Heads up Hawker drivers

I've been whining about low frame rates and pronounced stuttering with the Hawker. Carenado have been trying to duplicate the problem without success. Today I believe I have isolated the problem. It appears that there may be a conflict between the Hawker and in my case the Carenado  S550 Cessna. I uninstalled the Cessna and my frames returned to normal with no more dips to less than 5. Carenado are investigating. Could be other conflicts for those who have reported such low frames.
