How to launch game on DirectX 10?

Hello everyone! I’m making a very well-optimized game for weak PCs, and it’s already doing well, but I want to know if it’s possible to run the game in d3d 10 on version 4.27. I’ve seen it running on mobile Opengl, so I think it’s possible to run it in d3d, right?
Thank you in advance

Hello @_2287 ,
I did a bit of research and from what I saw, Unreal Engine 4.27 doesn’t offer official support for DirectX 10. While Unreal Engine 3 had limited support for D3D10, this was removed in Unreal Engine 4 due to the technical limitations of the API. Currently, Unreal Engine 4.27 requires at least DirectX 11 for most desktop platforms.

You might have seen your game running with OpenGL because that API is still supported in certain contexts, especially on mobile devices or low-end configurations that don’t require advanced rendering features. However, in the case of DirectX 10, there is no backend available in UE 4.27 to support it directly, so it’s not possible to force its use.

Hope it helps!

This is not my game working( this is a bad translator, but thanks for the answer, do you know how to run the game in opengl mode on windows?
