Re: Base game The Sims 4 Steam edition keeps crashing
@djf149 This crash lists a component of the Nvidia graphics driver (nvwgf2umx.dll) as the faulting module, but DDU should have taken care of any driver-related issues. Have you overclocked your GPU, either manually or with the tool built into GeForce Experience? If so, please revert to stock settings and test again. If that doesn't help, and you've overclocked your CPU, revert that as well.
If that doesn't help or isn't relevant, do you have another graphics card you could test with? I'm not saying your RTX 4090 is defective, only that it's worth testing. You would need to DDU the Nvidia driver if you were installing an AMD GPU but not another Nvidia card.
If you don't have anything else to test with, you could remove the Nvidia GPU entirely and plug your monitors into the motherboard. The Intel iGPU would take over, meaning performance would be significantly worse, but it would still be a good test. Your computer already has the Intel graphics driver installed.
And I realize this might sound extreme when only one game is crashing, but the errors I've seen have been very clear. And if it were purely a defect with Sims 4, we'd see a much larger number of posts about it.
