I'm attempting to sync two simulator's positions up using SimConnect. Currently, I have it set up to manually step the position every 10ms on the client side. The server side sends data every 100ms to the client, and the client calculates the velocity required based on that. However, there seems to be a sort of stuttering that occurs every time data is received from the server. Does anyone know how to create an algorithm that can smoothly sync position? (Maybe using extrapolation or something). Also, occasionally, SimConnect will through a COMException in various places (It's random) with the code 0xC00000B0, and I have no idea what that means. It's unfortunately not documented anywhere... Any help is greatly appreciated.
