AMD adds FSR 4.1 support to Radeon RX 7000-series in Adrenalin drivers

AMD has added support for FSR 4.1 to Radeon RX 7000-series cards in its latest Adrenalin drivers, following last year’s accidental GitHub source-code drop that opened the door for modders. The 26.2.2 driver set offers little else beyond game support for Assassin's Creed Black Flag Resynced and Doom: The Dark Ages | Revelations, but FSR 4.1 is the standout addition.

FSR 4.1’s AI-powered upscaling and frame generation represent a clear improvement over FSR 3 and are described as almost on par with Nvidia’s DLSS 4.5 suite. If a game lacks native FSR 4.1 support, users can enable it via an override in Adrenalin, provided the title implements FSR 3.1 natively.

Implementations on RDNA 3 are likely to be less performant than RDNA 4 versions because RX 7000 cards have far lower matrix-operation ability than RX 9000 chips. That can produce a trade-off between performance uplift and visual fidelity—for example, comparing an RX 9070 XT with an RX 7800 XT—though enabling FSR 4.1 on an RDNA 3 card will still deliver a performance boost.
