Lag when multiple MovieClip moving on screen?

[WitchXHunter]

is there anyway to solve it? I tried to create the maximum number of MCs I needed before hand and hide them out of stage when not needed instead of keep on adding and removing coz it lags that way too, the total number of MC is around 11. Thanks

if they are only moving (and not changing frames, alpha etc that would require a bitmap change), enable their cacheAsBitmap property.

Ohh I tried that earlier it still lags, and also I'll be needing the alpha too.
