Half-Life 2 RTX has no release date. As of October 2026 the only playable part is the free Steam demo from March 18, 2025. It covers Ravenholm and Nova Prospekt and needs Valve's 2004 shooter. Orbifold Studios rebuilds the game's models, materials and lighting for full ray tracing with NVIDIA's RTX Remix.

Four Half-Life mod teams became Orbifold Studios

NVIDIA announced the project on August 22, 2023 as an unofficial, community-made remaster. Orbifold was put together from four mod teams: Half-Life 2: VR, Half-Life 2: Remade Assets, Project 17 and Raising the Bar: Redux. Valve was not part of it.

Two months after the announcement, co-leads Chris Workman and David Driver-Gomm explained the goal to Lambda Generation. "We really want to remaster the experience," Workman said. "We all have this perfect image of Half-Life 2 in our heads from the first time we played it." Driver-Gomm on the trade-offs: "You often have to make a lot of sacrifices to make it happen."

The work splits into art and lighting. The wiki lists the first job as recreating models and materials with physically based properties, then adding level detail in the Hammer editor. Remix handles the light: in Driver-Gomm's words, it "interprets the lights that are already in the scene and then it converts them into path traced lights." The new models are far heavier than Valve's. In the same interview Driver-Gomm put the HEV suit at about 95,000 polygons against the original's 2,800, and a headcrab at 49,668 against 1,690.

The demo was an 80 GB download. Half-Life 2 itself is 6.5 GB.

On March 19, 2025, the day after launch, PCGamesN reported a 58 percent Mixed score. Some of the players complaining about performance had 5000-series NVIDIA cards. Another user in the same article said the demo made the game look "how I remember it looked" in 2004.

What the Half-Life 2 RTX demo covers and how to play it

You need Half-Life 2 in your Steam library first. The Half-Life 2 RTX page describes the project as a free DLC for owners. The base game cost €9.69 on the European store on October 22, 2026. 97 percent of its 91,650 English reviews were positive.

The demo has levels from the chapters "We Don't Go To Ravenholm..." and Nova Prospekt. NVIDIA's Nyle Usmani put the length at around two hours of gameplay. The Steam page carries a content note for violence against humanoid and alien enemies, plus zombies and corpses with detailed gore. Alt+X opens the RTX Remix menu, where you switch between quality presets.

NVIDIA says DLSS 4 with Multi Frame Generation reached 265 frames per second at 4K on an RTX 5090. A Neural Radiance Cache speeds up indirect lighting by up to 15 percent. Father Grigori, the headcrabs and the zombies get subsurface scattering from RTX Skin. RTX Volumetrics draws the smoke, fog and light shafts.

What RTX Remix does under the hood

RTX Remix is NVIDIA's modding platform for DirectX 8 and 9 games, according to its documentation. It has a runtime that runs next to the game and a toolkit for building mods. The runtime swaps in the remastered assets as the game plays and relights each scene with path tracing. The toolkit is the offline editor, with AI texture tools and asset replacement.

Objects that Remix adds are visual only. The original game logic runs underneath, unchanged. Remix came out of beta with the demo.

System requirements and performance

The Steam page lists a minimum of a Core i5-8600 or Ryzen 5 3600, 16 GB of RAM, an RTX 3060 Ti with DLSS on and 50 GB of storage, on 64-bit Windows 10 or 11. The recommended card is an RTX 4070, again with DLSS on.

Above Full HD the demo calls for an RTX 4090, 5080 or 5090. AMD graphics cards are not supported. PC Perspective, in its first look at the demo, said the 3060 Ti would struggle to hold decent frame rates.

On October 22, 2026 the Steam page showed 53 percent positive from 4,669 English reviews, still Mixed, and 50 percent from the 51 reviews of the last 30 days. I think the spec sheet explains most of that: even the minimum card only qualifies with DLSS switched on.

Release date and what changed since the demo

heise online reported in March 2025 that the full game was planned for later that year without an exact date. That year ended without a release, and VGTimes still lists no date in October 2026.

In June 2026, NVIDIA's RTX Remix 1.5 added RTX IO compression, and NVIDIA says Half-Life 2 RTX shrank from 80 GB to 50 GB with it. Portal with RTX went from 25 GB to 17 GB.
