NVIDIA’s DLSS 3.5: A Game Changer for Ray Tracing

In the ever-evolving realm of graphics technology, NVIDIA is stepping up its game with the introduction of DLSS (Deep Learning Super Sampling) 3.5, an AI-driven algorithm that aims to revolutionize ray tracing. This latest update, part of NVIDIA’s ongoing commitment to enhancing the gaming experience, brings to the table an innovative feature known as Ray (Tracing) Reconstruction (RR).

The Evolution of DLSS

Over the years, DLSS has seen multiple significant iterations: DLSS1 (March 2020) DLSS 2.3 (November 2021) DLSS 3 (October 2022) DLSS 3.1 (January 2023) The focus of the most recent versions has been the enhancement of ray tracing, a technique used for producing images by tracing the path of rays of light as pixels in an image plane.

DLSS 3.5: Ray (Tracing) Reconstruction

The crowning jewel of DLSS 3.5 is the Ray (Tracing) Reconstruction (RR). Traditional denoising techniques often resulted in the loss of essential data required for upscaling, such as color data and accurate lighting effects. This, in turn, sometimes caused problems like ghosting due to pixel accumulation from previous frames. However, the RR feature promises to be a solution to these challenges. Key highlights of the RR include: Trained on five times more data than DLSS 3. Incorporates additional game and software engine data. Can distinguish between good and bad temporal and spatial pixels. Preserves high-frequency data for more accurate upscaling. This new approach is poised to render traditional denoisers obsolete, as the Ray Reconstruction provides enhanced visual clarity and improved global illumination. Traditional issues such as inaccurate lighting effects, subpar reflections, and ghosting are things of the past.

Compatibility and Integration

DLSS 3.5 isn’t just limited to a specific range of GPUs. In fact: Unlike the DLSS 3’s Frame Generation, which was exclusive to the RTX 40-series GPUs, DLSS 3.5 will be available across all RTX-series GPUs, including the RTX 20 series. NVIDIA is targeting games that utilize full ray tracing or path tracing. Some of the titles expected to feature DLSS 3.5 include: Cyberpunk 2077: Phantom Liberty (releasing on September 26th) Alan Wake 2 (launching on October 27th) Portal with RTX Furthermore, creators won’t be left behind. They can expect to see DLSS 3.5 integration in 3D editing apps like Chaos Vantage, D5 Render, and NVIDIA Omniverse. The AI-powered ray reconstruction promises higher-quality and more precise render previews in these applications.

Upcoming Game Supports

Several other major titles are in line to benefit from NVIDIA’s tech: Fortnite is receiving a DLSS 3 update this fall. Call of Duty: Modern Warfare 3 will also feature DLSS 3 and Reflex upon its release on November 10th.

AMD’s Counter

While NVIDIA is making waves with DLSS 3.5, AMD isn’t sitting still. Rumors suggest the imminent launch of FidelityFX Super Resolution 3 (FSR 3) at Gamescom. This latest version of AMD’s upscaling technology is expected to debut alongside Starfield in the coming month.


The world of graphics technology is moving rapidly, with both NVIDIA and AMD pushing boundaries. DLSS 3.5, with its innovative RR feature, looks set to elevate the gaming experience to unprecedented levels. However, only time will reveal the true impact of this technology on the industry.
