If you've designed any Sims that you no longer play with or have any use for, delete them to reduce the amount of data needed for the save. You should also avoid using spaces or special characters in the save's file name.Īvoid long, continuous gameplay sessions, and instead save, quit and restart the game at regular intervals. You should also never use save and quit instead, save the game normally and then quit without saving - this process is less intensive and less likely to result in a corrupted save. Putting the city into edit or pause mode can also help ensure a successful save. Try to save during periods of low activity in your city, ideally at night while your Sims are asleep. You should also avoid playing 'The Sims 3' during resource-intensive tasks like anti-virus scanning or while running other resource-hungry programs like Adobe Photoshop. Closing out any programs you don't need can reduce this strain. When you run a lot of other tasks in the background, like media players and Web browsers, it can bog down your computer. Games like 'The Sims 3' are resource-intensive, especially on higher graphic settings. When you strain your computer with too many simultaneous tasks or processes, its performance suffers.
