DLSS 4.5 Ray Reconstruction Boosts Ray & Path Tracing on All RTX Cards

Nvidia made headlines again at Computex 2026, unveiling its new RTX Spark ARM processors in partnership with Microsoft. But for gamers already invested in RTX graphics and DLSS, the company delivered another exciting upgrade that promises to elevate ray‑tracing experiences.

Today, Nvidia introduced DLSS 4.5 Ray Reconstruction, an enhanced transformer‑based model that delivers superior image quality in both ray‑traced and path‑traced titles.

According to Nvidia, the new Ray Reconstruction system replaces conventional hand‑tuned denoisers with a supercomputer‑trained AI that refines the noisy pixels left after ray sampling. The model merges denoising and super‑resolution, intelligently leveraging temporal and spatial engine data to produce crisper, more stable, and higher‑fidelity high‑resolution images.

With a 35% increase in compute efficiency and a 20% boost in parameter count, Nvidia claims the performance of DLSS 4.5 will match that of its predecessor. Players can expect noticeably improved lighting and steadier ray‑traced visuals, all without relying on the original image detail.

DLSS 4.5 Ray Reconstruction is slated to launch in August 2026, bringing its advanced denoising capabilities to every generation of Nvidia RTX GPUs—from the 20‑series up through the newest 50‑series cards. While the company has not yet confirmed whether the performance gains will extend to older models, the update promises a broad, cross‑generation rollout.

At launch, 27 titles will support the new Ray Reconstruction model, including high‑profile releases such as Alan Wake 2, Indiana Jones and the Great Circle, Cyberpunk 2077, DOOM: The Dark Ages, and PRAGMATA. This extensive game list signals Nvidia’s intent to make the feature a staple for both developers and players.

Beyond gaming, Nvidia announced that Blender Cycles will incorporate Ray Reconstruction as a denoiser, enhancing real‑time viewport performance for artists. Meanwhile, at Computex, AMD showcased the latest advancements in its Fidelity FX Super Resolution (FSR) upscaling technology, illustrating the competitive push in the industry.
