Best Advice on Playing Sims 3?
I have a PC with Windows XP; I recently asked for advice from EA Games about The Sims 3 because it was lagging on my PC a lot since Late Night was released. I had sims 3, sims 3 world adventures and sims 3 ambitions and all played fine without any problems. But once Late Night came, I installed it and it’s lagged ever since. EA said it’s because my graphics card is dated to 2004; I asked them any advice that could make it run better but they never got back to me. So I’m here asking for help. Is there anything I can do to make it run better? Switch background stuff off? Or…anything? I haven’t got enough money at the moment to buy a new graphics card, so that will have to wait. Any advice would be great.

Make sure you defragment your hard drive, check your PC for viruses, and clean up your computer using CCleaner. It’s free.
Download Gamebooster, it will get rid of all the unnecessary background apps that your computer is using.
