It stopped when I went into the options while in the game and clicked on restore default settings. It stopped the semi invisible fur on the dogs. That's all I checked, but then obviously the rest of the quality of the graphics suffer so you have low detail Sims and lots etc, which isn't what I really want. Then, when I try and put all the settings on high it just goes completely schitzo and just has a white screen with all the little purple house and lot buttons etc, so I really don't know what to do :/
