Jagged lines in Sims 4

@littlemissday  I meant to say Program settings, since I don't know what other games you play and whether you'd want those affected too.  For the purposes of this thread, you could use either one, but if you're still using global settings, please make sure that you haven't changed any of these settings for TS4_x64.exe, since explicitly set program settings will override global ones.

I don't know whether it's directly related, but your dxdiag also lists quite a few BlueScreens that are related to the video scheduler.  So it's a good idea to clean uninstall and reinstall the Nvidia graphics driver.  First, to cover your bases (in case this is on the Windows side rather than the driver side), run a couple of basic checks of your Windows system files:

• Hit Windows key-X
• Choose either “PowerShell (Administrator)” or “Windows Terminal (Administrator),” whichever option is offered
• Inside the window that appears, copy and paste “DISM.exe /Online /Cleanup-image /Restorehealth” without quotes into the window, and enter
• The system will start validating soon. If it throws an error, please list it here
• After it reaches 100%, hit Windows key-X again
• Again, choose “PowerShell (Administrator)” or “Windows Terminal (Administrator)”
• Inside the window, copy and paste “sfc /scannow” without quotes into the window, and enter
• Post the message you receive here

Restart your computer, hit Windows key-i, select Update & Security, and click the box to check for updates.  If any install, restart again afterwards.

Here's how to clean uninstall and reinstall the driver:

You can download a fresh copy of the Nvidia driver here:

You'll need to redo your Control Panel settings afterwards.

I do want to say that if you're hoping to make Sims 4 look perfect, you're never going to get there.  It always has some mild aliasing, that's just how the video engine works; it's a question of improving things as much as possible.
