At this year’s Game Developers Conference (GDC), NVIDIA announced that Portal RTX will support DLSS 3.5 technology. This marks a significant upgrade for the classic sci-fi puzzle game. Originally launched by Valve in 2007 as part of the Orange Box collection alongside Half-Life 2 and Team Fortress 2, Portal was praised for its unique humor and spatial mechanics, allowing players to use a portal gun to create interconnected portals on walls, floors, and ceilings, navigating through Aperture Science’s test chambers and defying physics.
In 2022, NVIDIA remastered the game with full ray tracing and RTX series graphics cards, introducing Portal RTX. Now, with the addition of DLSS 3.5, players can leverage AI-driven ray reconstruction to enhance the realism and responsiveness of dynamic lighting effects from panoramic ray tracing. The introduction of NVIDIA RTX IO also speeds up texture loading and reduces game file size. This update not only breathes new life into Portal RTX but underscores the game’s enduring appeal and creativity as a sci-fi puzzle title.
Panoramic Ray Tracing Effects, RTX Remix Remaster
In the original Portal RTX, the game adopted NVIDIA’s panoramic ray tracing technology, also known as path tracing, aiming to create an immersive gaming world. This technology accurately simulates real-world light properties, bringing realistic lighting, shadows, reflections, and refractions to the game’s surfaces and objects. Every element, including floors and walls, has been redesigned to showcase more authentic material details like reflective glass and glossy metals. These enhancements not only make the levels and effects more intricate and dynamic but also allow players to experience realistic light changes, greatly enhancing the game’s sense of realism and immersion.
The game’s developers, using the RTX Remix tool, have undertaken a comprehensive remastering process, meticulously adjusting every pixel to ensure floors, walls, and various objects display more realistic textures and reflection effects. This new technology enables a smarter and more detailed global illumination approach and other ray-tracing effects. Additionally, physically-based rendering adds authenticity to in-game objects, with details like scratches, wear, and rivets clearly visible while maintaining the clinical and minimalist aesthetic of the portal laboratories, ensuring players can easily identify interactive surfaces and portal placement. This remaster not only pays homage to the original but also demonstrates the potential of the RTX Remix mode, an automated tool nearly as advanced as the game’s own portal gun, combining AI, hardware, and software to add ray tracing capabilities to any game.
NVIDIA DLSS 3.5: Perfect Fusion of Image Quality and Performance
With the support for NVIDIA DLSS 3.5 in Portal RTX, the AI-driven ray reconstruction technology employs a new model, replacing traditional denoisers to boost ray-traced image quality for all GeForce RTX GPUs. DLSS 3.5 delivers even more significant visual improvements compared to previous versions, with performance enhancements expected to continue as deep learning progresses. Not only does DLSS accelerate the updating of lighting effects, but it also preserves fine details in the game’s visuals, providing players with a more authentic and breathtaking experience.
By leveraging AI-driven ray reconstruction, the game’s realism and responsiveness are further heightened. DLSS 3.5 not only improves image quality but also allows for higher frame rates without sacrificing performance, delivering smoother and more nuanced gameplay. With DLSS 3.5 and ray reconstruction activated, ZOTAC GeForce RTX 40 series graphics cards offer impressive performance boosts, enabling gamers to enjoy the game at high resolutions without compromise.
NVIDIA RTX IO Boosts Loading Speed, New Storage Cube and Companion Cube
The latest version of the game also introduces NVIDIA RTX IO. This revolutionary technology transforms game loading and asset decompression, utilizing GPU decompression to significantly speed up game loading times and reduce CPU utilization. In Portal RTX, NVIDIA RTX IO can shorten texture load times by up to five times and shrink the game’s disk footprint by 37%. This translates to a smoother, faster gaming experience, allowing players to dive into the game world more quickly and enjoy its offerings to the fullest.
Alongside technical upgrades, the update brings new storage cubes and companion cubes to Portal RTX, enriching the player’s journey through the game world and offering a more diverse gameplay experience. Leveraging Remix technology, players can utilize various alternative models to enhance the game’s lighting effects, making the panoramic ray tracing shine. By creating reward cubes, players can actively participate in the game’s creation, adding to the richness of the game world.
Review
In summary, Portal RTX is a must-play masterpiece. Its unique gameplay mechanics, clever puzzles, and humorous elements combine to provide an extraordinary mix of fun and challenge. The addition of DLSS 3.5 further elevates the gaming experience, showcasing the remarkable advancements in technology. Thanks to NVIDIA’s multiple technologies, the game offers unparalleled immersion and visual fidelity. For puzzle game enthusiasts, this game is definitely worth a try!
Actual Gameplay Testing
The following section presents the results of in-game testing for Portal RTX. To assess the game’s performance on actual hardware, two graphics cards from ZOTAC were selected – the ZOTAC GeForce RTX 4070 SUPER Arctic and the ZOTAC GeForce RTX 4080 SUPER AMP Extreme. Representing ZOTAC’s 2K and 4K offerings, these cards boast excellent performance and striking designs, providing a clear demonstration of performance. Testing was conducted at maximum graphics settings across 1080P, 2K, and 4K resolutions, with DLSS 3.5 enabled and disabled to record frame rate variations. Real-time game screenshots will also be provided for visual comparison of image quality.
