One thing you could try is running JSBSim on the same machine in stand alone mode and connect it to FlightGear using the network interface (is this already possible)? There is an experiment that is sort of in-work, but not fully staffed. Jon smime.p7s Description: S/MIME cryptographic

I have been using the remote display interface for quite some time, using a proprietary aircraft model. Since the frame rates were basically the same as when I was using an internal model, I expected that the CPU usage was not impacted by that component. Does anyone know if it is the actual
