Key Questions

Quick answers

Which graphics cards are compatible with the new FSR 4.1 machine learning features?

The ML-powered features of FSR 4.1 are locked to the new RDNA 4 architecture, specifically the Radeon RX 9000 series. Owners of older hardware, such as the RX 7000 and RX 6000 series, will instead use analytical fallback modes labeled as FSR 3.1.5.

What are the software and operating system requirements for the FSR Redstone suite?

To use the full suite, including Frame Generation 4.0 and Ray Regeneration 1.1, users must have Windows 11 and a GPU capable of Shader Model 6.6. The software also relies on the DirectX 12 Agility SDK 1.710.2, though FSR 3.1.5 fallbacks remain compatible with Windows 10.

How does the new DLL-based architecture benefit players in older games?

The shift to a DLL-based architecture allows for driver-side updates via the Adrenalin software rather than requiring game-specific patches. This means users may see improvements in upscaling quality for older titles without waiting for a developer to update the game.

What performance improvements does the Radeon RX 9000 series see with these features?

AMD internal testing shows the Radeon RX 9070 XT achieves an average 3.5x performance increase at 4K resolution when the full Redstone suite is active. However, early third-party reports suggest that while image detail has improved, the technology still trails Nvidia’s DLSS 4.5 in overall image stability.

What is FSR Ray Regeneration 1.1 and which games support it?

Ray Regeneration 1.1 is a new technology designed to clean up lighting and reflections in ray-traced titles to compete with Nvidia’s Ray Reconstruction. As of the current release, Crimson Desert is the first game confirmed to support this specific feature.
