The Spain guys uncovered a problem with X-Plane 10 that calls the animation loop about 3 times more often than (I) originally anticipated. The design was to send one packet per frame rendered; most people’s systems run around 30fps (I’m lucky to get 20 on my MacBook Air). I’ve added a delay timer so that no more than 30 updates are sent per second, which translates roughly to 40-50kbps of data transmitted. I haven’t had a chance to test it on Windows yet. It loads just fine on OS X and seems to have cut down on the amount of data transmitted.
