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.

Sorry for the late reply.

I have attached the DxDiag.

@hilderstone  Did you try playing with McAfee disabled?  Your dxdiag shows that one of its components has been crashing.  Also crashing are a couple of Asus services, so please disable those too, at least for now.

Usually it's enough to kill a service in the Task Manager, but if the Asus software restarts itself, use msconfig instead.  Hit Windows key-R and enter "msconfig" without quotes, then disable anything with Asus in the name and restart your computer.  Reverse the process to reenable the services.

If that doesn't help, please let me know how a new save runs in a clean folder while your computer is offline, as asked earlier.

Thank you. I have completely uninstalled McAfee and disabled as many ASUS services as I can. No resolution. Turning down object quality resolves the issue. But I don't think this is the appropriate fix as I've played with all settings set to ultra and reshade alongside it and still maintaining 60 FPS. Really confusing. Is it using my integrated GPU? This is the usage of both with Sims 4 running.

@hilderstone  Your laptop is definitely using the iGPU in your screenshot.  Did you by any chance minimize the game before looking?  That could and should prompt a laptop to switch to integrated graphics.  So could playing on battery, which I meant to mention before; if you're not playing with the laptop plugged in, please try that first.

Otherwise, you can force Windows to use the Nvidia card.  Hit Windows key-i, select System > Displays > Graphics settings, click Browse, choose TS4_x64.exe, and select the high-performance option.  This should override almost any other source trying to select the integrated chip.

Please also remove ReShade, at least for now. The fact that lowering object quality helps is odd, but maybe less so if something wonky is happening with a texture overlay.

Oh yeah, thank you. I minimised the game to check the usage for you, so that’s probably why that happened. I’ve triple checked all settings and the game should definitely be using the dedicated GPU. Other games are running as they should. I’ve upgraded to Windows 11 and downgraded back to Windows 10, issue still persists.

@hilderstone  I definitely think it's worth removing Reshade to see whether it helps; you can always reinstall it later.  Even if you have no intention of playing without it, this would be a useful test.

Sorry for not mentioning, I have uninstalled this at the beginning of doing my tests

@hilderstone  If you'd like to do some hardware monitoring and have me look over the results, I'd be happy to (although it might take a couple days before I have time).  I don't know that the log would have any useful info, but it couldn't hurt.  Download hwinfo from here:

https://www.hwinfo.com/download/

You don't need to install anything; just choose the portable version, unzip it, and launch it from Downloads or wherever you want to keep it.  (If you do want to install it, make sure to click the button for hwinfo itself, not for lansweeper.)  Restart your computer, launch hwinfo, and click the button that's a sheet of paper with a + on it to start logging.

Wait five minutes, then launch Sims 4 and play for at least 20 minutes, using your normal settings so you see the usual low framerates.  When you're done, click the same button to end logging.  You can upload the log to the third-party filesharing site of your choice (Google Drive, Dropbox, etc.) and link it here.  Please leave it in .csv format, or if you're using OneDrive to host it, zip it first.

I don't have any other suggestions at the moment, unfortunately.  There are plenty of reasons why Sims 4 can run slowly, but a new save in a base game world should be more than fine on your hardware.
