Sims 4 and DirectX
Sims 4 is being upgraded to DirectX 11 (DX11) with Patch 1.107.112. At first the new version is offered as opt-in and will be become standard in a later patch.
DirectX is a programming interface for games and other multimedia programs. It helps developers to program their software without having to support every single graphics card out there. They only need to support DirectX instead.
DirectX 11 or later comes as part of the operating system and doesn’t need to be installed separately.
More details can be found at Wikipedia.
Sims 4 currently supports DirectX 9c but the System Requirements list DirectX 11 as required.
DirectX 11 is currently available as opt-in. This will change in the future when DirectX 11 will become the new standard.

If you want to test out DirectX 11 you need to add -dx11 as command line argument.
You will then see in the main menu which version Sims is running with.
Maxis recommends to remove all your mods/cc to try it out as there might be visual issues with them.
Simply remove the command line argument you added to go back to DirectX 9
The DirectX version used by the game shows in the lower right corner of the main menu.
The upgrade should help with better graphics quality and increase the general game experience with improved render capabilities.
The opt-in looks like a test. You can report any issues at AHQ.
The changes are still in testing and there can be issues. If you have problems with text and dialogs it’s best to return to DX9 for now.
Here are a few troubleshooting steps you can try for now
- Make sure your graphics card supports DX11
- Update your graphics drivers
- Remove all Mods/CC
- Resetting the game to factory settings without reinstalling
- If the game starts with DX9 despite the option, make sure you added it to the correct place and it’s still there (EA app, desktop shortcut, Steam).
- If you have files in the folder Documents\Electronic Arts\The Sims 4\ConfigOverride, remove them and redo the changes on the current game files.
- If you still can’t get it to work, post in this thread at AHQ: DirectX 11 Technical Issues and Feedback Thread. Make sure to provide the info asked in the first post.

You can find your current DirectX Version in the DxDiag.
- Press Windows-Key + R

- Find the current DirectX Version in the system tab towards the bottom.
DirectX is backwards compatible so if you have DirectX 11 and higher you can try it out.
Currently nothing changes. At this point it’s unclear what happens when DirectX 11 is rolled out for everyone.
No. Unless you run Windows on your Mac to play Sims 4 this change doesn’t affect you.
The game doesn’t start. I only see a white screen
Remove any edited versions of the file GraphicsRules.sgr in the folder Documents\Electronic Arts\The Sims 4\ConfigOverride you might have.
If you want to keep your changes, copy the current version of the file from the installation folder to the ConfigOverride folder and redo the changes.
If you downloaded a file from another user, make sure you get the newest version from their page if available. The file must be created/updated after May 29th, 2024 to be compatible for this change.
