UE4 crashes when opening with DX12 shortcut

Hi, I had the same problem for a while now, but found a quick fix for it:

Do you have these or similar programs installed?

  • MSI Afterburner
  • RivaTuner Statistics Server (Comes with Afterburner if not unchecked)

After stopping both processes the error message stopped appearing.
Watch out for RivaTuner Statistics Server as it is automatically restarted if MSI Afterburner is still running.

I hope I could help you with your issue.
