NVIDIA Adds 2nd-Gen Transformer Ray Reconstruction to DLSS 4.5

Posted on
NVIDIA updated Ray Reconstruction with a 2nd-gen transformer model inside DLSS 4.5, improving denoising and spatial lighting accuracy.

Quick Report

NVIDIA expanded DLSS 4.5 with a 2nd-generation transformer-based Ray Reconstruction model, delivering a more efficient AI denoiser and improved spatial lighting awareness for ray-traced scenes.

The update replaces older CNN-based approaches with a transformer trained on larger datasets, improving shadow/reflection fidelity and overall image quality in sampled ray-traced content.
