Gaming Gets Boost with Nvidia DLSS 3.5 AI Neural Rendering

This fall, gamers will be able to enjoy more realistic play thanks to the latest Nvidia AI neural rendering techniques in DLSS 3.5 with Ray Reconstruction. Unlike the boost Nvidia provided with DLSS 3’s Frame Generation add-on, DLSS 3.5 boosts ray tracing across the RTX GPU lineup. Nvidia’s new DLSS 3.5 release isn’t only for gamers. Ray Reconstruction is also coming to third-party 3D creator tools like Chaos Vantage and D5 Render as well as the Nvidia Omniverse line of products, providing more accurate previews, among other advantages.

Nvidia shared the news at Gamescom, where the AI-powered graphical upgrade was announced as coming this fall in ray-traced titles such as “Cyberpunk 2077: Phantom Liberty,” “Alan Wake 2” and the remixed puzzle game “Portal with RTX.”

DLSS 3 will be incorporated into high profile fall releases like “Call of Duty: Modern Warfare III,” “Payday 3” and the latest from “Fortnite,” Nvidia notes in a blog post.

“Nvidia is primarily targeting DLSS 3.5 at games that offer path tracing, often known as full ray tracing, as opposed to titles that use ray tracing just for select elements like shadows or reflections,” reports The Verge.

The current DLSS iteration uses hand-tuned denoisers to propagate missing pixels with every lighting pass in a ray-traced scene. The result can be loss of color and lighting accuracy and occasional ghosting. Nvidia is attempting to correct this by using an AI-powered network that the company says generates higher-quality pixels. DLSS 3.5 is trained on five times as much data as its predecessor.

The result is not dissimilar to “Nvidia’s original pitch for DLSS  — making low-res textures look better thanks to AI,” Engadget writes, adding that in images it saw at Gamescom, “Ray Reconstruction appears to deliver sharper reflections and textures in supported titles.”

As for professional creators, Nvidia says real-time 3D applications that use DLSS 3.5 will generate improved image quality previews, saving the trouble of waiting “minutes or hours for the final render.”

“While DLSS 3.5 will benefit regular ray-traced games in image quality and performance, Nvidia says you’ll get a greater performance benefit with path-traced content,” The Verge reports, noting that “more intensive ray-tracing games like ‘Cyberpunk 2077’ and ‘Alan Wake 2’ will benefit the most from DLSS 3.5 both in terms of overall image quality and performance.”

At Gamescom, Nvidia also announced that Xbox Game Pass titles are coming to the GeForce NOW cloud-gaming service, with server upgrades now underway on the platform. The company is also enabling AI to “add emotion to non-playable characters (NPCs)” with NeMo SteerLM for the compoany’s Avatar Cloud Engine and a host of other news detailed on the blog.

Highlights include a community-made RTX Remix of “Half-Life 2,” as reported by Ars Technica.
