Test Chamber 17 | Portal with RTX | Walkthrough, Gameplay, No Commentary, 4K

*Portal with RTX* is a remarkable update to the beloved 2007 puzzle game *Portal*, released in December 2022 as a free download for original game owners on Steam. Developed by NVIDIA's Lightspeed Studios, this version is a stunning technical demonstration, leveraging NVIDIA's RTX technology to implement full ray tracing and Deep Learning Super Sampling (DLSS). While the core gameplay and narrative of navigating Aperture Science and outsmarting GLaDOS remain intact, the visual transformation is profound. Every light source is ray-traced, producing incredibly realistic shadows, reflections, and global illumination that dynamically interacts with the environment, even passing through portals. This fidelity is achieved using NVIDIA's RTX Remix platform, with new high-resolution textures and higher-poly models adding a tangible quality to the sterile world. DLSS is crucial for maintaining performance with these demanding effects, with DLSS 3 specifically enhancing it for RTX 40 series cards. Though visually impressive, the demanding hardware requirements and the altered aesthetic have sparked some debate among players. Test Chamber 17 in *Portal with RTX* transcends its original design, becoming a visually breathtaking and emotionally resonant experience. This chamber, famous for introducing the Weighted Companion Cube, is profoundly impacted by the full ray tracing and physically-based materials. The sterile test chamber now gleams with realistic lighting, casting soft, dynamic shadows that make the cube and the player feel palpably present. As GLaDOS guides the player through puzzles involving the cube – using it as a platform or to deflect dangerous energy pellets – the ray-traced reflections on the metallic surfaces and the vibrant glow of the pellets themselves create an immersive spectacle. The high-energy pellets now act as mobile light sources, their ricochets painting the environment with transient illumination, enhancing puzzle-solving clarity. The chamber's eventual climax, the "euthanasia" of the Companion Cube, is made all the more impactful. The incinerator's fiery glow, rendered with dramatic, flickering light and detailed textures, casts a menacing hue over the scene. The final lowering of the cube into the flames is a visually stunning metaphor, amplified by the dynamic interplay of light and shadow, making this iconic moment in gaming more poignant and unforgettable in *Portal with RTX*.
