DLSS 4.5 Ray Reconstruction rolls out with image quality improvements

Nvidia released DLSS 4.5 Ray Reconstruction in its latest driver drop. The update targets image quality in ray-traced games, smoothing out noise in reflections and shadows without changing performance. KitGuru's first-look testing confirms the cleanup is visible in motion.

Ray Reconstruction replaces hand-tuned denoisers with an AI model trained on cleaner ray-traced renders. It works across RTX 20-series and up — older cards get it too, not just Blackwell. The feature is opt-in per game, so developers need to patch it in. A handful of titles already support it at launch.

The tradeoff: zero FPS hit, but you're adding another layer of AI post-processing to your pipeline. If you're allergic to temporal artifacts or prefer raw raster, you can leave it off. For everyone chasing cleaner ray tracing without tanking frame rate, it's a straightforward win.
