alrightangel Right, that's the error I mentioned you might see, which is why I linked the Intel guide to getting around it.
When you moved the Sims 4 folder to the desktop to allow the game to generate a new one, did you test a new save, or did you only play with your existing save? If you haven't tried a new save yet, please do, and further, use fresh sims you create yourself and place them on a default EA lot. (As in, don't use any content from the Gallery or your own library.) The question is whether the lag is limited to your main save.
If the new save is affected, please try playing in a clean boot:

The one service to leave enabled is the EABackgroundService, which the EA App needs in order to run. Disable the rest as described.
When you reboot your computer, go through the Task Manager's background processes list shutting down any service that doesn't absolutely need to be running, for example anything from MSI Afterburner to RGB software might still be enabled. If you accidentally kill a critical process and it doesn't restart on its own, just reboot your computer again.
Don't open anything other than Sims 4 and the EA App while testing, not even a browser window.
If this helps, you can selectively reenable services until you find the culprit, then either leave that disabled or (if it belongs to an app you want to keep using) let me know what it is so we can try to fix the underlying issue. If it doesn't help, try again but with your laptop offline.
