Even though applications run on the CPU, many modern-day applications require a lot of GPU support. These apps generate a list of rendering instructions (i.e. the ...

D3D is introducing D3D9on12 with resource interop APIs and adding similar resource interop APIs to D3D11on12.  With this new support, callers can now retrieve the underlying D3D12 resource from the D3D11 or D3D9 resource object even when the resource was created with D3D11 or D3D9 API.   The new D3D9On12 API can be found in the insider SDK...
