An nameless reader quotes a report from Ars Technica: Native DX9 {hardware} assist is formally gone from Intel’s Xe built-in graphics options on twelfth Gen CPUs and A-Collection Arc Alchemist discrete GPUs. To interchange it, all DirectX 9 assist might be transferred to DirectX 12 within the type of emulation. Emulation will run on an open-source conversion layer often known as “D3D9On12” from Microsoft. Conversion works by sending 3D DirectX 9 graphics instructions to the D3D9On12 layer as an alternative of the D3D9 graphics driver straight. 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 an alternative of the particular GPU driver from Intel. Microsoft says this emulation course of has turn out to be a comparatively performant implementation of DirectX 9. Consequently, efficiency ought to be practically nearly as good, if not simply nearly as good, as native DirectX 9 {hardware} assist.
