How do I fix Failed to create D3D or D3D9 device error?

Before you even venture into our recommendations, you should restart the computer. A restart is a general fix but may be effective. It will force a few processes to stop and may help fix a failed to create d3d device error.

1. Verify the integrity of game files

Valve has kindly baked into Steam the option to check if your game files have become corrupted or if something is missing from the game installation directory. This can help if your antivirus or antimalware software has decided to block or quarantine a file. If the Failed to create D3D device or D3D9 device errors have been caused by an error of the graphics driver, giving the system a fresh start might solve the issue.

2. Update Windows to the latest version

Keeping your Windows operating system up to date is essential because you benefit from the latest bug fixes and security updates. Sometimes, these updates include compatibility patches which can fix mishaps like the Failed to create D3D device or failed to create D3D9 device errors.

3. Update your graphics drivers

3.1 Updating Nvidia graphics cards

3.2 Updating AMD graphics cards

One of the best ways to fix the failed to create D3D, or D3D9 device error is to update your graphics driver. SPONSORED These errors are caused by a problem with the graphics card or its driver, so a driver update will usually be the solution. To go one step beyond, we strongly recommend performing a clean install of the graphics driver or using a utility like DDU to remove the graphics driver altogether before installing the new one. Note: If you use DDU to uninstall your graphics driver, you must go to the graphics card manufacturer’s website and manually download either the driver or the graphics software (GeForce Experience or AMD Adrenalin).

4. Set game launch options

Note: instead of 1920 and 1080, use your monitor’s native resolution. This will force the game to launch with the specified resolution. Unfortunately, some of these games are a bit older, so they don’t always cooperate with newer hardware and higher resolutions. This can cause a problem when the game tries to launch with a low resolution, so you will need to force the desired resolution.

5. Run the game in compatibility mode

Once you have enabled compatibility mode, you can launch the game, which should clear the Failed to create D3D or D3D9 device error.

6. Enable services

In pursuing more performance, some users disable certain services that they deem unimportant. Still, we cannot stress this enough: you should never disable these if you are not 100% sure of the changes you are making, as this could lead to game crashes or, even worse, system instability. These fixes will help you fix both Failed to create D3D device and Failed to create D3D9 device errors when launching games on Steam.
