is newer than my FX5200, so I'd either say it's something to do with your current display drivers, or a bug somewhere else, because all cameras work at the same speed for me, unless I've got a huge number of things in the scene.
