1. Introducing NVIDIA DLSS 3.5: A Breakthrough in Ray Tracing Technology

NVIDIA DLSS 3.5 is a groundbreaking technology that takes ray tracing to the next level by enhancing the quality of ray-traced images in intensive games and applications. With the introduction of Ray Reconstruction, a new AI model, DLSS 3.5 creates higher quality ray-traced images that are sharper, more accurate, and visually stunning. This innovative technology is powered by the Tensor Cores inside each GeForce RTX GPU, leveraging the AI hardware and software developed by NVIDIA.

DLSS 3.5 builds upon the success of its predecessor, DLSS, which was introduced five years ago and has since undergone continuous learning and improvement. The AI models behind DLSS have been trained with even more data, resulting in better performance and new innovations that further multiply the capabilities of ray tracing. By replacing hand-tuned denoisers with an AI network trained on offline-rendered images, DLSS 3.5 recognizes different ray-traced effects and makes smarter decisions about using temporal and spatial data. This not only improves image quality but also retains high-frequency information for superior-quality upscaling.

2. Understanding Ray Tracing and its Challenges

Ray tracing is a rendering technique used in game engines to create realistic lighting and reflections. It works by shooting rays from the camera’s viewpoint to determine how light interacts with objects in a scene. These rays simulate the behavior of real light, bouncing off surfaces and creating reflections, shadows, and other lighting effects. However, shooting rays for every pixel on the screen is computationally demanding and time-consuming, even for offline renderers that calculate scenes over minutes or hours. To overcome this challenge, ray samples are used instead. These samples fire a handful of rays at various points across the scene to capture a representative sample of the lighting, reflectivity, and shadowing. The output is a noisy image that provides an approximation of how the scene should look when ray-traced.

One of the main challenges in ray tracing is the need to fill in the missing pixels that weren’t directly ray-traced. This is where hand-tuned denoisers come into play. These denoisers use temporal accumulation and spatial interpolation techniques to blend neighboring pixels together and create a smoother image. However, these manual tuning processes can be complex and costly, as each type of ray-traced lighting requires its own denoiser. This not only adds complexity to the development process but also reduces the frame rate in highly ray-traced games where multiple denoisers are used simultaneously. Additionally, hand-tuned denoisers can remove fine details and introduce artifacts or non-uniform lighting effects if not properly calibrated.

3. The Power of NVIDIA DLSS 3.5’s Ray Reconstruction

With the introduction of Ray Reconstruction, NVIDIA DLSS 3.5 takes ray tracing technology to new heights. This AI-powered neural renderer plays a crucial role in improving the quality of ray-traced images in intensive games and applications. By replacing hand-tuned denoisers with an NVIDIA supercomputer-trained AI network, Ray Reconstruction recognizes different ray-traced effects and makes smarter decisions about using temporal and spatial data.

One of the key advantages of Ray Reconstruction is its ability to retain high-frequency information for superior-quality upscaling. By recognizing lighting patterns from training data, such as global illumination or ambient occlusion, Ray Reconstruction recreates these patterns in real-time gameplay. This results in higher-quality pixels between sampled rays, which significantly enhances image quality in ray-traced scenes.

4. Real-Life Examples: DLSS 3.5 in Cyberpunk 2077 and Portal with RTX

Let’s take a closer look at how DLSS 3.5 enhances the visual experience in two popular games: Cyberpunk 2077: Phantom Liberty and Portal with RTX. In Cyberpunk 2077, DLSS 3.5 utilizes Ray Reconstruction to improve lighting, reflections, and overall image quality. With DLSS 3.5 enabled, you’ll notice sharper images, more accurate lighting, and higher frame rates, allowing you to fully immerse yourself in the vibrant world of Night City.

In Portal with RTX, DLSS 3.5 takes the visuals to another level by enhancing the quality of ray-traced effects such as reflections. With DLSS 3.5, you’ll experience stable and accurate reflections, without any blotchy or boiling effects. The AI-powered neural network behind DLSS 3.5 recognizes patterns associated with reflections and generates high-quality pixels while blending neighboring pixels for superior image quality.

5. DLSS 3.5 Beyond Gaming: Enhancing Creative Applications

DLSS 3.5 not only revolutionizes gaming with its advanced ray tracing technology, but it also brings significant benefits to creative applications. By leveraging the power of AI and neural rendering, DLSS 3.5 is able to recognize a wide variety of scenes in creative applications, resulting in high-quality images during the preview process. This is particularly valuable for artists, architects, and designers who rely on real-time rendering capabilities to visualize their ideas and make informed decisions.

An excellent example of an industry-leading app that will integrate DLSS 3.5 is D5 Render. As one of the top apps for architects and designers, D5 Render is constantly pushing the boundaries of real-time rendering. With the integration of DLSS 3.5, D5 Render will be able to deliver even higher-quality images during the preview stage, allowing users to accurately assess lighting, materials, and other visual elements before committing hours to a final render. This collaboration between NVIDIA and D5 Render showcases the potential of DLSS 3.5 in enhancing creative workflows and empowering professionals to create stunning visual experiences.
