Long loading time on Android 11 #59

Describe the bug When you hit the "play" button in the bottom right of the launcher app, it takes about a minute and a half to start the game. At first I thought the app had frozen, but after waiting a long time the game does start.

Loading and saving also seem to take longer under Android 11 so I'm thinking this may have something to do with how storage is handled under Android 11.

This also happens with the stable version of OpenMW.

To Reproduce Steps to reproduce the behavior:

  1. Open the OpenMW launcher app
  2. Click on the play button.
  3. Wait... About a minute and a half for the game to launch

Expected behavior On an older phone running Android 10 (Pixel XL) the game loads almost instantly. No wait.

Same setup? Mods? Distant land?

Same setup as under Android 10, yup. I've tried disabling all mods and deleting my settings.cfg file: no change.

It's getting stuck in VFS::FileSystemArchive::listResources, the reason is new google's file access framework (that is automatically used for file access under /sdcard) is incredibly slow, as described in https://www.reddit.com/r/androiddev/comments/kpn68k/android_11_very_slow_file_access_performance/. Not sure there's anything I can do about it, one thing you can try is packing loose files into a .bsa.

Ok, thanks for looking into it, I kind of figured this might be beyond your control. I haven't had a chance to time it yet, but it did seem to speed up after the last Android update.

Thanks again!
