I don't really know. I can't seem to find it in my device manager so it may be built in? i have a Dell laptop with intel 965 chipset.

Alas, updating my drivers did not fix the problem. I will pursue it at a later time.

Thanks Drakon. By fluke (I was looking for the Riverview file again) I saw something about disjointed sims in CAS. Of course disjointed was the word that would have described it perfectly. So I will post the info here in case anyone else has the same problem.

This is the link to the solution post.

I however needed to get a driver specifically from Dell so I went here.

I am just going to reboot to see if I did it correctly.

This was happening when I originally installed TS3 (retail) and installed with mods including Awesomemod. So I removed everything and restored awesomemod and it still did it. So I did a complete clean install of my whole computer (it needed it anyway), installed TS3 again with awesomemod and it still happens. In CAS, the slider won't make the sim fat right away, the body splits with the top half going one way and the bottom the other way. If I tab through my open screens and come back, it seems to reset the slider and my sim appears fat. Then when I save and put that sim into a lot, the sim looks thin again. If I zoom in, the body splits and still no fat sim.

What could the problem be?
