Since we switched to Leopard, The Sims 2 gets sluggish after about an hour of play. I already checked activity monitor and stuff, but nothing is running in the background that could possibly make it slow down like that. Does anyone else have this problem? And what can I do to remedy this? I don't expect much help from Aspyr, as they only seem to fix the small problems and leave the bigger problems, such as characters getting stuck, untouched.
