UPDATE:  This does not happen on the E175.  Only the E195 so far.     I have loaded this plane in various places with various scenery complexities, and just sitting at a gate or rolling down a taxiway without touching any flight controls, I get 30+ FPS regardless and I'm happy with that situation. But turning the plane on a taxiway, or doing a flight control check, or trying to maintain centerline on takeoff, the second I move the joystick in any way, the FPS immediately drops to 7 or
