iOS iOS large memory usage

Pedro Jones

Member
My game is very optimized and it doesn’t have any memory leaks on Android, but on IOS (with Xcode 11) it constantly receive memory warnings and after a while it closed.
I checked the memory usage of my game with the debug tools and I got the next results: 39 MB of memory usage for Android and 160 MB for iOS.

I read the reason is that since iOS 12 or Xcode 10 Apple is forcing to developers to use a new memory feature called: Metal Memory (https://forum.unity.com/threads/ios-large-memory-usage-apparently-feature-not-a-bug.637660/) (the issue is not Unity specific but rather a memory policy on the iOS platform)

And apparently the new memory feature multiplicate the memory usage of the games, but there are some recommendations to reduce memory for this new feature: https://developer.apple.com/documentation/metal/reducing_the_memory_footprint_of_metal_apps

but I don’t have any idea how to implement those recommendations in the Xcode project generated by VM/YYC runner.

Anyone has the same issue?
How did you deal with this issue?
Do you think that Game Maker 2 needs an update to fix this issue?

YYG suspect that it might just be memory which was being allocated on the apps behalf by the OpenGL driver is now being shown as owned by the app (but was always there), but they are currently investigating the issue to be sure. If your app is crashing and you suspect it is because of this in some way, then please file a bug report and include a link to a YYZ of the app as well as instructions on how to cause the crash.

Theres no crashes on newer iOS devices just a poor game performance due to the large memory usage, but on older iOS devices the game is closed after a while because the memory usage limit is smaller than newer iOS devices. It works perfectly on Android.

I would like to include a link to a YYZ of the app, but I'm just an employee of Pengu games and I don’t have the permission to file the yyz. But I can file the Xcode report (It mentions OpenGL)
