At FG start up (with Windows 7) I have very low frame rates (1-3fps) for a minute or two. After that the rate increases to about 40.
Using Windows Task Manager I see that the CPU and memory usage are quite low during this slow period. However, switching to Windows Resource Monitor it is immediately apparent that there are significant network, disc and page file activity. Resource Manager points to MsMpEng.exe as the culprit. This is doing security scans on all the AI and Terrasync data that is read at start-up. If FG is stopped and then restarted, this slow down is not apparent, presumably because the AI and Terasync data is up to date. So in a nutshell, start up frame rates are low due to FG updating volatile data such as AI and Terrasync. The virus checker is making this even slower.

Something seems to be getting initialized either when breaking ground during takeoff or in a File --> Reset that is not getting initialized on initial startup.
