WHAT JUST HAPPENED? Nvidia has used Computex 2026 to announce DLSS 4.5 Ray Reconstruction, an updated version of its AI denoising technology built around a second-generation transformer model. The feature is coming in August and will be available to all GeForce RTX GPUs through the Nvidia app.
Ray Reconstruction is designed to replace the hand-tuned denoisers traditionally used in ray-traced and path-traced games.
Instead of relying on separate, developer-adjusted filters to clean up noisy lighting, reflections, and shadows, Nvidia's model combines denoising and Super Resolution into one neural network that analyzes temporal and spatial data from the game engine to reconstruct the final image.
The company says the new model delivers 35% more compute capability and processes 20% more parameters while maintaining similar performance to the previous version.
It's also been trained on a larger dataset, which Nvidia says helps it choose the right engine data more accurately and produce lighting closer to ground truth. Developers also get finer control over temporal accumulation.
