You may have a problem with SimCity 4 running slowly. We all have! Just view the forums about it. I have tried to run SimCity 4 on three top of the line systems with monster video cards and it still runs slow. SimCity 4 has to perform a lot of calculations and there are usually a lot of items on the screen, hence you might have problems with the game moving along quickly no matter what kind of hardware you’re running. Here are a few tips to help speed up the game a bit.
1. Check the graphics settings. Set everything to Medium or Low. It’s almost impossible to run the game without it being choppy if anything is set to High.
2. Try Software rendering instead of Hardware rendering.
3. If you want time to advance quicker, zoom into an area of your city that has nothing built. No cars, nothing. The game will run a bit faster because it doesn’t have to spend time rendering items on the screen.
