Nvidia has announced its new generation of DLSS Ray Reconstruction technology. The newest iteration of the tech will work alongside the other improvements coming with DLSS 4.5 to offer better image quality in games while making use of ray tracing and path tracing. The company has said that it will make use of a new 2nd generation transformer model to achieve this. It will be coming to all Nvidia GeForce RTX GPUs in August. Check out the video announcing the feature below.
DLSS Ray Reconstruction is a tool that can be used in games to improve visual quality and frame rates without having to rely on hand-trained denoising techniques. The technology makes use of neural rendering and is available on all of Nvidia’s GeForce RTX graphics cards. The latest iteration of the tech has been trained on Nvidia’s own supercomputers and is capable of generating higher-quality pixels in parts of ray-traced frames that are typically noisier due to rays not being sampled.
Ray Reconstruction’s latest iteration is able to unify denoising capabilities along with DLSS Super Resolution into a single model, bringing in efficiencies as it analyzes temporal and spatial engine data to create sharper and more stable images while maintaining high fidelity visuals. The new model is equipped with an efficient denoiser that provides 35 percent more compute capability and can process 20 percent more parameters without missing a beat in performance compared to the previous model.
Along with this, it also builds on the upgrades that are coming to RTX GPUs with DLSS 4.5 Super Resolution, with the model having deeper spatial awareness in every scene. This allows it to be more intelligent in how it uses a game engine’s pixel and motion data for sampling purposes. Thanks to this, it can offer more accurate lighting and better temporal stability, along with clearer and smoother motion for ray tracing and path tracing scenes.
At launch, Nvidia has confirmed that DLSS 4.5 Ray Reconstruction will be capable of running in 27 games, including Everspace 2, Alan Wake 2, Crimson Desert, Cyberpunk 2077, DOOM: The Dark Ages, Directive 8020, Star Wars Outlaws, Indiana Jones and the Great Circle, Pragmata, Resident Evil Requiem, and Hogwarts Legacy, among others.
Features for DLSS 4.5 were first unveiled back in January, with Super Resolution leading the pack in terms of release. At the time, Nvidia had also confirmed that there would be other features and enhancements under the same umbrella, including Dynamic Multi Frame Generation, which is capable of offering a 6X multiplier over previous versions of Multi Frame Generation, which itself could go up to 4X.
Alongside offering smoother frame rates, Dynamic Multi Frame Generation is also capable of offering better synchronization between a user’s graphics card output and their display. Essentially, additional frames are only generated when they are actually needed and if the display can actually support them. This means that, if a user’s display runs at a refresh rate of 144 Hz, Dynamic Multi Frame Generation won’t overshoot that limit at the expense of other performance considerations.
Many of the features in DLSS 4.5 are powered by a new transformer model that was trained on an expanded dataset over its predecessor.
