How do you force DirectX 11 on Steam Deck?

The Steam Deck, Valve’s newest gaming console, is capable of running a variety of games across different Windows versions, including DirectX. However, some users have reported issues with games failing to run or not having the best performance. A common solution to this is to force DirectX 11 on Steam Deck, a process that is relatively easy to achieve.

Why Forcing DirectX 11 may be Necessary

DirectX is a set of technologies developed by Microsoft to run graphics and gaming applications. Within DirectX, there are three main versions: DirectX 9, DirectX 11, and DirectX 12. Games may require certain versions of DirectX to function properly. Forcing DirectX 11 on Steam Deck can resolve issues such as:

• Graphics related problems: DirectX 12 is the default graphics architecture on Windows 10 and 11, but it may not be compatible with all games. Forcing DirectX 11 can restore compatibility with older games and improve graphics performance.
• Crashing and bug issues: Some games might crash or exhibit bugs when launched on the Steam Deck running DirectX 12. Forced DirectX 11 can ensure a smoother gaming experience for these games.
• Performance issues: Some older games might not be optimized for DirectX 12’s more powerful graphics capabilities. Forcing DirectX 11 can restore performance levels expected from older games.

How to Force DirectX 11 on Steam Deck?

There are a couple of ways to force DirectX 11 on Steam Deck:

Method 1: Using Steam’s Launch Options

1. Navigate to Steam Library: Click on the Steam icon located in your computer’s Startup menu and select "Settings" from the drop-down menu.
2. Select a Game: Search for the game you wish to launch in DirectX 11.
3. Right-click on the game: In the Steam game library, right-click on the game and select "Properties" from the pop-up menu.
4. Select the "Compatibility" tab: In the Properties window, navigate to the "Compatibility" tab.
5. Tick the box: Tick the box labeled "Run application in compatibility mode" for Windows XP (Service Pack 2).
6. Tick the box (Optional): Tick the box labeled "Force GPU rendering".
7. Save the changes: Press "Apply" and "OK" to save your changes.
8. Launch the game: Locate the game in your library and launch it as normal.

Method 2: Editing the game settings file

Warning: This method is more invasive and requires some technical proficiency. Proceed with caution.

1. Check the game’s folder for a config file: Explore the game’s folder using File Explorer. You will likely find a "Game.exe" file. Beneath it, there is a folder called "dx11". Within the folder, look for a JSON file (usually named dx11.config).
2. Open the JSON file: Using a text editor, such as Notepad++, open the dx11.config file.
3. Locate the shader model settings: Look for the line of code under the shader model section <ShaderModel>0|1|2|_3 and replace "_3" with "10" (DirectX 11). The correct form should look like `0|1|2|10>.
4. Save the changes: Save the modified configuration file.

How do I Check if DirectX 11 is working?

To ensure DirectX 11 is being used, monitor your game’s performance metrics. Common signs that indicate DirectX 11 is operating correctly include:

• Smooth graphics and reduced frame latency
• Improved frame rate and increased graphics fidelity

What are the Best Practices for Forcing DirectX 11?

Always follow these guidelines when modifying game settings:

• Backup your original files: Take a copy of your current game files before making changes to avoid data loss.

• Update your game if necessary: Check for newer versions of the game client or updates for your computer’s drivers.

• Enable compatibility mode only for troubled games: Don’t forcibly enable compatibility mode for non-troubled games or you might encounter unintended graphical issues.

Conclusion:

In conclusion, forcefully enabling DirectX 11 on Steam Deck can be beneficial for troubleshooting issues, performance optimization, and resolving backward compatibility issues. This modification is a temporary solution designed to fix specific problems that may arise. Be patient and adjust settings according to your gaming needs.

Whether you use the method requiring Steam’s launch options or editing the game settings, remember to be cautious with your system files and create backups. Additionally, for optimal results, monitor system performance, and consider revising settings if issues still persist.
