OK, FINALLY got a chance to check out the packet situation with the jet. As mentioned earlier, the packet count was through the roof!
The average packet count for the jet was about 816 per 30 seconds, or about 27 packets a second! As a frame of reference, the Acceleration Hornet usually puts out about 120 packets every 30 seconds, or about 4 packets a second.
So I did some investigating. With the jet just sitting on the runway, engines running, I disabled all of the effects. The packet count went from 816 down to 149! After going through each effect one by one, it turns out the Smoke and Heat Shimmer Gauges are the culprits. The Smoke gauge causes a 532 packet increase, while the Heat Shimmer is responsible for a 135 packet increase (per 30 seconds). All together this creates a 667 packet increase. Add it to the average 149, you get....wait for it....816!
So out of the 20 effects gauges that the jet has, the smoke and heat shimmer gauges are causing all of the trouble. I will work of them this week to see if I can fix.
