NVIDIA has just introduced its new DLSS 3.5 with Ray Reconstruction technology, which actually works on all GeForce RTX series GPUs (so, RTX 20, RTX 30, and RTX 40 series GPUs) and will be launching later this year in select games. NVIDIA showed off DLSS 3.5 in a small comparison running Cyberpunk 2077: Phantom Liberty, which you can check out below. 

Where the new DLSS 3.5 upgrade is new is that it pushes heavily into the Ray (Tracing) Reconstruction (RR) which improves visual fidelity and performance up and above the already impressive DLSS 3. NVIDIA says its new Ray Reconstruction has been trained on 5x more data than what's pumped into DLSS 3, while DLSS 3.5 has also been trained to incorporate additional game and software engine data, recognises multiple ray-traced effects, and can tell the difference between GOOD and BAD temporal and spatial pixels, which keeps high-frequency data for upscaling.

NVIDIA uses denoisers to take away essential data needed for upscaling, which means loss of colour data during denoising and upscaling. Normal methods mean we could have inaccurate lighting effects that are due to a build-up of pixels from previous frames, which normally results in gamers experiencing ghosting.

Denoisers also contribute to subpar global illumination and lower-quality reflections, because there's not enough data for interpolation. But... with DLSS 3.5 and its new Ray Reconstruction, that is a problem of the past.

Jakub Knapik, VP of Art, Global Art Director of CD PROJECT RED, the developers of Cyberpunk 2077, said: "Thanks to DLSS 3.5’s smart technology, fuelled by AI rendering power, you can experience Cyberpunk 2077: Phantom Liberty’s newest location Dogtown at its very best — with sharper images, more accurate lighting, and the highest frame rates possible".
