Portal 2 custom valve intro8/16/2023 The original Portal used point lights exclusively. In Portal with RTX, the test facility’s lights get an upgrade, too. With full ray tracing, light can pass through portals, too, even from the moving High Energy Pellets, causing shadows, reflections and lighting to shift in step. Portal’s unique selling point is of course the ability to take anything through a portal, and see through them, something that hadn’t been done before its release. There are plenty of others, too, enriching each test chamber in ways developers could only dream of back in 2007. Now, thick captivating beams of light pierce through smoke and fog, with light rays realistically scattering, affecting a scene in a realistic manner. Volumetric ray-traced lighting is perhaps the most spectacular, converting the fog effects of old into true, properly simulated volumetrics. Portal with RTX also introduces a number of graphical enhancements that improve ray tracing, immersion, realism, and your overall experience. Portal with RTX and other new ray-traced games and game updates leverage NRD for maximum quality and performance. NVIDIA Real Time Denoisers (NRD) is a new spatio-temporal ray tracing denoising library that assists in denoising ray traced images in real-time, with superior performance and quality. And it also works smarter than previous ray-traced global illumination techniques, improving the efficiency of our ray tracing denoiser.Ī denoiser converts the raw ray-traced output into the beautiful on-screen graphics you experience in Portal with RTX and other ray-traced games. NVIDIA Reservoir Spatio Temporal Importance Resampling Global Illumination (ReSTIR GI) enhances indirect light, enabling it to bathe a scene and illuminate dark corners that are not lit directly. NVIDIA RTX Direct Illumination (RTXDI) enables the addition of countless direct light sources, big and small, each casting light and shadows. Additionally, we’ve also introduced several new ray tracing techniques that further improve quality, while also being more performant. “cutting-edge visual showcase” - AUS GamersĬompared to Quake II RTX and Minecraft with RTX, the full ray tracing introduced by RTX Remix is even more advanced, bouncing light up to four times instead of just once, improving quality, immersion, and the simulation of real-world light.“ Portal’s RTX proves that ray tracing matters.” - Polygon.".transformative experience" - Worth Playing." Portal With RTX is a triumph" - PC Mag.See what press outlets are saying about Portal with RTX: For more details about full ray tracing check out the full tracing section in this article. Illumination, shadows, reflections, refraction, and everything in between are all a result of the fully ray traced world, and their interactions with the upgraded and enhanced assets that have been rebuilt hand in hand with Valve. Compared to our work on Quake II RTX and Minecraft with RTX, light bounces up to four times more, and new technologies are incorporated, making Portal with RTX one of the most advanced showcases for simulated light in gaming. Start thinking with portals, with RTX On.Įach ray of light uses GPU-intensive full ray tracing, also known as path tracing, to accurately model the real-world properties of light, and how that light affects every surface and object. Relive the critically acclaimed and award-winning Portal reimagined with ray tracing, the groundbreaking AI-accelerated performance of NVIDIA DLSS 3, and the best responsiveness with NVIDIA Reflex. Portal remains a timeless classic, with gameplay as fresh, engaging and exciting as it was back in 2007.
