I ran into the problem, that I wanted to get rid of the FPS display in lower right corner of the screen.
As there is not any dialog with a checkbox for this setting I tried the user manual. Nice to read that Shift+I toggles the display ... :confused:
Only problem: Shift+I toggles Flight info and NOT FPS display
If somebody runs into the same issue here is the hack to get rid of the FPS display:
Find the file: C:\Users\<username>\Documents\aerofly RC 7\config\main.mcf
Open it in a text editor, and change the line
No guarantee for wrong editing, so be careful if you do this !!!
