How to correct the error $ 0027Unreal Engine is exiting due to loss of D3D device $ 0027

Users experience the error message $ 0027Unreal Engine is exiting due to loss of D3D device $ 0027 when Unreal cannot connect to D3D device on your computer. This error is very common and can also occur for users who have no apparent problems on their computer.

Unreal Engine crashes due to loss of D3D device

According to the Unreal Engine developers, This problem usually occurs when the computer's hardware or graphics components are not properly synchronized with the Unreal Engine, which in turn causes a malfunction with the D3D device. In this article, We will go through all the solutions to explain why this problem occurs and also, what are the solutions to fix it.

What causes the error $ 0027Unreal Engine is exiting due to D3D device missing $ 0027?

After receiving numerous user reports about the problem, we decided to investigate it. After combining these reports, we duplicated the situations on our workstations and solved the causes. The reasons why you may experience this error message are, among other:

• Outdated Unreal Engine: the most likely cause is that the Unreal Engine is not updated to the latest version and cannot communicate with other system components that may have been recently updated. It can also be the other way around.

• Software antivirus: There are numerous antivirus programs that tend to block the malicious engine, thus marking a false positive. This is very common and can be fixed by creating a whitelist or disabling it..

• Outdated device drivers: Another likely cause of this problem is damaged or outdated device drivers. In both cases, reinstalling or updating drivers works.

• Incomplete Steam files: Steam often works with the unreal machine. If your game files / installation are corrupt or incomplete, you will see the error message being discussed.

• NVIDIA Geological Force configuration: these modules are also known to conflict with the game. Disabling the module or disabling specific settings usually solves the problem.

• Overclocking: overclocking can give your PC the boost it needs, but it is known to cause problems or conflicts with resource consuming applications. Disabling overclocking may work for you.

• Default graphics card: the default graphics card is usually disabled when running a dedicated one with more power. However, in several cases, it can be active together with the dedicated graphics card and cause conflicts that will cause more problems.

Before starting solutions, make sure you are logged in as administrator. What's more, you must have an active and open internet connection.

Solution 1: actualice Unreal Engine, Windows y Steam

As usual, if any of the mentioned components are out of date, have communication problems with each other. With bad communication, the game cannot work properly. This is a very common recurring problem and is often overlooked by users.

The method to update the Unreal engine is a bit long, but Windows and Steam update in no time. Make sure you are logged in as an administrator and follow the steps in the exact order. We will start by updating the Unreal engine.

1. Open the launcher and navigate to the library

2. Once in the library, on top, could see engine version. If there is an update available, you will see one more icon next to it.

3. Click Add Versions and, when i do, you will be prompted to install the new motor. Download the corresponding engine version and click Update. Unreal engine upgrade

Now that the unreal engine is up to date, we will proceed to update Windows.

1. Press Windows + S, scribe “to update” in the dialog and open the update result when you return it.

2. Now, click the Check for updates button. Now, Windows will automatically start checking the servers online for updates available to install. Windows update

Be patient and let the process complete. Once the process is complete, if requested, restart your computer. After reboot, follow the steps below to update Steam.

1. Launch the Steam client and make sure you have an active internet connection.

2. The client, after checking servers online, will automatically start downloading the latest update. After downloading the update, restart your computer again.

After all modules have been updated, try running the unreal engine and see if the error still persists. If so, follow the steps below.

Solution 2: deshabilite NVIDIA Game Booster (or other functions)

Another thing to try before proceeding is to make sure there are no “gets better” active on NVIDIA GeForce Experience. Although these features can alter your settings and give you additional performance, known to cause a number of problems.

Disabling NVIDIA Features

These functions of “gets better” are mainly features like Game Booster, Battery Optimizer, etc. Abra GeForce Experience (or the corresponding application) and make sure they are completely disabled. You can also temporarily disable the GeForce experience entirely and see if it works. Once you are absolutely sure that the problem is not due to these characteristics, can move on to other solutions.

Solution 3: change preference for dedicated graphics

As usual, people who use Unreal Engine and play their games are known to have their own dedicated graphics installed on their computer. Dedicated graphics are typically added later on top of the Intel Integrated Graphics Module (known as Intel HD or Intel UHD).

However, the fact that there are two graphics modules in a single computer causes various problems, which is not surprising. In this solution, we will navigate to the NVIDIA control panel and, after selecting Unreal Engine, we will make sure it is customized to work with NVIDIA graphics drivers only.

1. Right-click anywhere on the desktop and select NVIDIA Control Panel.

2. Once the control panel is open, click Manage 3D Settings. Now click on Program Settings.

3. Now, you will see a drop-down menu with the list of all programs. Add Unreal Engine and select NVIDIA (dedicated graphics) in the second drop-down menu. Graphics card preference change

4. Save Changes and exit. Restart your computer and try to start the module / game and see if this solves the problem.

Solution 4: disable integrated graphics

Another thing you can try is to completely disable graphics on your computer. This might help if just changing the graphics preference isn't enough to make the problem go away. Please note that this will not affect the performance or functionality of your computer; only now, its dedicated graphics will do all the lifting work, while the integrated ones will be inactive. Make sure you are logged in as an administrator before continuing.

1. Press Windows + R, type »devmgmt.msc» in the dialog box and press Enter.

2. Once in device manager, navigate to Display Adapters and select the

3. Now, right click and select Disable. Disable integrated graphics

For a moment, your screen will probably go blank, but it will reappear. Here, the computer is completely switching to its dedicated graphics. Save changes and exit. Now try starting the unreal engine and see if the problem persists.

Solution 5: disable antivirus and firewall software

Antivirus software keeps you safe by scanning all system files on your computer and also checking for all running processes that seem to consume resources. However, there are numerous cases in which you mark a process “verified” as malware; hence it is called a false positive. This situation occurs with many different games and has been known to disable the game completely or not grant you sufficient permissions to access those resources.. The same goes for antivirus software and unreal engine.

Disable antivirus software

Therefore, you should try to disable your antivirus software. You can read our article on How to disable your antivirus. After disabling the antivirus, restart your computer and try streaming again. If disabling antivirus doesn't work, you can try uninstalling it and see if it works for you. Some of the antivirus programs that caused problems were Avast and AVG. However, you should try disabling any antivirus you have and see if it works.

Solution 6: disable overclocking and SLI technology

Overclocking means that the processor performs short burst counts to give your PC a boost in processing power.. When you do this, the processor temperature rises and when it has reached the limit, return to normal processing. During this time, the processor cools down and, Thus, prepares for another blast when it's cool enough.

SLI technology

Despite the advanced features and utility of overclocking, We received several reports from users saying that disabling overclocking for both the CPU and the graphics card solved the problem.. It seems that the unreal engine is not optimized to work in a fast overclocking environment.

What's more, in addition to disabling graphics overclocking / CPU, we also received reports that disabling SLI also worked for numerous users. SLI is a brand managed by NVIDIA whose main objective is to unite two graphics cards to combine their power. As in the case of normal overclocking, Unreal Engine also has problems when SLI is active. Therefore, you should try disabling it from your computer and see if it works.

Solution 7: update graphics drivers

Graphics drivers are the main modules that enable communication between your graphics hardware and the operating system. (apps or games, etc.). If the graphics drivers themselves are not working properly, you will experience problems with almost all graphics that applications like Unreal Engine require. In this solution, we will uninstall existing graphics drivers and install new ones later.

1. Download and install the DDU (Display driver uninstaller) from its official website.

2. After installing Display Driver Uninstaller (GOD), start your computer in safe mode. You can refer to our article on how to start the computer in safe mode.

3. After starting the DDU, select the first option »Clean and restart«. This will completely uninstall the current drivers from your computer. Clean drivers

4. Now, after uninstall, start your computer normally without safe mode. Press Windows + R, type »devmgmt. msc »in the dialog box and hit Enter. Right-click on any empty space and select »Scan for hardware changes«. The default drivers will be installed. Try starting Screenshot and see if this solves the problem.

   Note: You may need to redo the solution 1 after this step.

5. In most cases, the default drivers won't work for you, so you can install the latest drivers via Windows Update or navigate to the manufacturer's website and download the latest ones.

6. Once the drivers are installed, restart your computer and see if the problem is solved.
