How To Fix League of Legends GPU Error (DirectX Error) in a Few Steps

It appears that the DirectX error has something to do with the graphics card drivers and the DirectX version that is installed. The LoL DirectX Error is responsible for managing the interface between video games and audio/video hardware in the Windows operating system. An error with DirectX can cause applications that use the software to stop functioning correctly, and here's how to fix it.

How to Fix League of Legends DirectX Error?

There are a number of fixes you can try in order to get rid of this error. If one doesn’t work out you can always move to the next, and so on. It’s best to try them all out and see if it works for you.

These fixes vary depending on whether they address the error message through your operating system or through your graphics card.

Re-Enabling Video Card Drivers

In its essence, this error message is caused by a problem with your graphics card. After all, a video card is the most important part of your PC when it comes to running League of Legends. So it isn't too far of a fetch to assume that a quick way to fix League of Legends on your PC is to, in essence, reboot the graphics card. You must find your video card/graphics card in the Device Manager and then select it.

Uninstalling the Graphics card should reset and re-enable the video card drivers and hopefully fix the League of Legends DirectX error message that is popping up.

Delete the game’s sub-files

One method to fix the graphics card DirectX error is to delete League’s subfolders and subfiles. After you’ve deleted the subfiles, you must initiate a Repair using the game’s repair tool, and this should fix the files and remove the error.

Begin by opening the Config folder from the main LoL folder, and delete the game.cfg and input files.

Next, go to the RADS subfolder. Here, you need to select lol_game_client_en_us and lol_game_client subfolders. After selection, right-click and then Delete them. Now that you’ve deleted the subfolders/files, you need to perform a repair. In order to do this, open up the game and press the question mark(?) icon on the top-right. Select Repair from the list of options and wait for it to end.

Delete the Game.cfg

Another way to remove the LoL DirectX error is by directly deleting the Game.cfg file. Many players have been successful in removing the error in this way. Some players have also reported having deleted the Config subfolder as a whole, but its safer to only stick with the file. The game.cfg is in the Config folder within the LoL game folder.

You can find the location of your LoL folder by right-clicking on the LoL icon on the desktop and selecting Open file location. Once you're in the folder, go to the Config folder and delete the game.cfg file. Check if the error has been resolved or not.

Update Graphics Card Driver

Your Graphics drivers and DirectX work hand-in-hand in order to provide the optimal gaming experience. Therefore, the League of Legends DirectX error could be the result of an outdated or faulty Graphics Card Driver. You can use the following steps to update your GPU drivers.

Go to the Device Manager by right-clicking on This Computer and then selecting properties. Select the Display adapters and right-click your GPU, then select Uninstall device. After that, click on Delete the driver software for this device, and finally, select Uninstall. Then, download the latest version of your GPU driver from the official website of the manufacturer.

Alternatively, if you’re using Windows 10/11, you will probably get the latest hardware drivers when you update Windows. So, always keep a check if an update is available or not. You can check for Windows updates by searching for Settings in the search bar. Click on Windows Update and select Check for updates. Install if any new updates are available.

Roll Back a Driver to an Earlier Version

Many players have noticed that the issues started appearing only after they updated their GPU drivers. This might be due to the new drivers not being entirely compatible with your device. If you are in a similar situation, you might want to consider rolling back to a previous version of your Graphics Card Driver. Follow these steps;

1. Go to the Device Manager through the search tab, go to Display Adapters, right-click on your video card, and select Properties.
2. Move onto the Driver tab, and choose Roll Back Driver. Follow the subsequent instructions to roll back to the previous version successfully.

If the Roll Back option is unavailable, your drivers have not been updated in the last few days.

Repair the .NET Framework

The .NET Framework is a prerequisite for DirectX to function properly. Any issues with the framework could lead to DirectX errors. This fix is beneficial for an older Windows operating system. Download and Install the Microsoft .NET Framework Repair tool and simply repair the Net Framework using the tool.

Install DirectX Again

One of the most efficient methods to fix the DirectX issue is to reinstall it by deleting the registry key. Here's what you'll need to do:

1. Press Win+R and type “Regedit,” and press Enter.
2. Go to HKEY_LOCAL_MACHINE\Software\Microsoft\DirectX. Here, you need to select and Delete the DirectX folder. After this, hit the confirm button and restart your PC.
3. After this, you need to re-install DirectX on your PC. DirectX can be downloaded from Microsoft’s official website, or if you’re on Windows 10 or above, it will be automatically downloaded as soon as your PC restarts.

This should, in theory, stop the League of Legends DirectX Error from popping up when you boot up the game.

Reinstall League of Legends

If all the other methods to fix League of Legends on your computer fail, you can try one final thing. The final solution to fix League of Legends is reinstalling League of Legends on your PC.

This should reset any glitches from the game settings or how the way the game is internally communicating with the directories on your computer. And while you’re waiting for League to download again, you can head over to freecash.com to pick up some skins for your characters, entirely free. 

These are some of the popular fixes that can be applied to deal with the DirectX error. Many players in the LoL community swear by these tactics that have worked for them. Try them out and see what works best for you!
