Greeting:

I need to unreal5 with DirectX12 + Shader Model 6 running on Tencent cloudy rendering machine(VM).

I use Unreal 5.03(5.02 and 5.1 are the same) to build.
With DirectX12 + Shader Model 5(SM 5), it runs well.
With DirectX12 + Shader Model6(SM 6) , it can not be opened,
says:

Op: windows server 2019 datacenter 64
Graphic Card: **Tesla T4 (tencent cloudy rendringCVM)
Graphic Driver: 511.65 likely2022-3 direct12 feature is 12_1

Why this unreal build(dx12+sm6) can not be under on this VM sets.

DirectX 12_2? dx ultimate? need Nvidia driver version > 511?
OS >= win10( windows server 2019 is not OK )?
Or Tesla T4?

Windows Server 2019 is not recommended or supported for UE5. We recommend upgrading to Windows Server 2022. You can see this post for more details.
