Loading in BGE

Hi Blenderartists,

I have a small question about loading of objects in BGE ( a landscape and trees for example ). Usually in most games made in BGE, objects are only load if you just see them (when they appear in game camera view). This is also the problem that the game lags for 1 second at several parts of the scene (but after that the game runs fluently).

Is there any possibility to let every game object in scene be loaded at the moment the scene starts ? Thank you in advance
