1. Say there were like hundreds of activation regions in a single scene. Would that have a negative impact on performance?

2. Is it possible to create a floating activation region? Like an activation region attached to the view so that anything that comes into view is loaded and anything that leaves the view is unloaded.

to dp number 2, just put a single region and place it anywhere, but now i dont tink it would work. but it worked whit sooner version before 1.3.4

You can have many Activation Regions as you want, but you can't move the this regions in game mode.
