Background

AMD introduced its FidelityFX Super Resolution 4 (FSR 4) AI upscaling and frame‑generation technology alongside the RX 9000‑series graphics cards in March. Marketed as a rival to Nvidia’s DLSS 4, FSR 4 promises to deliver higher performance while preserving crisp, high‑definition visuals through machine‑learning algorithms that predict and compensate for lost pixels during low‑resolution rendering.

New Driver Update

The company’s most recent driver, version 25.9.1, expands FSR 4 support to the majority of games that already support FSR 3.1 with DirectX 12. Users can enable the feature by flipping a toggle in the AMD Software: Adrenalin Edition application. This toggle forces the driver to override the game’s native FSR 3.1.0 implementation with the newer FSR 4 version, allowing the AI‑based upscaling to take effect across a broader library of titles.

Scope of Support

With this driver release, AMD officially lists support for more than 85 games. Notable titles that have received FSR 4 integration include Cyberpunk 2077, Ghost of Tsushima, and F1 25. The rollout continues to add FSR 4 to additional games, gradually increasing the technology’s reach within the gaming ecosystem.

Technical Advantages

FSR 4 utilizes machine‑learning (ML) algorithms to intelligently predict missing pixel data, delivering performance gains without sacrificing visual fidelity. AMD claims the technology provides a “significant leap forward” over its predecessor, FSR 3, by delivering results that are comparable to native resolution rendering while maintaining higher frame rates.

Impact on Gamers

For PC gamers, the ability to enable FSR 4 across a wide array of existing titles simplifies the process of adopting AI‑enhanced upscaling. By offering a single toggle within the driver software, AMD reduces the need for developers to ship separate FSR 4 patches for each game. This approach can lead to faster adoption, broader compatibility, and an overall smoother gaming experience for users with compatible hardware.

Competitive Landscape

AMD positions FSR 4 as a direct competitor to Nvidia’s DLSS 4, emphasizing its cross‑vendor compatibility and the ability to work with any DirectX 12 game that already supports FSR 3.1. By expanding the technology’s availability through a driver update rather than game‑specific patches, AMD aims to accelerate its market penetration and provide an alternative AI‑upscaling solution for a diverse range of gamers.
