SL running EXTREMELY slow...

I just downloaded this game, it's running just fine on my brothers computer, but when I try to play on mine it runs EXTREMEMLY slow it take two minutes or more for anything I click on try to do to pop up, and trying to walk is impossible. I havn't been able to do ANYTHING yet. And every time I close it down it gives me the "program not responding" error. I know my computer isn't as fast as my brothers, but it's fast. And I just bought a new vidoe card recently. As far as I can tell my system meets all requirements.
Could it possible be because my brothers playing it on his computer and we are hooked up to the same DSL line?
