I'm loading a rather large data file during Init()
The result of this is a black screen being displayed for about 8 secs whilst the file loads.
How can I display some kind of indication that a file is loading ?
I am not loading any World related stuff.

The best way is to put the load process on a secondary thread, while the main thread is doing the drawing (and rendering) of the loading indicator (ie. spinning icon, etc).

Excellent! That works very nicely.
