Nvidia announces that a DLSS 4.5 update for Ray Reconstruction is finally on its way, promising better ray-traced and path-traced graphics for 'similar performance' as the old model

Nvidia Announces DLSS 4.5 Ray Reconstruction Update for Enhanced Graphics

At this year's Computex event, Nvidia revealed a long-awaited update for DLSS Ray Reconstruction, bringing it in line with the rest of the DLSS 4.5 package. This update promises improved ray-traced and path-traced graphics without sacrificing performance, aligning it with the newer DLSS 4.5 features that were previously missing from this critical component of the technology.

DLSS 4.5 was launched in January with a major upgrade to its Super Resolution (upscaling) algorithm. Unlike earlier versions, this update uses a transformer model instead of a convolutional neural network, which improves visual fidelity. However, it also came with a performance trade-off. Around the same time, Dynamic Multi Frame Generation (DMFG) was introduced, but it took some time to roll out fully.

What many users noticed was the absence of updates to Ray Reconstruction (RR). This AI-powered denoiser helps clean up ray-traced scenes and also applies DLSS Super Resolution simultaneously. However, the current version of RR uses an older, less efficient upscaling method, which limits users from enjoying the full benefits of DLSS 4.5.

DLSS 4.5 Ray Reconstruction to Arrive in 27 Games

In August, this situation will change with the arrival of DLSS 4.5 Ray Reconstruction in at least 27 games. Some of the notable titles include Cyberpunk 2077, Doom: The Dark Ages, Alan Wake 2, Pragmata, Resident Evil Requiem, Indiana Jones and the Great Circle, Hogwarts Legacy, and Crimson Desert.

This new version of RR uses a transformer model for its upscaling stage, just like the rest of the DLSS 4.5 suite. Additionally, the AI denoiser is trained on a larger dataset, processing 20% more parameters. This results in improved lighting accuracy, better temporal stability, and clearer motion in ray-traced and path-traced content.

While it's great to finally see a denoiser and upscaler combination that matches the rest of the DLSS 4.5 suite, it’s clear that Nvidia took longer than expected to deliver this update. Although the number of ray-traced games with full DLSS support is not overwhelming, many users would have preferred to see this update sooner than DMFG.

Radeon GPU owners are already familiar with AMD’s AI denoiser, part of the FSR Redstone project. However, there has been no indication that this feature will be expanded beyond the single game it's currently used in, Black Ops 7.
