@Pjrabbitoh This is a long shot, but if you have GeForce Experience set to optimize your Sims 4 settings, please undo that option. It's better to change your settings manually.
There are some errors in your new dxdiag that are likely related to the graphics driver, but since they're not timestamped (this is normal, don't worry), I don't know whether they're from before or after you reinstalled the driver. There are also a couple of Origin errors. So please do a clean uninstall and reinstall of Origin:
- Quit Origin, then right-click on the Task Bar and open the Task Manager. Scroll through looking for Origin entries. If you find any, click on them and End Task.
- Clear Origin's cache.
- Download Revo Uninstaller (the free version is fine) from here.
- Launch Revo, select Origin from the list, and click Uninstall.
- When it finishes uninstalling, select "Moderate" under "scanning modes," and click Scan.
- If Revo finds any remaining registry entries, select all, delete, and click Next.
- Revo will display "Remaining Data and Folders." Select all of them except for the "Origin Games" folder, if it appears. (This is where Sims 4 and other Origin games are installed by default.) Delete the rest.
- Close Revo, and restart your computer.
Next, download the full Origin installer and run it. Here's the direct download link:

Be sure to run both the installer and Origin itself as an admin: right-click on each and select "Run as Administrator."
If you see the same issue, please try playing in a clean boot:

When you've rebooted, please go through the Task Manager's background processes list looking for anything that doesn't absolutely need to be running. For example, anything with the word "Nvidia" in it should stay, and of course anything Windows-related, but other background tasks need to be shut down. While the clean boot normally addresses this, some apps still manage to run, hence the need to double-check.
