I would have to replay to more specifically catalogue the places I noticed, but I do believe trying to use the key on the keyhole (clicking on it) seemed to freeze my cursor for a little bit.
I assume trying to load or instantiate something may have been an issue since it's pretty clear graphics aren't a problem.
interesting, that is not what I was anticipating. The only time during game play any objects are instantiated or destroyed are when an item is dropped/thrown with the right mouse button(instantiated) or a dropped item is picked up (destroyed) otherwise stuff is just moved around. The keyhole doesn't even actually destroy the key. it is just another container like the alcoves or sconces...
