DirectX / Direct3D Error Fix
This error is common for players who are running older GPUs that do not support the new Windows 10 DirectX. However, players running newer GPUs are also reporting this error and hence it is not just limited to older GPU users.
It likely means that either your computer has an outdated version of DirectX or you have some kind of graphics card issue. To fix the problem, do the following:
1. Restart Your Computer and the Game
Sometimes strange things happen to computers. So, the first thing you should always try is rebooting your computer. Then, try to run the game again.
2. Install Any Updates to the Game and to Windows
Back 4 Blood often releases updates and patches. Check to see if there is an update available for the game at the site where you downloaded it. If there is, install it and follow any subsequent instructions, such as rebooting your computer.
You may also want to update Windows if there are any updates waiting to be installed.
3. Install or Update Your Graphics Card Driver
Sometimes a missing, corrupted, or out-of-date graphics card driver can cause the error message. To update the graphics card driver in Windows 10, do the following:
Click the Start button, and in the search bar type Device Manager, and then select this from the list of options.
Expand the Display adapters category, right-click the name of your graphics card and choose Update Driver.
Choose Search automatically for updated driver software.
If no driver is found, you can search for one on the website of the graphics card’s manufacturer, and then follow its instructions for installing it.
If for some reason updating the driver does not work, you can try reinstalling the driver by doing the following:
- Like in the previous steps, open the Device Manager and right-click on the name of the graphics card.
- Restart your computer, and Windows will attempt to reinstall the graphics card driver.
4. Install the Latest Version of DirectX
DirectX is a Windows API that lets you run 3D software on your computer. Often Microsoft updates this API and game developers such as Epic Games make use of the changes to improve their games. Because of this, you need to periodically update your version of DirectX.
To check what version of DirectX your computer is using, click the Windows key and the R key at the same time. This will open the Run dialog box, and from there you should type dxdiag and click OK. This will open the DirectX Diagonsis Tool.
On the System tab, you will see the version of DirectX installed on your computer, and from the Display tab, you will see the Feature Levels installed. To run Back 4 Blood, you need to have at least DirectX 11 and feature levels 10.0 installed. If you have an older version of DirectX, you need to download and install the latest version of DirectX.
