NVIDIA DLSS 3.5 was announced at this year’s GamesCom 2023 opening night and is said to arrive this coming fall. The next iteration appears to have a focus on a new feature called Ray Reconstruction (RR) to provide significantly improved visuals when using ray tracing effects. RR is a type of denoiser and is said to have been trained on five times more data than DLSS 3. According to VideoCardz denoisers often create graphical anomalies due to a lack of data, but also strip away data that is needed for upscaling while also reducing color data.
Per VideoCardz:
“The utilization of denoisers was found to strip away essential data required for upscaling, leading to a loss of color data during denoising and subsequent upscaling. Furthermore, traditional methods may result in inaccurate lighting effects due to the accumulation of pixels from previous frames, often resulting in ghosting.”
“Denoisers also contribute to subpar global illumination and lower-quality reflections, as there isn’t enough data for interpolation. This will not be the case with Ray Reconstruction, which is the primary feature of DLSS 3.5 update.”
How DLSS 3.5 Works
According to slides provided by NVIDIA, Ray Reconstruction performs through four essential steps. RR is first trained to incorporate addition engine and software data, recognize the ray-traced effects, analyze and separate the good and bad temporal and spatial pixels, and then ultimately retain the high-frequency data needed for improved upscaling. Ray Reconstruction can also provide additional FPS in gaming over previous DLSS technology when combined with super-resolution (DLSS 2) and frame generation (DLSS 3).
NVIDIA DLSS 3.5 is set to arrive this fall and will debut in CyberPunk 2077 Phantom Liberty (September 26), Alan Wake II (October 27), and NVDIA’s developer tools, Ominiverse Platform, Chaos Vantage, and D5 Renderer.
