My sims 4 game is running slow without any mods.

SimBliss  Is there a reason you're running an old build of Windows?  18363 was released in late 2019 and lost support in May 2021.  Unless you have a specific reason not to update, that's the first step here.  If you can't run an update the normal way, a repair install will take care of it for you.  Here's how:

Once you've updated the OS, please update the graphics driver.  Your current version is from 2017, and AMD offers a driver from 2022 that should work much better.  You can find it here:

Run the installer as an admin: right-click the download and select "Run as administrator."  Restart your computer after installing and before trying to play.
