When trying to run my Project in editor using DirectX12 (-DX12 as startup), editor crashes instantly when viewport is visible.

Dx12 support is still fairly new and we are updating as we go forward. Would you mind trying to run -DX12 on 4.14 to see if you still get a crash.

Sure, reported just in case. :slight_smile: Excited to see DX12 running sooner or later. Will test the DX12 on future builds too. I didnt manage to get my Project running yet on 4.14. There was some other issue. Will try on 4.14.1 and later hotfixes soon.
