Load and run scene in background

Hey guys,

I want to load a new Scene(The main game) from the start scene(menu).

I use the following code:

AsyncOperation loadscene;

 loadscene = Application.LoadLevelAsync("Hauptmenü");
 loadscene.allowSceneActivation = false;

and then after I load some things I activate it from another script:

 loadscene.allowSceneActivation = true;

My Problem is that the Scene(main game) have to run a few seconds to load stats and other things... Is there a way to let the Scene(maingame) run, before I let the scene show?

Thanks for help!
