Bottom line: The ray traced release trailer showcases a version of Half-Life with enriched visuals that add a new dimension of depth to the nearly 25-year-old game. Everything is still the same at its core, it just looks a lot better with the mod applied.
The long-awaited unofficial ray tracing mod for Half-Life has landed.
A little over a year ago, modder Sultim "sultim_t" Tsyrendashiev shared a YouTube teaser for a new project that adds real-time, hardware accelerated path tracing to Valve's seminal first-person shooter. The mod, a reengineered version of an earlier effort, promised enhancements like reflections, global illumination, refractions and soft shadows.
sultim_t said a playable build and accompanying source code would be released on GitHub when it is ready. "These things, they take time," the modder cautioned.
Fast-forward a little over a year and sultim_t has delivered.
sultim_t is quickly developing a solid reputation in the modding community. Previous projects include ray tracing mods for Serious Sam , Quake and Doom , and joins official mods like Quake II RTX from Nvidia and Bethesda. Digital Foundry described sultim_t's Quake project as less of a mod and more of a full-on ray tracing remaster.
Everything you need to get up and running with the Half-Life ray tracing mod (minus the game itself) has been uploaded to GitHub , complete with instructions on how to install it and a list of known issues. sultim_t warns that some users might experience incompatibility issues with AMD GPUs and further notes that the Hazard Course is not yet supported.
You'll need a copy of Half-Life , of course. sultim_t recommends the Steam version, which can currently be had for $9.99 via the digital distribution platform.
Half-Life has been the source for several mods and remakes since its debut way back in 1998. Among the best is Black Mesa , a fan-made reimagining of the original that eventually earned Valve's blessing and launched on Steam in 2020. It is priced at $19.99 and has more than 85,000 reviews, of which 95 percent are positive.
