We would also like to explain why the graphic quality options are available on Android and are not shown on iOS.
As many of you have unfortunately noticed, since the release of the iOS Version, we experience crashes of Aerofly FS Global on selected devices. Unfortunately this is due to low memory on those devices, even though the CPU itself is very fast. It's like a Porsche engine with some really bad tires.
On Android we do have a lot more hardware variations but at the same time almost all devices we support have enough RAM compared to iOS. So we give the user the option to choose the quality setting as it usually won't result in a program crash even if the device is too slow. On iOS on the other hand, the quality options would almost certainly result in a crash on non suitable devices with low RAM. So that's why we have hard coded the quality setting in the iOS version.
We intend to optimize the memory usage in successive updates, but as a rough summary, we cannot display the same amount on detail on many iOS devices due to limited RAM.
