Test Chamber 15 | Portal with RTX | Walkthrough, Gameplay, No Commentary, 4K

*Portal with RTX* is a stunning visual upgrade to the beloved 2007 puzzle-platformer, *Portal*. Developed by NVIDIA's Lightspeed Studios™, this free DLC for existing owners transforms the iconic Aperture Science Laboratories with full ray tracing and DLSS. While the core gameplay of solving physics-based puzzles with the portal gun remains untouched, the graphical overhaul is profound. Every light source is ray-traced, creating incredibly realistic shadows, reflections, and global illumination that interact dynamically with the environment. Light now realistically bounces off surfaces and even travels through portals, adding a new dimension of immersion. This visual leap was achieved using NVIDIA's RTX Remix platform, which allowed for the integration of ray tracing, high-resolution textures, and higher-poly models, making the environments feel more tangible and physically accurate. Test Chamber 15 in *Portal with RTX* presents a significant challenge, beautifully rendered with the new visual technology. This chamber introduces more complex "flinging" mechanics, requiring players to master momentum to clear large gaps and energy fields. The original puzzle, which involves placing a portal on a high wall and another on the floor to build speed through repeated falls and ascents, is now experienced with unprecedented visual realism. The chamber is bathed in the dynamic, ray-traced lighting, making the metallic surfaces gleam with accurate reflections of the portals and the crucial high-energy pellet. This pellet, a key element for activating platforms and progressing, glows brilliantly, its light casting soft, realistic shadows that move dynamically, aiding in tracking its path. The particle fields are rendered with volumetric ray-traced light, appearing more substantial and hazardous. High-resolution textures and enhanced models further detail the environment, making the sterile labs feel more lived-in. The addition of material emancipation grills in advanced versions of the chamber, which erase portals, adds an extra layer of difficulty, demanding even more precise timing and placement of portals, all while being enveloped in the breathtaking visual fidelity that *Portal with RTX* offers.
