My game has become more jerky since the patch. The further into it I get, the jerkier it gets. I'm not sure if it has to do with the number of game saves I have (every step I make a new save, so about 45), or custom furniture patterns. I suspect though, that it may have to do with the number of sims that get generated as the game progresses. Every time you have a responsibility that requires delivering to someone, or converting 2 new peterans/jacobans the game generates more npcs. The longer I play without quitting it gets jerkier too. It's a little smoother if I restart the game, but not by much. Having 3x speed is not necessary at the moment, because it never goes that fast anyway. The game freezes in CAS if I try to use a saved custom pattern, and I have the same problem of saved sims being VERY slow to load. It's also slow coming out of buy mode.
