AMD Launches FSR Redstone on RDNA 4 With ML Upscaling, Frame Generation and Ray Regeneration

A driver-based release confines the suite to RX 9000 hardware, with features appearing progressively across supported games.

Overview

  • AMD rolled out FSR Redstone via the Adrenalin 25.12.1 driver and a new SDK, bundling FSR Upscaling (formerly FSR 4) with ML Frame Generation, Ray Regeneration and the developer-ready Radiance Caching.
  • The new ML features require Radeon RX 9000-series (RDNA 4) GPUs; older cards fall back to non‑ML FSR 3.1 upscaling and frame generation, with no support for Ray Regeneration or Radiance Caching.
  • AMD says more than 200 games support at least one Redstone feature by year’s end, with more than 30 titles confirmed for the ML Frame Generation implementation.
  • Call of Duty: Black Ops 7 is the first game to ship Ray Regeneration, and Microsoft’s Matt Booty says Xbox worked closely with AMD to co-develop the feature, hinting at future hardware use.
  • AMD cites big gains such as up to 4.7x in Cyberpunk 2077 on an RX 9070 XT, though figures were captured in Performance mode with generated frames, and Redstone still uses single-frame generation versus Nvidia’s multi-frame approach.
