Re: Sims 4 crashes repeatedly
@fernlocke Thanks for the dxdiag and for already doing so much testing. There are a couple things you didn't mention that are worth trying, if you haven't already. One is to play with no peripherals connected to your laptop, not even a mouse. Restart after disconnecting the devices and before trying to play.
Another is playing in a new admin Windows account. Make it local, as in, don't link it to your Microsoft account. This will cover any potential issues limited to your main account and is a helpful way to narrow things down a bit. I would suggest trying a clean boot there too, as you've done before, just to be thorough. If you've already tried it and it didn't help, let me know.
Your dxdiag also shows a couple of crashes of a component of the intelliGo Audio Service, which likely came pre-installed on your laptop. While a clean boot would normally disable this, it's possible the service is entwined tightly enough with your Realtek sound driver that it keeps running. You can uninstall it through the Device Manager if you want to be sure it's not a problem.
I don't know that these crashes happened at the same time as you were playing though. If you want to find out, open the Reliability Monitor (Windows key-R, perfmon /rel ) for recent crashes that happened while you were playing. The component in question is iGoSwServer.exe; if it crashed when Sims 4 did, that confirms it's involved in some way.
One somewhat random suggestion I have that's easy to test is to force-limit the game to 60 fps. You shouldn't need to, and your hardware obviously can handle a much higher load, but it's possible the game engine is the problem and not anything specific to your system. It's more likely that this is unrelated, but as I said, it's a simple test. Go into Documents > Electronic Arts > The Sims 4, open Options.ini, search for frameratelimit , and set it to 60. You can always undo the setting later.
While you're there, force the game to run in windowed mode as well. If you can't open the options at the Main Menu, you can edit Options.ini to set fullscreen to 0 (zero).
Please test using a new save each time, if you can get that far, and still with no mods or custom content; and keep using the new Windows account until the game is stable again.
