开发团队已将RADV（Mesa开源Vulkan驱动）从Linux移植到Windows，使AMD GPU用户能够使用开源Vulkan实现，而不必依赖专有驱动程序。[1]该项目基于Faith Ekstrand在XDC 2024大会上的前期研究，通过反向工程WDDM2接口实现GPU命令提交功能。[1]项目已成功运行《Counter-Strike 2》游戏，玩家可通过-vulkan参数切换渲染器。[1]Valve赞助了此阶段工作。[1]
该移植版本支持稀疏绑定、细分和任务着色器、动态GPU属性查询等多项功能。[1]然而，开发过程中面临多重技术障碍，包括不同GPU代数间的架构差异、MSVC编译器兼容性问题，以及opaque二进制数据结构的处理。[1]开发团队指出，要实现生产级的稳定性和零复制交换性能（可能带来3倍性能提升），需要AMD或微软的直接参与。[1]
Developers have successfully ported RADV, Mesa's open-source Vulkan driver, from Linux to Windows, enabling AMD GPU users to access an open-source Vulkan implementation as an alternative to proprietary drivers [1]. The project builds on preliminary research presented by Faith Ekstrand at XDC 2024, which identified the WDDM2 interface as a viable foundation for third-party drivers [1]. Through reverse engineering of the private WDDM2 interface using the wddm2-pdd-re tool, the team has achieved GPU command submission and demonstrated the driver's capability by successfully running Counter-Strike 2 with the -vulkan parameter to switch renderers [1].
The RADV Windows port implements several advanced GPU features including sparse binding, tessellation and task shaders, and dynamic GPU property queries [1]. However, the project faces significant technical hurdles, including architectural differences across GPU generations, Microsoft Visual C++ compiler compatibility issues, and challenges with opaque binary data structures [1]. According to the developers, production-level stability and zero-copy swap chain performance—which could potentially deliver a threefold performance improvement—would require direct involvement from AMD or Microsoft [1]. Valve has sponsored this phase of development [1].
