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 has been releasing major improvements to its DLSS suite of neural rendering tech throughout 2026. The first major update came at CES with DLSS 4.5 upscaling (or "Super Resolution"), which introduced a more advanced and more computationally intensive transformer AI architecture for better image quality at lower input resolutions. The second was DLSS 4.5 Multi Frame Generation, which introduced 5x and 6x multipliers along with a dynamic mode that shifts multipliers on the fly for the smoothest gameplay experience.

Now, at Computex 2026, Nvidia has revealed DLSS 4.5 Ray Reconstruction, its advanced denoiser for better ray-traced and path-traced image quality in games.
