If Unreal cannot establish a connection with your computer’s D3D device, you will see the error message “Unreal Engine is quitting due to D3D device being lost.” This is a widespread problem, and it can even affect people whose machines seem to be functioning normally.
Method 1: Putting The Latest Patches And Updates into Windows And Steam As Well As Unreal Engine
If either of the aforementioned parts is out of date, it will likely interfere with the other’s functionality. The game will not function correctly if communication is weak. It’s a typical problem that keeps coming up, but most people tend to ignore it.
While Windows and Steam take only a few minutes to update, the process for updating the Unreal engine can take a while. Log in as an administrator and carry out each procedure as described. First, we’ll get Unreal Engine up to date.
Step 1: Simply launch your device, then head to the Library.
Step 2: The Engine version can be seen at the very top of the Library. A + sign will appear next to it if an update is available.
Step 3: It’s easy to install a new engine—just click the “Add versions” button. Get the latest engine version and then select Update.
With the latest version of Unreal Engine installed, we can go on to Windows.
Step 1: In order to access Update, press Windows + S, then type “update” into the search bar.
Step 2: Select the Check for updates button now. Windows will now routinely check Microsoft’s update servers to see if any newer versions are available.
Don’t rush things; wait till they’re done. If requested, restart the computer once the operation is finished. Follow these instructions to update Steam after you’ve restarted.
Step 1: Turn on your internet connection and fire up the Steam client.
Step 2: After confirming that an update is available on the remote servers, the client will initiate the download immediately. Again restart the device when the update has been downloaded.
Method 2: Turning Off NVIDIA’s Game Boost (or Other Functions)
We should also check that NVIDIA’s GeForce Experience isn’t using any of its “improvement” features before continuing. These features may allow you to tweak the settings and gain some extra functionality, but they have a history of triggering a variety of problems.
Most of these ‘improvement’ features, such as Game Booster, Battery Optimizer, etc., are merely utilities. In order to disable these entirely, launch GeForce Experience (or the appropriate programme) and follow the on-screen instructions.
Another option is to temporarily turn off the GeForce Experience to see if it helps. After confirming that these components are not at fault, you can move on to other potential fixes.
Method 3: Alternatives to Shared-Video Memory
Those who are familiar with Unreal Engine and its games typically have high-end graphics hardware installed on their computers. When an Intel processor has an integrated graphics module, a separate graphics card is typically added later (known as Intel HD or Intel UHD).
But it’s not surprising that having two graphics units in a single computer can cause a number of problems. In this workaround, we’ll use NVIDIA’s settings menu to tailor Unreal Engine for use with the company’s graphics drivers.
Step 1: If you right-click the desktop, you may access the NVIDIA settings menu.
Step 2: When the settings menu appears, select Manage 3D Settings. Select Preferences from the menu.
Step 3: A menu including all available apps should now appear. Select NVIDIA (Dedicated graphics) from the second drop-down menu after adding Unreal Engine.
Step 4: Complete your edits and click “Exit” to save and leave. Try opening the module/game again after restarting your computer to see if this helps.
