Could you post your Computer's DxDiag?
To gather a DxDiag on your computer, please follow the steps here: http://answers.ea.com/t5/The-Sims-3/HOW-TO-DxDiag-for-Sims-3-PC-Only/td-p/1049584/
You can attach the txt file to your post directly.
It's been a while since I was last on this post; I have some information I can attach to it.
Note that I have changed computers since; the issue still persists, however.
I have attached my DxDiag accordingly.
The new computer I have I had thought as well might have improved performance, however it appears that did nothing of the sort; with Parenthood out now and some of my families now expanding further, the game has become virtually unplayable now unless I start a lot with 1-2 Sims; a full house is impossible to play now.
I have uploaded my save files as well; I will have them PM'd to you directly.
