Texture gltiches

@charaaasweet  If you use any mods or custom content at all, please remove it.  Even if it works fine with the iGPU running Sims 4, it's still worth testing without that content.

When you uninstalled and reinstalled the Nvidia graphics driver, did you use the driver from your laptop's manufacturer or directly from Nvidia?  Whichever one you tried, please try the other.

If that doesn't help, please run a dxdiag and attach it to a post.

I agree with you that this does seem like a GPU issue, but that covers several different issues, and there might be a way to fix this depending on the cause.

I unninstalled the Nvidia driver in device mananger as well as making sure to check the box "delete driver software". Without the driver initialised it would automatically run through intergrated graphics and this worked.

I then did Scan for hardware changes and used the inital driver to run the Sims but got the texture issues again. Downloaded the newest Nvidia driver and installed but yet still ran into the issue. I even tried to use an older driver update to see if there was compatibilty issues with newer updates but this did not help.

@charaaasweet  Your dxdiag shows new errors relating to the Nvidia graphics driver, likely from after you reinstalled the driver.  So please do a clean uninstall and reinstall of the driver, as described here:

This process is more thorough than uninstalling through the Device Manager, which is why the tool exists.

Instead of downloading the newest driver from Nvidia, I'd suggest using one from December 8 or January 5.  (These didn't produce any Sims 4-related issues as far as I saw on this forum.)  You can find slightly older drivers here once you manually select your GPU:

Used DDU as suggested but the problem remains.

After reboot I ran the Sims and everything was working fine but after opening task manager I realised that it was running off the CPU.

There was an Nvidia task running in the background, it was self installing a driver update, version 320.18. I ran Sims after this had completed but was hit with the same graphical glitches.

I ran through DDU again and after reboot I installed the Nvidia update from December 8th but the issue remains and I repeated the process for the January 5th update.

@charaaasweet  The Nvidia card might in fact be the problem.  If you want to test it, install the free version of 3DMark and run Time Spy and Fire Strike, and post your results.  (You should get a link to a web page with the results of each test.)  When you run each test, restart your computer immediately before hand, don't open anything else in the background, and don't touch your mouse or trackpad.
