I agree I get low FPS Occasionally, however, I am running a script that counteracts the 'time compression' effects of X-plane so that I can achieve normal speed.
Additionally, I'd like to know if it's possible to add this feature: When you turn the volume knob in your simulator for the radios the volume level is reflected in the Pilot Client. It came to mind when I noticed that if the client can tell if the aircraft has power to the avionics then this volume feature might be possible. I am eager to hear your thoughts on this!
