Hello, my game was specially slow when my sim worked as architectural designer, when I tryed to build in neighbour's houses. Now it works fine, I did this:
- deleted (in the folder documents/electronic arts/sims3) the cache files (CASPartCache, compositorCache, simCompositorCache, scriptCache), and socialcache (I have just read this can make me lose active achievements )
- deleted every file in documents/electronic arts/sims 3/thumbnails (all the files in "thumbnails" folder),
and the same in the folder "worldcaches".
- deleted all the files in DCBackup and restarted the computer (I havent's any premium contents).
- I still repeat this steps from time to time.
After some minutes playing it was slow again, so I did this:
- renamed the folder "The sims 3" in Documents/electronic arts and renamed it The sims 3 Backup
- started the game (so the folder "The sims 3" was created again)
- then I closed the game and copied the save game I was playing from "the sims 3 backup/saves" to "the sims 3/saves" , a map that I created with worldtool (and reinstalled it with the launcher), the sims I created to the corresponding folder (savedsims), and the mods I was using.
Now my game works fine! I hope it helps someone, and I hope I explained it adequately in english because that's not my language.
