Does AIDA64 report GPU use correctly when a native DX12 app is running? See this post for example, regarding DX12 and the Windows 10 Task Manager:

AIDA64 doesn't measure DirectX GPU utilization, but hardware GPU utilization as reported by the GPU itself.  So it doesn't depend on the actual DirectX, OpenGL or Vulkan layer used.

Thanks. AIDA looks like it is reporting correct GPU use with DX12 apps. I just wanted to make sure that the DX12 issue was limited to the  Windows 10 Task Manager.

It is an issue for such apps that report GPU usage through a graphics API layer.  We fortunately measure GPU utilization directly.
