By design Aerofly FS is kept user friendly and having to find the optimum graphics setting until it runs smoothly is not the right way to approach this.
We already optimized the graphics quality and performance for you so that you don't need to worry about these kind of things and so that you can set something that your device can't handle. This way we can even adjust the graphics quality throughout the flight to keep Aerofly FS running smoothly. Allowing all users to turn everything on every setting would drastically decrease the frame rate or even cause crashes on lower end devices. We don't have these manual settings so that users are not able to crash the app or even overload their smartphone or tablet to a point where the entire device crashes
Agreed - great call Dev Team. This is what keeps this sim’s usability and functionality great is all the optimization is done behind scenes so sim user can focus on the objective flying.. not counting frames and worrying about aliasing.
