I'm seeing that when I turn avionics on Cessna (GPS) it eats 20 FPS, goes from 44 fps to 23. This doesn't happen on MD80, it keeps fps at 40 fps most of the time.
So, is this a normal thing?... or sim need to be improved on this matter?
Edit: Using MD80's FMS if I leave it's display at INDEX screen I get 43 fps, but if I do change it's page fps goes to 19 .... is it normal?
