White world

Hello, I recently installed the Sims 3 on my toshiba satellite c50-a-17q (windows 8).

But when I want to start with a new world, the only thing I see is that this world is filled with white.

Except for the sea (which is plain blue) I can't see anything (no houses, no surroundings and suchlike).

Right after installing the game warned me that it can't read my videocard.

I already adjusted the quality, but it doesn't seem to work.

How can I fix this problem?
