Fix 6. Change Windows Registry

The TDR recovery level settings may also lead to Unreal Engine 4 crashing. TDR is a Windows feature that detects when the GPU is not responding within a certain time frame and attempts to recover it by resetting the GPU driver. If the TDR recovery level is set too low, it can cause Windows to incorrectly interpret UE4's intensive GPU processing as a non-responsive state, leading to crashes.

The Unreal Engine crash fix for such a situation is changing the Windows registry in the following way.

• Open 'Run' by pressing 'Windows' and 'R' key. Type in 'regedit' and hit enter to open Registry Editor.

  

• You'll need to create a backup of the registry entries. Click on 'File' and then on 'Export.' Specify the location where you want to save the backup copy, give the file a name, and click on 'Save.'

  

• Go to Registry Editor again and follow the below path.

  HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\GraphicsDrivers

• Right click on the empty space, go to 'New', select 'QWORD (64-bit) Value' and give the name of the new value as 'TdrDdiDelay.'

  

• Double click it on TdrDdiDelay, change the value to '30' and Base to Decimal, and then click OK to confirm.

  

• Next, create another DWORD and name it TdrLevel. Double-click it and change the Base to Decimal and value to 3.

  
• Click OK and that's done. Now you can exit Registry Editor and restart your computer.

Fix 7. Run Unreal Engine Game in DirectX11 Mode

If you're facing issue of Unreal Engine 4 games crashing on startup when using DirectX 12, a simple solution to this is to run the UE game in DirectX mode. Here's how:

• Launch Steam Client and go to 'Library'.
• Right click on the game and click on 'Properties'.

• Select 'General', scroll down to 'Launch Option', and key in '-dx11' in the given text field.

  
• In the main library, click on 'Play'.
• Select 'Play in DX11 Compatibility Mode' and hit the 'Play' button.

After this the selected game will get refreshed and play in the DirectX 11 mode.

Fix 8. Perform SFC Scan to Repair System Files

If you feel that some corrupt files may be causing this issue, you can perform a SFC scan to repair the system files in the following way.

• Open 'Run' by pressing 'Windows' and 'R' keys together.
• To run the command prompt as an administrator, key in 'cmd' and press 'Enter' key.

• Key in the following command and hit enter.

  sfc /scannow

  

• Once the scanning is done, key in the following commands one by one to run dism.exe.

  dism.exe /online /cleanup-image /scanhealth

  dism.exe /online /cleanup-image /restorehealth

  dism /online /cleanup-image /startcomponentcleanup
