Redstone Update Overview

AMD’s upcoming software release, internally referred to as “Redstone,” is positioned to enhance both machine‑learning frame generation and ray‑tracing capabilities for the Radeon RX 9000 series GPUs built on the RDNA 4 architecture. The update is expected to incorporate a suite of improvements to FidelityFX Super Resolution 4 (FSR 4), delivering higher image quality while maintaining strong frame rates during upscaling.

Driver Discovery and AFMF 3

The existence of Redstone was hinted at when a user on the Guru3D forums identified a reference to “AFMF 3” (AMD Fluid Motion Frames) inside the driver files slated for the next 25.20 Adrenalin driver. AFMF 3 is a driver‑level frame‑generation tool that builds on the earlier AFMF 2.1 implementation. According to the source, AFMF 3 is designed to lessen ghosting and input lag, offering a more competitive alternative to Nvidia’s Smooth Motion technology.

Potential FSR 4 Backport

In addition to the AI‑upscaling enhancements, Redstone may enable an official backport of FSR 4 to older RDNA 3 GPUs. This speculation stems from AMD’s brief accidental release of FSR 4 as open‑source, which allowed modders to experiment with the technology on legacy hardware. An official backport would provide a smoother, officially supported path for users of older AMD GPUs to benefit from the latest upscaling advancements.

Competitive Landscape

While Nvidia’s DLSS 4 currently leads in terms of image quality, ray‑tracing performance, and frame‑generation features such as Multi‑Frame Generation, AMD’s Redstone aims to close that gap. By improving frame generation, reducing visual artifacts, and extending FSR 4 support, AMD seeks to make its upscaling solutions more attractive across a broader range of devices, including handhelds powered by the Z1 Extreme chip.

Implications for Users

If Redstone arrives as anticipated with the 25.20 driver, it could provide immediate benefits to owners of the Radeon RX 9000 series and potentially to users of older RDNA 3 GPUs. The enhancements would address common concerns such as ghosting, input lag, and the need for third‑party workarounds to access newer upscaling features. Overall, the update signals AMD’s commitment to advancing AI‑driven graphics technologies and expanding their accessibility.
