Re: Sims 3 64 bit keeps crashing
@CatCrackerz The issue might in fact be the pets, although it's difficult to be sure. Plenty of players with hardware similar to yours have been unable to use the Pets EP without crashing, but that's not a universal experience.
Since you could originally play fine with pets, the animals themselves may not be the issue, but perhaps something else going on in the world, for example a pack of wild horses spawning somewhere inconvenient or a baby animal getting stuck. Inactive households will adopt pets too, and those can cause problems even if your own sims' pets are fine.
If you're willing to use mods, I can recommend some to try, although I can't promise they'll help without knowing the exact cause of the crashes. If you don't want to use them, try disabling all the pet-related options you can find within the game settings.
It's also a good idea to delete the five cache files in Documents > Electronic Arts > The Sims 3 every time you get a crash. (The files should be deleted regularly anyway.) For reference, they are:
- CASPartCache.package
- compositorCache.package
- scriptCache.package
- simCompositorCache.package
- socialCache.package
If there are any files in the CurrentGame folder, delete those as well. That folder should always be empty unless you actually have a save loaded.
