@GreaseBones96 Your dxdiag lists a number of Origin errors. While those errors shouldn't directly interfere with Sims 4, if Origin is using too much of your system resources, it could definitely affect in-game performance. So please do a clean uninstall and reinstall of Origin:
- Quit Origin, then right-click on the Task Bar and open the Task Manager. Scroll through looking for Origin entries. If you find any, click on them and End Task.
- Clear Origin's cache.
- Download Revo Uninstaller (the free version is fine) from here.
- Launch Revo, select Origin from the list, and click Uninstall.
- When it finishes uninstalling, select "Moderate" under "scanning modes," and click Scan.
- If Revo finds any remaining registry entries, select all, delete, and click Next.
- Revo will display "Remaining Data and Folders." Select all of them except for the "Origin Games" folder, if it appears. (This is where Sims 4 and other Origin games are installed by default.) Delete the rest.
- Close Revo, and restart your computer.
Next, download the full Origin installer and run it. Here's the direct download link:
http://download.dm.origin.com/origin/live/OriginSetup.exe
Be sure to run both the installer and Origin itself as an admin: right-click on each and select "Run as Administrator."
If you see the same dropped actions even when there are no stairs involved in the sim's routing, please restart your computer and try again, this time putting Origin in offline mode before opening the game. And again, the stairs issue is a known bug; there isn't really anything you can do about it.
By the way, you'll get better performance overall if you plug your monitor directly into the graphics card rather than into the motherboard.
