I load MSFS & Select flight from London City Airport, (EGLC). I am Flying the Bell-47G. I fly around & FPS is roughly around 30 FPS. I then land too hard & sim tells me I damaged gear & gives me the option to restart Flight or go back to menu. If I restart Flight then the Flight loads again but instead of 30 FPS I get 19-24. To me this is weird as nothing has changed! Anyone have any idea why? Suggestions/work arounds?
