Re: Low FPS/Windows 11
@hilderstone Just to cover all the bases, please try playing a new save in one of the base game worlds, in a clean user folder. Move the entire Sims 4 folder out of Documents\Electronic Arts and onto your desktop, and the game will spawn a new folder with no content the next time it loads. Don't add anything to it yet; just see how the new save runs. And make sure vertical sync is disabled in the graphics options.
If you use a third-party antivirus, please try disabling it while you play. You can do so with your computer offline if you prefer, but even if not, your computer should be safe as long as you only open Origin and Sims 4.
Please also run a dxdiag and attach it to a post.
