Also, the slowness doesn't seem to be confined to the sim's actions. Double clicking the sim's portrait to auto center on the sim is laggy as well. Instead of instantly moving to the sim upon double click, it takes about 2 seconds for the portrait to highlight, then 2 more seconds to start moving to the sim.
Update: Game restart solves the problem (so far), but ONLY TEMPORARILY!
