You may want to write a simple test program to measure the lag so that we can quantify it compared to what others are seeing.

Click on My computer in the project, then press Ctl-N to create a new VI. In that VI, wire the Millisecond Tick Count to an indicator and add a delay of 1ms to the loop. On the same panel, read from the camera and display it in an image indicator. When you run the VI, you point the camera at the computer screen so that the camera captures and displays the ms counter.

Then, with this VI running, press the print screen key. The screen you captured will have the current ms count and in the image display next to it, it will show the screen as most recently captured by the camera. The difference between the ms tick count and the camera version will indicate the lag. You can take a few more screen captures to get a better statistical sample since the camera will not update but every 100ms based on your camera settings.

The attached image shows the core of the measurement VI.
