Here's an older thread I found. Maybe that helps

That was really helpful! It seems I have to change the smooth edge settings, the problem is that mine is grayed out. Maybe the onboard graphic card is not enough :/
I will keep looking for a solution now that i know what to look for. Thanks!
I had a similar graphic problem with my Origin Ultimate Collection which I solved by changing the smooth edge settings to high.
My smooth edge settings were grayed out but this can be changed by editing the "Graphics Rules.sgr" file.
The file can be found in the following directory (Win 7 / Win 10):
Documents / Ea Games / The Sims 2 (Latest Expansion or Stuff Pack installed) / TS Data / Res / Config
Copy the file before changing it!
Open the file with a text editor e.g. "Notepad" and press ctrl + F to search all appearances of "enumerateMultisampleLevels" and change "false" to "true".
Make sure each time "enumerateMultisampleLevels" appears it has "true" next to it.
Then you can start the game and change the settings to high.
After that, I had no more problems.
I did try doing that but it always went back to false
You need to save it when your done. You can’t just exit.
