Weird visual glitching

@sw33tpinkbabi  I don't know what to tell you, unfortunately.  You could try an older driver; the Nvidia download page has drivers going back to March.  You'd need to DDU the current driver in order to install an older one, but you can install a newer one than whatever is already present over the top without DDU.  So if you want to try a few different versions, start with the oldest that would work for you and go forward from there.

You can also try a clean boot if you're interested:

The one service to leave enabled is the EABackgroundService, which the EA App needs in order to run.  Disable the rest as described.

When you reboot your computer, go through the Task Manager's background processes list shutting down any service that doesn't absolutely need to be running, for example anything from MSI Afterburner to RGB software might still be enabled.  If you accidentally kill a critical process and it doesn't restart on its own, just reboot your computer again.

Don't open anything other than Sims 4 and the EA App while testing, not even a browser window.  If this helps, selectively reenable services until the problem returns, and you'll know what's interfering.

Hello,

I updated to the latest game version yesterday. There was an update to one of my graphic cards, so I ran that as well. This morning I was playing the game for the first time since the update and I'm having terrible lag again since the previous update to dx11. Uninstalling and reinstalling the drivers helped previously, but has returned since this newest update. After the last update, I've uninstalled and reinstalled the graphic drivers 4 times. I even took it to have the hardware tested and they clean uninstalled and reinstalled the drivers as well. Now with this latest update, the issue has returned. 

So far I have updated the BIOS and the Firmware and scanned for errors. Since updating the Bios and Firmware, I ran a dxdiag and it's showing a memory leak with The Sims 4. 

Here's the results of my DISM and SFC: 

PS C:\Users\*> DISM.exe /Online /Cleanup-image /Checkhealth

Deployment Image Servicing and Management tool
Version: 10.0.22621.2792

Image Version: 10.0.22631.4391

No component store corruption detected.
The operation completed successfully.
PS C:\Users\*> sfc /scannow

Beginning system scan. This process will take some time.

Beginning verification phase of system scan.
Verification 100% complete.

Windows Resource Protection did not find any integrity violations.

I've also attached my dxdiag. I just wanted to add that I ran Windows Memory Diagnostics and it came back with no issues. 

@sw33tpinkbabi  The memory leak error is not uncommon in Sims 4 and doesn't typically cause the kinds of problems you've been seeing.  I wouldn't worry about it.

Does switching back to DirectX 9 currently help?  The option is with the other graphics settings.

Separately, as a test, try running Sims 4 on the Intel graphics chip.  Performance will be significantly worse than it would be on the Nvidia GPU if the game were working properly, but it should still run fine on medium-high to high settings at 1080p, so you can get a sense of whether the problem is limited to when the game is using the Nvidia chip.  Open Windows Settings > System > Display > Graphics settings, click Browse, choose TS4_Launcher_x64, and select the power-saving option.  Do the same for TS4_DX9_x64 and TS4_x64.

You can see whether this worked by opening Config.log, inside Documents > Electronic Arts > The Sims 4, and scrolling down to Graphics device info.  (Launch the game once after making any changes so that the file updates.)  Whichever GPU is listed is the one the game was using when it loaded, at least.  If you're still seeing the Nvidia card, right-click the desktop, select the Nvidia Control Panel, choose Manage 3D Settings > Global settings, and choose the Intel iGPU.  This will affect all programs, so you'll want to undo the setting later, but it's a quick and easy way to test.

Running on the Intel chip, Sims 4 should default to DirectX 9 mode, which may not work well on the Intel chip for completely separate reasons.  To force DX11 mode, open your EA App game library, click Sims 4 > Manage > View properties, and add -dx11 in the command line box.
