ReactOS has successfully executed Valve's original Half-Life on consumer hardware, marking a significant milestone in open-source software development. This achievement was announced on June 10, 2026, after three decades of effort to reimplement Microsoft Windows. The game was run on a Dell OptiPlex desktop with an Intel Core i5 2400 processor and an NVIDIA GeForce 8400GS graphics card, demonstrating ReactOS's capability to handle real-time 3D applications without compatibility shims. ReactOS operates independently from Microsoft, sharing no code, and can execute a real-time 3D graphics workload natively. It has achieved approximately 90 percent GPU driver compatibility for Windows XP and Server 2003-era hardware through the implementation of the Kernel-Mode Driver Framework and Windows Display Driver Model subsystems. ReactOS is still in alpha stage, with limitations in application support and driver gaps for modern hardware. The project is working towards a new release, version 0.4.16, to enhance user experience.
