Test Chamber 13 | Portal with RTX | Walkthrough, Gameplay, No Commentary, 4K

*Portal with RTX* is a stunning reimagining of the beloved 2007 puzzle-platformer, *Portal*, brought to life by NVIDIA's Lightspeed Studios. Released as a free DLC for original game owners, this version prioritizes showcasing the transformative power of full ray tracing and Deep Learning Super Sampling (DLSS). While the core gameplay remains faithfully intact—navigating Aperture Science Laboratories, solving puzzles with the iconic portal gun, and dealing with the sardonic AI GLaDOS—the visual experience is dramatically elevated. Every light source is now ray-traced, creating incredibly realistic shadows, reflections, and global illumination that dynamically alter the environment. Light realistically bounces off surfaces and even passes through portals, adding a profound new layer of visual depth and immersion. Test Chamber 13 in *Portal with RTX* exemplifies this graphical leap beautifully. While the fundamental puzzle of using Weighted Storage Cubes, buttons, and a high-energy pellet to progress remains, the visual presentation is entirely transformed. The original's clean, flat aesthetic gives way to a chamber imbued with tangible realism. Ray-traced lighting casts soft, accurate shadows, and global illumination ensures that light diffuses naturally, creating a palpable sense of atmosphere. The materials of the chamber itself are now incredibly detailed, with metal panels gleaming and concrete diffusing light realistically, making the environment feel more tactile. Even the scorch marks from the energy pellet appear as physically altered surfaces, offering more intuitive clues. The high-energy pellet itself becomes a dynamic light source, casting vibrant, pulsating light that interacts realistically with its surroundings, and crucially, light now genuinely travels through the portals, a significant visual enhancement. The objects within the chamber, like the cubes and buttons, are now high-poly models with intricate details, further enhancing their physical presence. This upgraded Test Chamber 13, while retaining its ingenious puzzle design, offers an overwhelmingly immersive and visually engaging experience, showcasing the true potential of modern rendering techniques on a classic.
