DLSS 4.5 Ray Reconstruction update arrives in August for better ray tracing visuals, broader training data set and second-gen transformer architecture combine for improved image quality

Nvidia announced DLSS 4.5 Ray Reconstruction at Computex 2026, an update to its neural RT denoiser arriving in August. The update introduces a second-generation transformer architecture and a broader training data set. These changes combine to deliver improved ray tracing visuals and better output image quality. The new architecture enhances the denoiser's ability to reconstruct complex lighting effects. The broader training data set helps the model generalize across more scenes and hardware configurations. Builders can expect sharper, more stable ray traced images without additional performance cost.
