Sims 4 at regular intervals fps drop

aydiinyilmaz  As a test, please try playing with your computer completely offline.  You can login to the EA App and put it in offline mode, then disable wifi and/or disconnect the ethernet cable before pressing Play.  This isn't meant to be a solution but rather a useful diagnostic test.

If you see the same issue, please provide a dxdiag.  Click Windows key-R, enter dxdiag in the run box, wait for the scan to finish, click "Save all information," and save the file to your desktop.  From there, you can attach it to a reply using the paper clip (Attachment) icon included with the other formatting buttons.

If the game works while your computer is offline, try playing online but with the EA App in offline mode.  If that works too, keep the App online but disable Sims 4's Online Social Features setting, under Options > Game Options > Other.

Thank you very much for your answer, but the situation is still the same. I turned off all my internet connections. However, a second lag appears every 3-5 minutes. Can anyone test this for me via afterburner? I observe the same thing on both computers at home. Still, I leave a document here. What I've tried: Clean Install. Testing without mods. Testing without internet connection. 

aydiinyilmaz  Do you use the same antivirus on the old and new computers?  If so, please try disabling it, temporarily of course, to see whether it helps.  As long as you don't do anything else at the same time, your computer should be safe, and you can still test while offline if you want.

If that doesn't help, 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.
