During Gamescom 2023, Nvidia took the stage to introduce the latest evolution of their Deep Learning Super Sampling (DLSS) technology. DLSS, initially launched alongside real-time ray-tracing in games with the Turing-based RTX 20 Series, has undergone significant advancements over the years, encompassing two new GPU generations and the recent DLSS 3 iteration accompanying the RTX 40 Series graphics cards. Today, we delve into the fresh enhancements brought by Nvidia’s DLSS 3.5 update.
DLSS 3.5 Elevates Ray-Traced Visuals
Nvidia’s DLSS technology harnesses the capabilities of artificial intelligence to enhance image quality. With the earlier DLSS 3 update, the company introduced Frame Generation, which effectively doubles FPS, half of which is generated through AI. The introduction of DLSS 3.5 marks a significant step forward. This update introduces a novel feature known as Ray Reconstruction, employing a new AI network trained on supercomputers. Its purpose is to generate “higher-quality pixels in between the sampled rays.”
In contrast to prior methods employing traditional denoisers with manual optimizations, this Ray Reconstruction technique leverages AI in a notably superior manner, resulting in visibly improved image quality. In 2022, real-time denoisers were showcased, enabling developers to achieve impressive in-game visuals with a limited ray budget per pixel.
Ray Reconstruction promises to outshine its predecessor technique. Its impact will be witnessed in new games supporting DLSS 3.5. Furthermore, applications such as D5 Render, Chaos Vantage, and Nvidia’s Omniverse platform, catering to real-time 3D creation, will integrate Ray Reconstruction to enrich image quality. The following games, set for release in the latter half of 2023, will support DLSS 3.5 alongside ray-tracing and Nvidia Reflex:
- Cyberpunk 2077 and the Phantom Liberty Expansion
- Alan Wake 2
- Portal with RTX
Nvidia also revealed their plans for an RTX Remix project for Valve’s acclaimed Half-Life 2. This upcoming mod is set to support comprehensive ray-tracing, DLSS 3, and Nvidia technologies like Reflex, enhancing responsiveness for a more immersive experience.
While DLSS 3.5 is still fresh on the scene and supported by a handful of games, the growing adoption of DLSS 3 (even seeing an unofficial DLSS 3 mod for the AMD-partnered Starfield game) with over 35 games supported so far bodes well for the swift integration of DLSS 3.5.
Anticipation builds for the hands-on testing of DLSS 3.5 with forthcoming graphics drivers and upcoming game titles. Are you excited about the evolution of Nvidia’s DLSS technology? Have the new features left an impression on you? Share your thoughts in the comments below.
