Intel has begun testing a significant update for its Windows drivers, Intel Arc Graphics Driver 31.0.101.3959, for GPUs featuring Arc (Alchemist) and Iris (DG1), as well as for integrated GPUs in processors based on the Tiger Lake, Rocket Lake, Alder Lake, and Raptor Lake microarchitectures. The most notable changes in this version focus on enhancing game performance using DirectX 9. It is believed that the optimizations are made possible by utilizing code from the open-source project DXVK, which provides a layer implementing DXGI (DirectX Graphics Infrastructure), Direct3D 9, 10, and 11 through API call translation to Vulkan.
The mention of DXVK appeared in a file listing third-party open-source projects whose code has been used in the driver. Additionally, a video discussing the changes related to DirectX 9 support mentions that this API is implemented through call translation to a more modern graphics API, which is precisely the kind of translation being developed in DXVK. A reference to the hybrid implementation of DirectX 9 in the Intel Arc Graphics Driver is also included in one of Intel's blog posts.
