High GPU usage on using D3D9On12 #90
Description
Hello,
We are facing high GPU usage when we use D3D9On12. For testing we are using Tut06_Meshes tutorial given in DirectX9 SDK (Path: C:\Program Files (x86)\Microsoft DirectX SDK (June 2010)\Samples\C++\Direct3D\Tutorials\Tut06_Meshes).
When we run this sample our GPU usage for this application 2-3 while if i run the same sample enabling device D3D9On12, our GPU usage goes to 10-15 with this sample.
GPU usages difference in our application is up to 25-30% between DirectX9 and D3D9On12.
Below is code snippet showing how we are creating D3D9On12Device.
We followed https://devblogs.microsoft.com/directx/coming-to-directx-12-d3d9on12-and-d3d11on12-resource-interop-apis/ this devblog to convert our Engine from DirectX12 to D3D9On12.
Please help. !!!!!
