Nvidia Announces DLSS 4.5 With Ray Reconstruction and Frame Generation Updates Nvidia is expanding its AI-enhanced graphics push with DLSS 4.5, aiming both to sharpen ray‑traced visuals on existing RTX hardware and to dramatically boost frame rates on its next‑generation GPUs.

Early reveal at Computex

At Computex, Nvidia first detailed a new DLSS 4.5 feature called Ray Reconstruction, built on a second‑generation transformer AI model. The company says the model can “generate higher-quality pixels in the noisy parts of a ray traced frame where rays were not sampled,” promising cleaner particle effects and more accurate lighting. Crucially for current owners, Ray Reconstruction is slated to work on all GeForce RTX 20‑series and newer GPUs starting in August.

Beta rollout with the Nvidia app

A day later, Nvidia began rolling out the broader DLSS 4.5 package through its new Nvidia app beta, positioning it as the next major update to its Deep Learning Super Sampling technology. The update targets over 20 supported games, where players can mix performance gains with image‑quality improvements.

The headline feature for future hardware is 6x Multi Frame Generation for RTX 50‑series GPUs. Nvidia says this mode uses a second‑generation transformer AI model to generate “five additional frames for every single natively rendered one,” with “minimal impact” on responsiveness — an increase from the three extra frames possible with DLSS 4.

Alongside that, Dynamic Frame Generation acts “like an automatic transmission for your GPU,” automatically switching between different Multi Frame Generation levels to balance frame rate, image quality, and responsiveness. Users can apply it per game or globally via the Nvidia app’s graphics settings.

Impact on current and future RTX owners

While 6x Multi Frame Generation is reserved for upcoming RTX 50‑series cards, Nvidia is also updating the DLSS Frame Generation Model for RTX 40‑ and 50‑series owners to improve in‑game UI elements such as mini‑maps and HUD overlays. Meanwhile, Ray Reconstruction extends some of the newest AI image‑quality gains back to earlier RTX generations, signaling Nvidia’s attempt to keep existing users engaged even as it prepares its next wave of hardware.
