Triton: DirectX 11 driver for QEMU

10 days ago

Triton is a new Windows driver that brings full DirectX 11 support to QEMU virtual machines using Neptune, a Direct3D protocol forwarding layer.
Triton implements the DirectX DDI (Device Driver Interface) correctly instead of replacing system DLLs, ensuring better performance, stability, and compatibility with anti-cheat systems.
The DDI approach converts DDI calls back to DirectX API calls, leveraging Neptune's existing serialization protocol without needing a new transport format.
A major challenge is reconstructing DXBC metadata from bytecode since the DDI only passes raw bytecode, requiring synthesis of metadata for the host renderer.
