Just before getting the BV I was having a good read around and was getting worried with what I was reading, but after putting the game in both my PC and Laptop everything seams to be working fine.
My PC is windows XP, ram 512, graphic card 6600 GT Nvidia, so by putting the Sims settings on medium it working not bad at all.
My laptop is Vista, ram 1gig, 8400 Nvidia and playing fine...
One thing I would say is don't be in a rush to update you graphic card if your PC is like a spec like mine as I find it don't help and makes things worse, I had to take out one update, so I'm using 84.21 Nvidia driver.
