Half-Life 2 RTX demo releases March 18 with new mod tools.

NVIDIA has officially announced that a demo of Half-Life 2 RTX will be available on March 18, 2025. This remastered version of Valve’s classic 2004 shooter utilizes NVIDIA’s RTX Remix technology to introduce advanced features such as full ray tracing and DLSS 4 with Multi Frame Generation. The demo offers players a glimpse into the enhanced visuals and performance improvements made possible by these cutting-edge technologies.
Developed by Orbifold Studios, a team of dedicated fans, Half-Life 2 RTX aims to modernize the game’s graphics while preserving its original gameplay. The demo will feature reimagined versions of the Ravenholm and Nova Prospekt levels, showcasing updated textures, models, and lighting effects. Players who own the original Half-Life 2 on Steam can access this demo for free, providing an opportunity to experience the game’s revitalized aesthetics firsthand.
The release of this demo coincides with the official launch of NVIDIA’s RTX Remix modding platform, which has exited its beta phase. RTX Remix empowers modders to enhance classic games with modern visual effects, including ray tracing and AI-driven technologies. Since its beta release, over 30,000 modders have used RTX Remix to modify numerous titles, with more than one million gamers experiencing these enhanced versions.
In addition to ray tracing and DLSS 4, the Half-Life 2 RTX demo incorporates NVIDIA’s RTX Neural Radiance Cache, RTX Skin, and RTX Volumetrics technologies. These advancements contribute to more realistic lighting, character rendering, and atmospheric effects, further immersing players in the game’s environment. The demo serves as a testament to the potential of RTX Remix in transforming the visual fidelity of classic games.
As the gaming community eagerly anticipates the full release of Half-Life 2 RTX, the upcoming demo provides a promising preview of what’s to come.
