Go to my studio to see another example.
At first I thought it was just the drivers being out of date. After checking and upgrading what needed upgraded the demo was still as glitched as ever. It wasn't until a few days after that I found someone else with the same graphics chip, the Intel G33/G31 Express Chipset Family, with the same issue. For me this sent up red flags. It could very well be just the demo, but there is a possibility it might be in game as well. The chip has played Sims 3 and all of the expansions, so that shouldn't be a problem. I'm just here to point out the possibility to anyone. That way if there is a problem it can hopefully get fixed. Having to end getting the new EPs because of a problem with a certain graphics card isn't exactly ideal. I will still be getting the game, but it'll feel like wasted money if this issue carries over.
On the bright side the other that had this same issue has Windows 7 and I have Vista. This means it isn't just a problem with Vista. Before anyone asks neither of us has any custom content so that isn't the problem.
Edit: G33/G31 Glitch - 4
Nvidia GeForce 6200 Glitch - 1
Nvidia GeForce 6150SE Glitch - 1
ATI Radeon Xpress 1250 Glitch - 1
Edit2: It seems the Nvidea 6200 has a similar problem.
Edit3: The Nvidia GeForce 6150SE doesn't render the heads of the cats and dogs properly, instead going grey. The ones loaded upon selecting what to create/upon CAP start up seem fine though.
Edit4: The ATI Radeon Xpress 1250 doesn't work either.
