Horse Ranch Lagging

@KathBoss25  Does this happen in a new save in a clean folder?  Please test:  Move the entire Sims 4 folder out of Documents > Electronic Arts and onto your desktop, and when you launch the game, a clean folder will spawn with no content.  (Your saves and other content will be intact in the folder you moved but temporarily not read by the game.)  Don't add anything to the new folder yet; just start a new save and let me know how it runs.

If the new save is fine, try adding one of your old saves to the new folder, but nothing else yet, and test that too.

Please also run a dxdiag and attach it to a post.
