With this patch, only sensors that are connected to active states are actually registered in the logic manager. Inactive sensors won't take any CPU, especially the Radar and Near sensors that use a physical object for the detection: these objects are removed from the physics engine. To take advantage of this optimization patch, you need to define very light idle state when the objects are inactive: make them transparent, suspend the physics, keep few sensors active (e,g a message sensor to wake up), etc.
