How do you set the frame rate? Free run (default) or TRIG, TRIG_CONDITION
and TRIG_PERIOD parameters?

How do you check frame rate? In the camera control interface?
Sometimes it can be incorrect. If the number is green then exposure is
short enough for the maximum fps. If red - then exposure limits the frame
rate.
What's the exposure time? Set it to 10 ms, for example.

The better way to check the fps:
