is a reimagined version of Valve’s 2007 classic, released on December 8, 2022 , as a free DLC for all original game owners. Developed by NVIDIA Lightspeed Studios , it serves as a high-end technical showcase for the NVIDIA RTX Remix modding platform. Core Technical Features

This remaster completely overhauls the game's original Source engine visuals with advanced rendering techniques:

Every frame is rendered using path tracing, meaning light bounces realistically off surfaces and passes through portals to illuminate rooms naturally.

The visual fidelity comes with significant hardware demands, making it one of the most GPU-intensive titles at its release: Portal with RTX on Steam

The DLC features hand-crafted, high-resolution textures based on physically-based rendering (PBR) and high-poly models that retain the aesthetic of the original.

Light now realistically scatters through fog and smoke, creating "god rays" and pixel-perfect shadows. Performance and DLSS Support
