I'm using 1.52 with MemSaver turned on, and find everything runs much much faster... sometimes. Other times I'll load my game and find it much slower than it ever was, to the point of being unplayable. I'm not sure if there's exactly a pattern to this, but it seems like the first time I load a game after running Civ IV it's incredibly slow, but after any additional loads it's speedy. Anyone else having this issue?
