Camera Processing Script Causing Obscene Lag

(The subVI waits for the processing to complete before returning) Any wait in sequence with the code will slow down that loop, freeing up the processor. In my opinion, the vision loop as a lower priority than actually driving the robot. I didn't mention setting VI priorities last time to keep things simple. Setting the vision VI to a lower priority may help, but other processes may still be impacted. (Other low priority processes, that you may want to use reliably.) I would typically use both a wait primitive, AND priority settings to achieve the desired balance.

The get image vi appears to wait until the next image is available using a notifier.
