An improved, open-source version of the X-Ray Engine used in the S.T.A.L.K.E.R. game series, featuring bug fixes, performance boosts, and cross-platform support.
OpenXRay is an open-source, improved version of the X-Ray Engine, the game engine used in the S.T.A.L.K.E.R. series. It fixes original engine bugs, boosts performance, adds 64-bit and cross-platform support, and serves as a modern platform for modders and players. The project is a community effort to enhance and preserve the classic S.T.A.L.K.E.R. experience.
S.T.A.L.K.E.R. players seeking a more stable and performant experience, and modders looking for an extensible, modernized engine to build upon. It's also for developers interested in game engine architecture and open-source game preservation.
Developers choose OpenXRay because it's the only open-source, actively maintained version of the X-Ray Engine that stays true to the original games while offering significant improvements. It provides a drop-in replacement with better performance, cross-platform support, and a strong foundation for modding, all driven by a passionate community.

Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Supports 64-bit systems and runs on Windows, Linux, macOS, *BSDs, and exotic architectures like ARM and PPC64LE, enabling modern hardware utilization and broader accessibility.
Delivers better FPS, optimizes engine performance, and fixes long-standing original X-Ray bugs, improving stability and gameplay as highlighted in the README's main differences.
Introduces new features for modmakers, including a frame/render graph, expanded scripting, and a new game SDK, providing a solid foundation for advanced mods.
Works with Call of Pripyat, Clear Sky, and Call of Chernobyl, with planned Shadow of Chernobyl support, making it versatile for the S.T.A.L.K.E.R. series.
Shadow of Chernobyl is not supported yet, and Clear Sky has minor bugs, limiting immediate compatibility for all S.T.A.L.K.E.R. titles as noted in the README.
Requires building from source with separate wiki instructions for different platforms, which can be challenging for non-developers or those seeking plug-and-play ease.
Needs original game files to run, so it's not a standalone engine, which restricts use to owners of the base games and complicates new project creation.
As a fan-made project without official GSC backing, it may have slower updates, potential legal ambiguities, and relies on volunteer support for maintenance.
