NVIDIA announces DLSS 4.5 in August

Nvidia said on May 31 that DLSS 4.5 Ray Reconstruction will launch in August 2026 for all GeForce RTX GPUs, adding a new version of the company’s AI denoising system for ray-traced and path-traced games. The update is part of Nvidia’s broader DLSS 4.5 package and will be distributed through the Nvidia app, according to posts on Nvidia’s GeForce site. Nvidia said the new Ray Reconstruction model uses a second-generation transformer architecture and a broader training set to improve image quality while maintaining performance similar to the prior model. The company also said 27 games will support the feature at launch. ### What is Nvidia actually updating in August? DLSS Ray Reconstruction is Nvidia’s neural rendering system for replacing traditional hand-tuned ray-tracing denoisers in supported games, the company said. In ray-traced and path-traced scenes, denoisers are used to clean up noisy lighting, reflections and shadows generated from limited ray samples. Nvidia said the August release upgrades that part of the pipeline rather than introducing a new upscaling feature. (nvidia.com) Nvidia said DLSS 4.5 Ray Reconstruction is aimed at producing “superior image quality” in ray-traced and path-traced games. The company tied the update to cleaner reconstruction of lighting detail and more stable visuals in motion, according to its GeForce announcement. ### What changed in the new model? (nvidia.com) Nvidia said the new Ray Reconstruction model uses a second-generation transformer design. The company said the model delivers 35% more compute capability and processes 20% more parameters than the previous version while maintaining similar performance. Nvidia said the model also draws on a broader training dataset and improved scene understanding. (nvidia.com) In the company’s description, the updated system has deeper spatial awareness and makes more use of game-engine pixel sampling and motion data when reconstructing ray-traced and path-traced frames. ### Which GPUs and games are covered? All GeForce RTX GPUs will support DLSS 4.5 Ray Reconstruction, Nvidia said, meaning compatibility extends across RTX 20-, 30-, 40- and 50-series cards. The company said the feature will be available through the Nvidia app. Nvidia said 27 games will support DLSS 4.5 Ray Reconstruction at launch. (nvidia.com) The company’s Computex roundup also said developers were continuing to add DLSS 4.5 features across the RTX ecosystem, which Nvidia said now spans more than 1,000 games and applications. ### How does this fit into DLSS 4.5 more broadly? (nvidia.com) Nvidia introduced DLSS 4.5 at CES 2026 with a second-generation transformer model for Super Resolution and additional frame-generation features, according to prior company announcements. Ray Reconstruction was presented later as another major piece of that DLSS 4.5 rollout rather than a separate generation change. (nvidia.com) In January, Nvidia said DLSS 4.5 Super Resolution would run on all GeForce RTX GPUs in more than 400 games and apps. The August Ray Reconstruction release extends that same DLSS 4.5 branding into the ray-tracing denoising stack. ### When can users get it? August 2026 is the release window Nvidia gave for DLSS 4.5 Ray Reconstruction on its GeForce news pages. (nvidia.com) Nvidia also said Blender 5.3 will receive support for the technology in the fall, extending the rollout beyond games. The next concrete step is the August app release for GeForce RTX users and the initial 27-game launch lineup Nvidia has already outlined. (nvidia.com 1) (nvidia.com 2) (nvidia.com 3)
