Like many other games, The Sims 3 is not working correctly with AMD/ATI Cards under GNU/Linux. First thing to try is to update graphic drivers to the latest version aviable.
You can follow the
AppDB entry for this game, if a solution/new wine version is working with AMD/ATI cards, it will be posted here.
Also note that many users report this game not working with wine without "disabling" copy protection, you can try that and see if it's better. Please remember PlayOnLinux is not supporting piracy so don't post link or demands for such files because, in Europe (and especially France), those files are illegals.
I'm sorry to not be able to help you more...
