Test Chamber 12 | Portal with RTX | Walkthrough, Gameplay, No Commentary, 4K

*Portal with RTX* is a remarkable reimagining of the beloved 2007 puzzle-platformer, *Portal*. Released as free DLC for original owners, it's a visual showcase designed by NVIDIA's Lightspeed Studios to demonstrate the power of RTX technology. While the ingenious core gameplay—navigating Aperture Science, solving physics puzzles with the portal gun, and engaging with GLaDOS—remains untouched, the graphics have undergone a dramatic transformation. Every light source is now fully ray-traced, creating incredibly realistic shadows, reflections, and global illumination that dynamically paint the sterile environments with unparalleled depth. Utilizing RTX Remix, the developers have also introduced high-resolution textures and more detailed models, making the world feel more tangible and physically accurate. NVIDIA's DLSS technology is crucial for maintaining playable frame rates with these demanding visual effects, ensuring a smooth experience for those with compatible hardware. Test Chamber 12 in *Portal with RTX* serves as an exceptional tutorial for the crucial "flinging" mechanic. This level, the thirteenth in the game, retains its original puzzle design: ascending a vertically oriented chamber using momentum and portals. The primary goal is to reach the top platform for a Weighted Storage Cube, then use it to activate a lower button, unlocking the exit. The chamber features a deep pit and tiered ledges. Players must strategically place portals, one at the bottom and another on an upper wall panel, to convert falling momentum into horizontal velocity, propelling them across to higher platforms. The puzzle subtly escalates, requiring precise portal placement on angled surfaces to achieve the correct trajectory for the final fling to acquire the cube, which then needs to be placed on a button on the third level. The true magic of Test Chamber 12 in *Portal with RTX* lies in how the RTX enhancements elevate this familiar challenge. The ray-traced lighting renders the stark white walls and metallic panels with breathtaking accuracy, showcasing complex reflections that shift dynamically. The ethereal glow of the portals now interacts with the environment realistically, bathing the chamber in a tangible light. Global illumination naturally softens and defines the spaces, while volumetric lighting adds atmospheric depth, particularly noticeable in the interplay of light and shadow as the player moves. The Weighted Storage Cube itself benefits from new, high-resolution textures, appearing more substantial and physically present. This visual fidelity makes the act of flinging through the air a more spectacular event, highlighting the stark beauty of Aperture Science in a way never before possible, transforming a classic puzzle into a truly immersive graphical spectacle.
