instead of using _process on every object is it optimize to use your core code emit_signal to other object every frame ?
like this

#Core.gd
signal FramePassed
func _process(delta):
  emit_signal("FramePassed",delta)

Core.gd will emit signal every frame

#A.gd
func _on_Core_FramePassed(delta):
 #do stuff

A.gd receive signal then do stuff
