When you’re playing a game, a sudden error message interrupts you. This will make you very annoyed.
The “Unreal Engine is exiting due to D3D device being lost” error is a common problem. It isn’t a problem with a particular game. And you’re not the only one bugged by the error.
Don’t worry, they can be fixed.
Try these methods:
You don’t have to try them all; just work your way down the list until you find the one that works for you.
- Update Unreal Engine
- Update device driver
- Change the default graphics card
- Verify files in Steam
- Repair corrupted system files
- Disable NVIDIA Geforce Experience Battery Boost
- Reduce PC’s energy consumption
- Disable antivirus software
- Check hardware
Method 1: Update Unreal Engine
Developers of Unreal Engine will continue to release new versions. The new version will fix mistakes that may cause this error. So you should try installing the latest version to see if this fixes the error.
Hopefully, it does. But if not, there are still a few things to try.
Method 2: Update the device driver
Updating drivers is a useful method to solve many issues. It’s worth trying when you meet issues. According to users, if the graphics card/video card driver is outdated or corrupted, it may cause this error.
There are two ways to update your driver–manually and automatically.
Option 1 — Manually: To get your device driver, you need to go to its manufacturer’s website, find the driver corresponding with your specific flavor of Windows version (for example, Windows 32-bit), and download the driver manually.
Once you’ve downloaded the correct driver for your system, double-click on the downloaded file and follow the on-screen instructions to install the driver.
Option 2 — Automatically (Recommend): If you don’t have the time, patience, or computer skills to update the driver manually, you can do it automatically with Driver Easy.
Driver Easy will automatically recognize your system and find the correct driver for it. You don’t need to know exactly what system your computer is running, you don’t need to risk downloading and installing the wrong driver, and you don’t need to worry about making a mistake when installing.
- Download and install Driver Easy.
- Run Driver Easy and click the Scan Now button. Driver Easy will then scan your computer and detect any problem drivers.
- Click the Update button next to the selected driver to automatically download the correct version of that driver, then you can manually install it (you can do this with the FREE version).
Or click Update All to automatically download and install the correct version of all the drivers that are missing or out of date on your system. (This requires the Pro version which comes with full support and a 30-day money back guarantee. You’ll be prompted to upgrade when you click Update All.)
If you need assistance, please contact Driver Easy’s support team at firstname.lastname@example.org.
Method 3: Change the default graphics card
In order to have a better gaming experience, some people may install a dedicated graphics card on their PC. However, due to the limited performance of the integrated graphics card and the game may not be compatible with the dual graphics card, it may cause the “Unreal Engine is exiting due to D3D device being lost” error. In this case, you can set your dedicated graphics card as the default graphics card to fix this error.
- Run the NVIDIA Control Panel. Click Manage 3D settings.
- Under the Global Settings tab, choose High-performance NVIDIA processor in the drop-down list.
- Click Apply.
- Restart your PC then run the game to check whether the error will appear or not.
Method 4: Verify files in Steam
If this error occurs when you’re playing games in Steam, you can try verifying files to solve the error.
- Run Steam, click Library.
- Right-click on the game that you can’t play because of the error and click Properties.
- In the Installed Files tab, click VERIFY INTEGRITY OF GAME FILES.
Wait until it is complete.
- Relaunch the game to check whether the error will appear or not.
Method 5: Repair corrupted system files
Sometimes corrupted system files and hardware issues will lead to all kinds of errors. To identify the cause and repair it, you don’t have to check those components one by one but perform a quick automatic system scan.

If this doesn’t solve your issue, move on to the next fix.
Method 6: Disable NVIDIA Geforce Experience Battery boost
There’s a situation where you play games smoothly on your charged laptop. But the error occurs when your laptop is uncharged. In this case, you can try this method to solve the error.
But this method only supports users with NVIDIA GPU.
- Run NVIDIA Geforce Experience. Download it from the NVIDIA website if you don’t have it.
- Click Games and then disable BATTERY BOOST.
- Relaunch your game. They should be working fine mostly.
Method 7: Reduce PC’s energy consumption
In order to improve the gaming experience, people usually adjust their settings to the highest mode. However, this will lead to an overloaded computer with excessive energy consumption which may cause the error.
So, reducing high energy consumption settings may help you solve the error. It includes turning down all the graphics settings to the lowest and underclocking your GPU.
If you’re overclocking the GPU, you can try to underclock it. There are users who are able to play a stable game by underclocking their GPU.
Also, turning down all the graphics settings to the lowest can help your game run smoothly.
Method 8: Disable antivirus software
It is possible that your antivirus software might have a conflict with Unreal Engine. So try to disable your antivirus and then run the game to check whether the error will appear or not.
If it does fix the error, you may consider changing your antivirus software. Or, you can ask your antivirus manufacturer for advice.
Method 9: Check the hardware
In some cases, problems can be caused by your computer hardware. It’s worth checking the hardware devices on your computer.
Our reader shared that a bad RAM stick would cause the issue and crash the game. In his situation, the MEM test and Windows mem test didn’t spot the issue but removing the bad RAM stick solved the problem.
We suggest people reboot your computer and then perform the Windows Memory Diagnostic tool to test your RAM first. If the test gives you errors, you need to check your RAM stick or replace it.
We recommend you contact the PC manufacturer for your device for help if you discover any hardware issues (e.g. a bad RAM stick). But you can always do it by yourself since there are lots of tutorials on the Internet. Note that the process should be cautious.
We hope the above methods can help. If you have any questions or suggestions, feel free to leave comments below.
