PC Drivers & Software

Hello Community,

using the hardware and drivers mentioned in the subject, I am investigating the DirectX-Graphics-Samples DD12 Mesh Shaders. The first example, D3D12MeshletRender, fails with an exception, the required shader model is 6.5, but 6.4 is being reported. Techpowerup informs me that my GPU is supposed to be shader model 6.5, is that wrong?

I cannot find information about the shader model or DirectX Version in the Driver Software (System Tab) Hardware or Software & Driver Details, which one is it supposed to be?

Edit: DxDiag reports max Feature Level 12_1. Shouldn't it be 12_2 / DirectX 12 Ultimate ?

WDDM 2.6, shader model 6.4 older OS version, Windows 2004 and newer WDDM 2.7 shader model 6.5.

I believe ultimate is dev pack sdk add on ?, not actually a current feature level.

Thanks for clarifying, I assume you mean shader model 6.4 and 6.5 respectively. Guessed that it won't be an AMD (driver) issue, but have not looked into WDDM dependency so far.

Regarding DX12 Ultimate, I think that is the marketing name for feature level 12_2, seems to be one and the same at least according to wiki.

oops, typos fixed, thanks.
