CurlyCurls21 Is Sims 4 actually using the RTX 4060? Please open Config.log, inside Documents > Electronic Arts > The Sims 4, scroll down about 30 lines, and check the GPU listed there.
If you don't see the 4060, please tell me what's there, and also 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.
Either way, I'd also like to know what you mean when you say that your "graphics go down the toilet." Post a couple of screenshots if it's easier.
