Another thing that bites me sometimes is environmental lighting. The camera tends to adjust its exposure time an frame rate depending on the light level. I must have spend an hour in the past trying to understand why my numbers had changed one morning. Finally it became clear that it was because I wore a dark navy shirt and the day before was a cream colored shirt.

In other words I was just holding stuff in my hand and was using a totally different background.

Other possible explanation for the latency difference are due to the IMAQ display. I discovered that the Image Info box doesn't draw directly to the screen, and you may find that it affects the latency to have it shown. Hide it with a right click on the display >> Visible. Any zooming of the image could add some.
