NVIDIA has announced the new Portal with RTX DLC, free to all current and future owners of Portal. Portal with RTX will release in November 2022 and will be compatible with any GPU capable of ray tracing. The new free DLC, developed by NVIDIA Lightspeed Studios, reimagines Portals graphics with full ray tracing, new hi-res textures, and new enhanced models. These enhancements improve immersion, graphical realism, and the overall gameplay experience. With the DLC installed, you'll be able to choose when you launch the game whether to play the original Portal or Portal with RTX. If you arent familiar with ray tracing, its a method of graphics rendering that simulates the behavior of light. When playing a ray-tracing capable game on a compatible GPU, lighting, reflections, and optical effects appear much more realistic. With ray tracing, light can even pass through portals.
