Good evening, first of all, please excuse my bad english, BUT: I had the same problem today and it occured when I changed some compatibility settings at the fsx.exe. So what I did to solve the frame rate issue, was that I just rechanged the compatibility settings as they were before. First of all you have to go into your Microsoft Flight Simulator X folder. Then you scroll down until you have the fsx.exe on your screen. Then you make a right click on it. Then click "properties", then "compatibility", then make sure you did not check the option to execute the program in compatibility mode. After doing this make also sure that you're not running the FSX as administrator. Now the frame rate should be better at all, and the Citation should be flyable. Best regards
