bad lag in vi using "initialize array"

Thanks for posting the solution. That's always helpful to others if they run into the same problem. It also lets NI support that the problem has been solved and they don't need to get involved.

Hi Candice,

So far these have all been great suggestions.  If possible could you try this?  On the IMAQ ArrayToImage.vi wire the image into the Image Pixels (I16) instead of the Image Pixels (Float).  Then change the IMAQ Create to Grayscale (I16) as the input.  This should cause your VI to run at regular speeds.  I was able reproduce your situation and changing the inputs changed how the VI behaved.

I'm going to look into something on my end but I believe it may be related due to the IMAQ Expand.  I will post back with my findings.

Yes you got it. That's almost exactly what the problem was. Thank you so much for your time!
