in internal trigger framerate is always enabled
when setting trigger mode to IntTrig the camera setTrigger() method enable the FrameRate, if a previous frame rate, aka a latency time greater than 1us, has been set you will get an acquisition not running at maximum frame rate you expect. The issue is Lima CtAcquisition will first set the exposure then the trigger mode, so basler plugin must not reenable FrameRate if latency_time is ~0. .
