Giving my scene time to load before it begins?

hi... again and again 
Currently I have a play button that takes you to the next scene where the game starts straight away.
How can I give my scene time to load a bit before it starts because there is a lot of lag at the beginning and then calms dow mid way through.

will I have to put all the behaviours I already have inside my actors inside a new rule which holds ALL my behaviours?
For example RULE when attribute = true
Then all my behaviours inside this rule?
Have you ever done this yourself, how is it for the games performance?
thanks
Trouble is though with the 0.9.3 bugs I have to go into every single actor on the scene because of the editing prototype problems. oh well.. theres people in the world who haven't even eaten today and Im complaining about manual point and click labour.. Get on with it!!!
