i read it thinking it was not giong to be an easy fix and i'm right.
but what it sounds like to me is your out of ram for the program.
you got to remember the sim's and other games like them eat up ram to keep all the data running. now sim's been around for awhile and they should have got it using less ram but still the more you get in your game the more ram is used and the more cpu cycles so one of them is lacking. i'd say the ram could be added too by using the page file / swap file / virt memory. which ever your system is calling it.
just make that larger and see if that helps. of course making that larger takes up your hard drive space..
if you can make the L2 cache larger try that, it should help with the cpu.
but i gave up on the games like that because of those reasons. you just can't keep buying new systems every 3 to 5 months just to play that type of game.
