Although they are rather dated libraries, DirectX 9, dating back to 2002, can be useful for some software and retrogames of a certain historical period. Apparently, Intel has decided to eliminate native support for these APIs via hardware, replacing it with an emulation via the latest DirectX 12. This system will
take advantage of the open source conversion layer known as “D3D9On12“, made by
Microsoft, which sends the DX9 3D graphics commands to the D3D9On12 layer instead of the D3D9 graphics driver, which subsequently converts them into D3D12 calls. According to statements from the Redmond company, this solution is expected to offer nearly equivalent performance to running through native DirectX 9 hardware support.
Implementing this system should allow Intel to allocate more resources for improvement support for DirectX 11, which at the moment needs more optimizations (at least according to the tests published on the net). Given the efficiency of the Microsoft solution, it is by no means excluded that the other major graphics card manufacturers, such as AMD and NVIDIA, will also decide to adopt the same strategy in the future. However, it should be remembered that this is emulation, so an increase in CPU consumption for the various conversion operations is expected, not to mention that you may have some problems with older games.
