I have a horrible problem with The Sims 3. The trees are seem to be like images. I have taken some photos:






I think it's a bug because when I approaching the camera, one or two trees appear.

Also, I have a problem with my own sims. Their hair doesn't appear. It seems to be like a wig.



Can you help me, please? I have updated my drivers. My graphics card is ATI Mobility Radeon HD 3450. Should I reinstall the game?

Thank you .
