    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.

    We have just send in another update for Aerofly FS for Apple iOS that will reduce the memory consumption while using the global scenery streaming service and that will also reduce memory consumption on selected devices. We hope this fixes the crashes on some devices with less RAM memory.

    Please keep in mind that we cannot display the same amount of graphics details on all devices. Especially on 'slower' iOS devices we can't display any cultivation buildings as these devices do not offer enough RAM memory.

    As mentioned previously, by default Vulkan uses a different depth buffer method that improve precision for far away objects. In theory this is available with OpenGL as well but it requires the driver developer to expose a certain extension which isn't available all the time.

    Vulkan would be the best option but again it isn't supported well on the majority of devices out there.

    Dear Aerofly FS Global users,

    now that our new Aerofly FS Global is out for Apple iOS and Android we would like to comment on some of the new features in it compared to previous versions of Aerofly FS.

    Aerofly FS Global can now display cultivation data world wide for example houses, lights and other data like power plants or wind turbines. This data is available in a small region in our base scenery around San Francisco and is available world wide if you opt into our global scenery service. The amount of data is quite large and increases the amount of memory considerably compared to previous versions. Right now we have close to 1 TB of data available with aerial image quality of up to 2 meters per pixel in selected regions like USA and Europe. We now offer a total of over 7000 airports world wide. Many airports feature unique buildings and terminals but we will add many more highly detailed airports in the future. For example Australia just received a major update with Syndney ( YSSY ) featuring unique terminals and the city itself offers unique buildings as well. Again, this is an ongoing process so expect to see better airports in the upcoming months.

    If flying in a high/ultra quality setting over densely populated areas Aerofly FS might now use around 3.5 GB of RAM in total.

    On Android the users have the choice to set the graphics quality by themselves on Apple iOS this is currently set automatically depending on the device in use. On Android the devices usually have more memory available compared to iOS so it's safe to offer those quality options. Aerofly FS might not run well if the users chooses a too high quality settings, but it usually doesn't result in program crashes due to out of memory conditions. On Apple iOS we usually have a lot less memory available and if we offer these options the user will quickly get app crashes over densely populated areas, that's why we don't offer this settings for now. In general we recommend the user chooses a settings so that the FPS ( frames per second ) are at least 20 FPS or more.

    Cultivation buildings are available on Android once you choose a high ur ultra graphics quality setting. Below that only night lighting is available. On iOS so far only very powerful devices like the IPhone 14 Pro and 15 Pro and the new iPad devices set the high or ultra quality settings internally.

    Besides that Aerofly FS Global now features basically the same aircraft visual quality that our PC version offers, meaning that the texture resolution as well as the shader features are the same. You should immediately see that inside the cockpit where you now have shadows and the overall clarity of the cockpit texture resolution is also much higher.

    We will update this posting from time to time with more information.

    Implementing an offline mode is something we might consider in a future update. For now to keep the data consistant, we have deactivated the use of the already cached files. Content is continously updated, especially airports are getting updates on a daily basis, so we wan't to ensure this content is actually delivered to the user.

    @andiflyit: Loading times for Aerofly FS 4 and pretty much the same as for Aerofly FS 2. Streaming of scenery data is completely optional and does not affect the performance. The offline content for Aerofly FS 4 includes all the required high resolution aerial images, airports in Europe and USA and is not of lower quality compared to streaming. The streaming content just adds many more airports world wide which is a work in progress status, meaning, they will be improved over time.

    Overloaded: Do I hear a sarcastic undertone? If you are so unhappy with our products and do not see the improvements we did in the past, you might want to look at an alternative? I also have to add that buying our simulator is completely optional, so if there are no improvements for you, wait for the next version ( or the next one after that ).
