@DapperPaperBagSF The Sims 4 errors in your dxdiag are most likely related to the driver for your graphics card. However, the dxdiag crashed four separate times while running, which suggests there are some significant system issues that need to be addressed. So it's best to start with a couple of basic checks of your Windows system files. Here's how:
- Hit Windows key-X
- Choose either “PowerShell (Administrator)” or “Command prompt (Administrator),” whichever option is offered
- Inside the window that appears, copy and paste “DISM.exe /Online /Cleanup-image /Restorehealth” without quotes into the window, and enter
- The system will start validating soon. If it throws an error, please list it here
- After it reaches 100%, hit Windows key-X again
- Again, choose “PowerShell (Administrator)” or “Command prompt (Administrator)”
- Inside the window, copy and paste “sfc /scannow” without quotes into the window, and enter
- Post the message you receive here
Restart your computer, and run another dxdiag and attach it. (You can attach the new one to a reply, rather than the first post; that will make it easier for me to compare the two.) The first dxdiag didn't even list your current Windows build, among other things, and I'd rather see all the relevant information before suggesting anything else.
@Psychotps While the game might not respond well to an alt-tab in fullscreen mode, it shouldn't consistently freeze. And it should never freeze from an alt-tab out of windowed fullscreen. That's kind of what that setting is for.
