The Xe integrated graphics and Arc Alchemist discrete graphics on Intel’s 12th generation CPUs drop the hardware’s native support for DX9 and will instead support DX9 in an emulated form via DirectX 12 . The simulation will run on Microsoft’s D3D9On12 open source translation layer. It works by sending 3D DirectX 9 graphics commands to the D3D9On12 layer instead of the D3D9 graphics driver. The D3D9On12 layer receives D3D9 API commands and converts them into D3D12 API calls. Microsoft says D3D9On12 emulation performance is comparable to native DirectX 9 hardware support.
