Time won't speed up properly.

I have deleted my user files several times now, and it fixes the issue temporarily until it happens again at the cost of my progress. Ultra speed starts out fine and eventually becomes negligibly faster than normal speed, the game also becomes choppy on ultra speed when this happens. What can I do? I really don't feel like starting again only for the same to happen again.

My game did that when I was stressing the memory. (Really noticeable with a home ticket business on a 6x6 lot in a 3 story house with a disco room and game room with several pinball machines upstairs, 4 hot tubs and 6 poker tables downstairs, disco lights all over the house, and a lot of high poly deco... Along with my custom walls and floors that were a much larger file size than normal. (High poly walls and floors?) )

High speed makes it try to calculate everything much faster than otherwise. Walkbys, conversations, etc. still happen, but the game doesn't have as much time to compute it. If you are pushing the edge of what your system can handle, it eventually slows down the processing.
