DXVK and VKD3D have been translating DirectX 9-12 to Vulkan for a while now, allowing DirectX games and applications to run on hardware and/or operating systems that don’t support DirectX.
Intels ARC GPUs don’t even support DirectX on a hardware level, like it’s just straight up not there. Intels drivers instead just translate it to Vulkan, and their at times insane FPS boosts from driver updates was due to them improving that translation and getting closer to 1:1 performance.
