UE5.1 DX12 PIE Crash : EXCEPTION_ILLEGAL_INSTRUCTION (Solved)

Thank you for your reply! :slight_smile:

I’ve already switched from DX11 to DX12 (SM6) the same day I upgraded my project from UE5.0 to UE5.1 - and this crash started to happen after I make the switch to UE5.1

I’ve visited the thread you mentioned before posting here, and it seems the problem is either :

  • Not switch to DX12 or
  • MSI afterburner is messing with Unreal Editor

both are not applicable to my case, unfortunately :frowning:

A similar case I found was on UnrealSlacker Discord channel where the person posted the exact same crash report as mine - he was using DX12 with the latest Nvidia driver, however, no solution was given except suggesting he downgrade from DX12 to DX11 to prevent the crash from happening again.
