An nameless reader quotes a report from Ars Technica: Native DX9 {hardware} help is formally gone from Intel’s Xe built-in graphics options on twelfth Gen CPUs and A-Collection Arc Alchemist discrete GPUs. To switch it, all DirectX 9 help will probably be transferred to DirectX 12 within the type of emulation. Emulation will run on an open-source conversion layer often called “D3D9On12” from Microsoft. Conversion works by sending 3D DirectX 9 graphics instructions to the D3D9On12 layer as a substitute of the D3D9 graphics driver instantly. As soon as the D3D9On12 layer receives instructions from the D3D9 API, it would convert all instructions into D3D12 API calls. So mainly, D3D9On12 will act as a GPU driver all by itself as a substitute of the particular GPU driver from Intel. Microsoft says this emulation course of has change into a comparatively performant implementation of DirectX 9. Because of this, efficiency must be almost pretty much as good, if not simply pretty much as good, as native DirectX 9 {hardware} help.
