Similar to how Half-Life 2's Gravity Gun innovated new ways to leverage an object in any given situation, Portal allows you to solve physical puzzles and challenges by opening portals to maneuvering objects, and themselves, through space.

Experience Portal reimagined with ray tracing.

Every frame of gameplay is upgraded with stunning full ray tracing, new, hand-crafted hi-res physically based textures, and new, enhanced high-poly models evocative of the originals, all in stunning 4K.

In Portal with RTX, full ray tracing transforms each level, enabling light to bounce and be affected by the scene’s geometry and materials. Every light is ray-traced and casts shadows, global illumination indirect lighting naturally illuminates and darkens rooms, volumetric ray-traced lighting scatters through fog and smoke, and shadows are pixel perfect.

Performance is accelerated with NVIDIA DLSS 3, and system latency is minimized using NVIDIA Reflex. To achieve the stunning new look, Portal with RTX utilizes a suite of demanding graphics techniques that are accelerated by NVIDIA DLSS technology. DLSS 3 allows 40 Series GPU users to get over a 2.8X increase in performance, making the game incredibly smooth and responsive compared to native rendering, while 30 series GPU users will benefit from DLSS 2, bringing the game to a playable experience.

Portal with RTX is compatible with all ray-tracing capable GPUs.

“Updating much-loved games requires a balance of applying new, bleeding-edge techniques, while staying true to the original spirit of the game. The experience NVIDIA’s Lightspeed Studios gained working on RTX versions of renowned games such as Minecraft and Quake II gave Valve the confidence to entrust us to bring modern graphics techniques to their legendary game, and NVIDIA RTX Remix gave us the perfect tool to complete the task,” said head of Lightspeed Studios John Spitzer.

Portal with RTX System Requirements

Portal with RTX’s full ray tracing is incredibly demanding, stressing graphics cards to their limits. But with the help of DLSS 2, owners of the GeForce RTX 3060 will be able to achieve playable frames at 1080p at High settings. For a 60 FPS+ 1080p, High settings experience, we recommend the GeForce RTX 3080, accelerated by DLSS 2.

And to enjoy the ultimate Portal with RTX experience at 4K, with Ultra settings, at over 60 FPS, we recommend the GeForce RTX 4080 with the amazing DLSS 3 enabled.
