Nvidia announced that they are taking what they learned with Portal with RTX and applying it now to Half-Life 2. Nvidia is calling it Half-Life 2 RTX: An RTX Remix Project. This is a move to add some modern visual technologies to the FPS that came out in 2004.

Nvidia pulled in developers from four of Half-Life 2's best mod teams. Together, under the name of Orbifold Studios, they are using the latest version of RTX Remix to add new tech such to Half-Life 2 such as Physically Based Rendering (PBR), higher detail models, full ray tracing, DLSS 3, Nvidia Reflex, and RTX IO.

As with the Portal projects, almost every asset is being reconstructed in high fidelity, and full ray tracing (otherwise known as path tracing) is being leveraged to bring cutting-edge graphics to Half-Life 2. In Half-Life 2 RTX, average world textures have 8X the pixels, and assets like the suit feature 20X the geometric detail of the original game. You can now see the fabric weavings around the joints of the suit, and the interplay of plastics and metals that compose the chest, leg, and arm pieces.

Every light source bounces around the scene and casts realistic shadows, making Kleiner’s Lab feel like a real place. Orange vats cast light that illuminate dark corners in a vibrant glow, while the liquid inside refracts the entire world through it.

Props are transformed with full ray tracing, like the magnification lens on Kleiner’s desk, which used shaders in 2004 to depict a low resolution reflection of the world. Now, the magnifying glass contains a curved lens that realistically refracts light and bends every reflection, heightening immersion.
Half-Life 2 RTX is considered to be early in development. In fact, the team at Orbifold Studios is looking to bring on some additional team members to help on the project.
