ReactOS Runs Half-Life with Hardware-Accelerated 3D on Bare Metal

ReactOS, a ground-up reimplementation of Windows NT built from clean-room reverse engineering, has successfully executed the Direct3D version of Half-Life with GPU acceleration on physical hardware. The milestone matters because 3D rendering cannot hide compatibility gaps—it demands correct driver behavior, memory management, and interrupt handling that virtual machines abstract away. ReactOS remains alpha-stage, but clearing this bar signals its hardware abstraction layer and driver stack have matured beyond synthetic benchmarks.
