Troubleshooting GPU Crashes and D3D Device Issues in Unreal Engine

In the vibrant world of game development, a seamless experience can often hinge on the performance of your graphics hardware. Unfortunately, GPU crashes and D3D device issues can disrupt your creative flow, halting progress and leading to frustrating setbacks. But fear not! This blog will help you troubleshoot these GPU crashes and D3D device errors, equipping you with powerful solutions to keep your projects running smoothly and your artistic vision intact.

GPU Crashes and D3D Device Issues refer to problems that can occur with the graphics processing unit (GPU) and the Direct3D (D3D) interface, which is a key component of DirectX used for rendering graphics in applications like Unreal Engine and other game development environments.

In the latest version of Unreal Engine 5 (UE 5.1.1), some users have reported issues of crashing or displaying errors that D3D device has been removed. The error interface will look like the image shown below – ‘GPU crashed or D3D device removed. Use -d3ddebug to enable the D3D debug device. Check the log for GPU state information’. Let’s check the image following:

GPU Overheating and Overload

One of the most common reasons for Unreal Engine crashing is GPU overheating. When rendering complex scenes, compiling shaders, or simulating physics, Unreal can push the GPU to its limit. If your GPU doesn’t have adequate cooling or is operating in a poorly ventilated environment, it may overheat. This causes the hardware to throttle performance or shut down completely, resulting in crashes or a “device removed” error from Direct3D (D3D).

Out of GPU drivers

Another frequent culprit is outdated or corrupted GPU drivers. Unreal Engine relies heavily on the latest DirectX and GPU APIs. If your drivers are outdated, or if recent updates introduced bugs, it can result in the GPU crashing or being removed by Windows.

TDR( Timeout Detection and Recovery Errors)

Windows includes a system called TDR (Timeout Detection and Recovery), which checks if the GPU is unresponsive. If Unreal Engine loads the GPU with a heavy task that doesn’t complete in time (typically 2 seconds), Windows assumes the GPU has crashed and resets it — which in turn causes Unreal to crash.

Corrupted Engine or Project Files

Sometimes, the issue lies within corrupted cache files, shader data, or engine configurations. Unreal stores temporary and compiled data in folders such as DerivedDataCache, Intermediate, and Saved. Over time, these files can become corrupted, especially if the engine or system was interrupted during compilation. If only one project is crashing, try clearing these folders and restarting the engine. You can also regenerate Visual Studio project files if you’re working with C++.

Update the latest driver

Updating your graphics drivers is an important step to ensure that your GPU operates optimally, especially for software like Unreal Engine.

You should visit the NVIDIA website and download GeForce Experience if you haven’t installed it. This software automatically checks for driver updates and allows for easy installation. After the installation is complete, it’s often necessary to restart your computer for the changes to take effect.

You can check the driver version in the Device Manager to confirm that the update was successful by right-clicking on your graphics card under Display adapters and selecting Properties > Driver tab.

Change or add values in Registry Editor

You need to add two registry keys to your graphics drivers. Follow these steps to add the registry keys.

• Type ‘run’ into the Windows operating system search bar. Open the Run application.

After opening the Register editor, you can follow all steps via the instruction link How to change TDR.

Then you should Restart the remote server and connect to it to use normally.

Adjust Unreal Engine Settings( Switch from DX12 to DX11)

To switch to DirectX 11 in Unreal Engine, you can modify the projects or use launch arguments. The primary method involves editing the DefaultEngine.ini file to set the DefaultGraphicsRHI to DefaultGraphicsRHI_DX11. Alternatively, you can use the -dx11 launch argument when starting the editor or the game build. 

Consider Windows Issues

• System Updates: Ensure Windows is fully updated. OS updates may include important fixes that resolve compatibility issues with Unreal Engine and graphical performance improvements.
• Compatibility Settings: Running Unreal Engine with compatibility settings for an earlier version of Windows may help. Right-click on the Unreal Engine executable, go to Properties > Compatibility, and try settings like “Run this program in compatibility mode for” a previous version of Windows.
• Disable Hardware Scheduling: In Windows 11, disabling hardware-accelerated GPU scheduling may help.

Lower Resolution

In Unreal Engine, one of the way of troubleshooting GPU crashes and D3D device issues in Unreal Engine is by lowering the rendering resolution. High-resolution rendering puts significant stress on the GPU, especially in complex scenes with detailed assets and effects.

By reducing the screen resolution and adjusting scalability settings such as texture and effects quality, developers can reduce the GPU workload. This helps identify whether the crashes are caused by excessive GPU strain. If the engine becomes stable at lower settings, it’s a clear sign the hardware is being pushed too hard or is encountering thermal or power issues. This simple adjustment is a crucial first step before diving into deeper troubleshooting.

In conclusion, effectively troubleshooting GPU crashes and Direct3D device issues in Unreal Engine requires a systematic approach. Start by ensuring your drivers and Unreal Engine are up to date, then check system compatibility and performance settings. Use the built-in profiling tools to diagnose performance bottlenecks, and examine log files for specific error messages. Implementing hardware checks, optimizing resource management, and considering the use of validation layers can also aid in identifying and resolving these issues. By following these steps, you can enhance stability and improve the overall performance of your Unreal Engine projects.
