I have also been having the same problem as the rest. I'm running the Home Edition of XP on a sytem with a Pentium 3.2GHz, 1.50 GB of RAM, 80 Gb free on the hard drive. I had the 128mb Radoen 9200. I started out by upgrading to the 256mb Radoen x800. I've tryied re-installing the most current graphic drivers, the Sims 2, and DirectX v9c. I have checked and my smoothvision is set to application preference. My Refresh rate is set to the maxium rate my screen can handle and the games refresh rate is set to the same. I have downloaded and installed the patch from the Sims2. But I'm still getting graphic problems with the sims heads dissapearing. Can anyone help?
