Nvidia DLSS 4.5 Ray Reconstruction: these games support it from day 1
Nvidia has unveiled DLSS 4.5 Ray Reconstruction, bringing a new AI model that Team Green claims improves ray-traced image quality with cleaner visuals, more accurate lighting, and reduced ghosting on all GeForce RTX GPUs. It will become fully available "in August", with 27 games set to have support for the tech.
Nvidia has announced DLSS 4.5 Ray Reconstruction, a major upgrade to its AI-powered ray tracing pipeline that promises noticeably better image quality across all GeForce RTX GPUs. Building on the DLSS 4.5 suite introduced earlier this year, the update adds a second-generation transformer model designed to improve how ray-traced and path-traced scenes are reconstructed.
Unlike traditional denoisers that rely on hand-tuned algorithms, DLSS Ray Reconstruction uses an AI model trained on Nvidia supercomputers to generate cleaner, more accurate pixels in areas where rays were not sampled.
The biggest change comes from a new transformer model that acts as both a denoiser and image reconstruction system. Nvidia says the updated model delivers 35 per cent more compute capability and processes 20 per cent more parameters while maintaining performance levels similar to its predecessor. The company claims this translates into improved lighting accuracy, better temporal stability, reduced ghosting, and clearer motion in demanding ray-traced workloads. Upscaling routines have supposedly received an improvement as well.
The technical advancement relies on a direct evolution of DLSS 4.5 Super Resolution. Therefore, the current model presents greater spatial awareness in each scene and makes better use of the motion data from the graphics engine. In addition, Nvidia trained the AI on an expanded database to bring the visual reconstruction closer to reality. In short, these changes ensure better lighting accuracy and temporal stability. Similarly, the new tool offers developers refined control over temporal accumulation to precisely adjust images.
NVIDIA also demonstrated advancements in Alan Wake 2, specifically in the representation of CRT televisions. In the classic static scene, noise lines are now displayed individually more sharply, eliminating unwanted blurring. When it launches in August, DLSS 4.5 Ray Reconstruction will be compatible with an initial list of 27 games for all RTX hardware owners.
Despite the new update, the absence of DLSS 5 was felt during the conference. The technology was originally mentioned at GTC 2026, sparking mixed reactions in the community due to the impact of artificial intelligence on image fidelity. To date, no details have been provided regarding a possible postponement or reformulation of the project, with the manufacturer maintaining its current focus on optimizing the DLSS 4 line.

DLSS 4.5 Ray Reconstruction also benefits from a significantly expanded training dataset. According to Nvidia, the larger dataset allows the model to better identify and utilise the most accurate game-engine data, helping reconstruct scenes closer to their intended appearance. Developers will also gain finer control over temporal accumulation, enabling more precise tuning for specific visual effects and rendering scenarios. However, it is interesting that Nvidia made no mention of DLSS 5, which was expected to hit the show floor at Computex. Has its development been called off or is Nvidia cooking something else? Only time will tell.
Moving on, Nvidia showcased the improvements in several titles. In Indiana Jones and the Great Circle, the new model reportedly reduces snow ghosting while producing cleaner particle effects. Pragmata benefits from more responsive lighting effects and fewer visual artefacts, while Alan Wake 2 shows improved stability and clarity in scenes featuring CRT static.
The feature will launch in August through the Nvidia app and will support all GeForce RTX GPUs.
Beyond gaming, Blender 5.3 will integrate DLSS 4.5 Ray Reconstruction as a viewport denoiser later this year. Nvidia also confirmed that multiple games are receiving broader DLSS 4.5 support, including Marvel Rivals, Phantom Blade Zero, Squad, Gothic 1 Remake, Cinder City, Duet Night Abyss and Where Winds Meet.
