What is your RAM?
Is every graphic setting to low? View > Rendering
ALS off
3d clouds off
All shaders to minimum
Rembrandt off

What is your CPU
What is your graphics card anyway is it an intel hd graphics 4000 or what?
Anyway if all settings are to low or off you need a new computer. Sorry.

it sounds as if you're running FlightGear without hardware acceleration - if in doubt, run a few OpenGL benchmarks to see for yourself whether the problem is specific to FlightGear or not.
On Windows, "FurMark3D" would be a common test suite to test your computer's capabilities
