you know what sucks? :)
going through 186 actors and unchecking the "moveable" checkbox on actors that never move! and unchecking "visible" on invisible actors! Talk about resource wasters 
I wish I knew then what I know now.
So, for all your newbies out there, if the actor doesn't move, uncheck the moveable checkbox under physics, and if it's not visible, instead of putting the alpha down to 0, uncheck the 'visible' option. Saves you a bunch of processing power, and someone (tshirtbooth?) did a comparison and found that it saves a bunch of FPS.

although doing anything to 186 actors is now fun
good idea!
