:( Would some body please tell me that in the scenery library, there are two radio buttons for each file. Do I need to select the "Cache this Scenery" button for every world file (from 01 to 91) in TP photoreal world files and UNCHECKED the optional box"Empty this scenery cache on exit" for better performance or to use the sceneries later when you fly the same situation again ?Many Thanks

I never changed these settings from the default. In fact, you might want to consult the simulator's online help (F1 key?) about these options.
