I would like Sprite_fetch to be faster or to work asynchronously. I've already tested the application on several devices and on almost all of them the waiting time is the same until the assets are preloaded by sprite_fetch, which is a time of 1 minute and 5 seconds, varying a few seconds more or less .
This waiting time, taking into account the fact that the window is frozen while loading, can be a problem that can lead users to uninstall the application, since the game tends to be more popular on mobile. That wait time wouldn't be an issue if it was a PC-only game.
If I can't find a solution by tonight, publishing the app like this will be tough but I won't have any other option. I need a solution that works on Windows and Android and that helps to at least keep the user on the loading screen, as the screen is completely frozen while the prefetch is in use.
