@vorkes The Sims 4 crashes in your dxdiag have to do with a component of Windows that handles text strings in different languages than what Windows is currently using. So I could see how this might impact Sims 4. The first step is to run a couple of basic checks on your Windows system files:
- 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, hit Windows key-i, select Update & Security, and click the button to check for updates. If any install, restart again afterwards.
If you still can't play, please look at the config file for Sims 4 and see whether your 3070 ti is listed as found and supported. If it is not, please stop here and paste the "Graphics device info" section of the file (only about 15 lines; I don't need the rest) into a reply here.
If your 3070 ti is properly recognized and you still can't play, please try repairing the game: open your Origin game library, right-click on the Sims 4 icon, and select Repair. If that doesn't help either, please try changing the game's language, which you can do by right-clicking and selecting Game Properties > Advanced Launch Options. Even if you don't want to play in another language, it would be useful to know that, for example, the game works in English but not Korean, or vice versa.
