How to active DirectX 12?

[NightroGames]

Hi, I’m new to unreal Engine.

I have Unreal Engine 4.12.3 and have no Idea on how to go about activating DX12. I found options in what I remember to be in the File tab and only had the options for DX10 and 11. There are noYouTube videos for this and would probably be very useful to a lot of people if there happens to be a YouTuber out there who know how to do this. I found this but am unsure how to go about doing this.

How to enable DirectX 12 on UE4.11

Also, does it matter if you start you started making your game without activating DX12 first or not?

Create a shortcut of UE4Editor.exe and at Target add -dx12 at the end of line (after the “…” -dx12). You can also go to project settings, Target Hardware, Windows and uncheck DX10 and DX11 and it will automatically run on DX12. If this will break your stuff i don’t know, its just info from AnswerHub.

Edit: however, for me currently, DX12 takes 10-20 fps away on my 970GTX.

If you have to ask this question here, then you should not use DX12.

I had the same question and couldn’t find all the comprehensive information bundled at one place.

And so I decided to create this Video Tutorial & Blog Post.
How to activate Real Time Rendering with Unreal Engine (UE4) - DX 12 and Ray Tracing with Nvidia and the RTX Technology.

Please let me know if I forgot something to mention, or if I missed something important I should add.
I hope that will help everyone - super stoked & happy about Epic Games!

Happy Ray Tracing

The shortcut method did not work for me but going into settings did the trick, Thank you

I disagree. With UE4.26 The atmospheric fog is crashing everytime I try and place it in my editor. Supposedly I’m running Vulkan, and it crashes when placing Atmospheric Fog.
