All games that run on UE4 crash on startup

To quickly tell about your issue, these are the errors Windows 10 are reporting to the game when it crashes:

  • first is reported DXGI_ERROR_DEVICE_REMOVED
  • end then DXGI_ERROR_DEVICE_HUNG which will crash

these errors happens because the graphics card stops responding for a certain period (milliseconds) and to try recover it, Windows 10 disconnects the hardware (this is why it is shown DXGI_ERROR_DEVICE_REMOVED ) and tries to reconnect it again, but the device still does not respond in a timely manner resulting in DXGI_ERROR_DEVICE_HUNG. If those errors are not sent to the application and it insists sending commands to the GPU will result in a BSOD (Blue Screen Of Death).

After looking for several posts in the Internet, several reports some root causes which once handled will bring the system to work properly:

  • not overclocking the CPU, leaving at stock clocks
  • not overclocking the RAM, leaving it at auto (not in OC profile either)
  • not overclocking the GPU, leaving it at stock
  • trying to use other PCIe power connectors from the Power Supply
  • make sure the 8 PIN connectors to the motherboard are well connected
  • trying to use more powerful Power Supply (at least Gold and 80 plus certification)
  • update graphics card BIOS (use a technician to do this or you might end with graphics card unusable)
  • update motherboard BIOS (use a technician to do this or you might end with motherboard unusable)

The issue exists for quite some time, and happens with lots of graphics software, not only games.

Make sure your Windows is set to High Performance:

  • Go to Windows Settings
  • Click on System
  • Click on Power & Sleep
  • at right you will see a link to click “Additional Power Settings”, click on it
  • at the Preferred Plan section, choose High Performance

Also, some graphical applications set the TDLr values to avoid the crash at least, you might see hiccups on the application if it is a game. Use the guide I wrote available here: instructionsTDLR.rtf - Google Drive
