lines and or squares on walls during game play

[lilsweetiecori]

Hi there, I searched and I didn't see this problem so I wanted to post. My game runs fine but I notice there are lines and squares on my walls. It doesn't have to do with custom walls, I checked that. I also checked my games on another machine with different monitors and different graphics cards and it is still a problem. It happens with all EPs and it happens with only the base game. Here are some screens

I did post this in the Computer & Tech Gizmo Discussion part on the sims 2 community because I at first thought it was a graphics problem. I now think it must be a game problem. Here is the thread if you would like to read...

Any help with this problem would be greatly appreciated!!

EDIT: It seems to be a problem with the shading?...

This is the Goths house, all I did was add the green Maxis walls to the outside to see what plain walls looked outside. I kept the original maxis walls in the inside. Notice how there are no lines on the green walls but there are on the gold. Why isnt the oustside of the house affected like the inside?
