I tried everything

@katelynwstxoxo  Your dxdiag shows a few generic Windows errors, so it's a good idea to clean those up before proceeding.  Please 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, 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, 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.

To set a baseline for performance, please test a new save in a clean user folder.  Move the entire Sims 3 folder out of Documents > Electronic Arts and onto your desktop.  If you get an error when trying to move the folder, or it copies instead of moving, please stop here and let me know.

Otherwise, the game will create a clean folder with no content when you open the launcher.  Don't add anything to this folder yet; just start a new save in Sunset Valley and let me know how it runs.  Please also confirm that your in-game framerates are locked to 120 (the refresh rate of your laptop's screen), or whatever limit you've set.  You can see the values with the cheat fps on , and the fps counter will appear in the upper-right corner of the screen; fps off will make the counter go away.
