AMD FidelityFX Super Resolution 4 now available on GPUOpen

Highlights

The AMD FidelityFX™ SDK v2.0 update includes our cutting-edge ML upscaler AMD FidelityFX Super Resolution 4 (FSR 4). The new ML-accelerated AMD FSR 4 upscaling algorithm is trained using high-quality ground truth game data on AMD Instinct™ GPUs. FSR 4 uses the hardware-accelerated features of the AMD RDNA™ 4 architecture designed to give the user maximum upscaling quality while still providing a next-level gaming experience with a substantial game performance boost.

Visual fidelity improvements

AMD FSR 4 delivers a significant image quality improvement over FSR 3.1 upscaling, with the ML-based algorithm designed to help improve temporal stability, better preserve detail, and reduce ghosting.

Reduced ghosting on moving objects

AMD FSR 4 reduces the ghosting on moving objects and eliminates artifacts from disoccluded surfaces when compared to FSR 3.1. This significantly improves the image quality while playing.

Improved preservation of particle effects

Visual detail within particle effects is now preserved when in motion with AMD FSR 4. With FSR 3.1 the upscaling algorithm was highly sensitive to the absence of motion vectors even when appropriate Reactive and Transparency Masks were provided. This could result in incorrect rendering of particles.

AMD FSR 4’s ML-accelerated algorithm is able to preserve the details from particle systems, even in motion, without requiring developers to provide a Reactive or Transparency mask.

Superior detail and temporal stability

AMD FSR 4 is capable of extracting finer detail, improving image clarity and temporal stability versus FSR 3.1. Flickering is also reduced on small, thin features and high specular surfaces.

Simple API Upgrade Path

This new release of AMD FSR 4 continues to use the FidelityFX API introduced in FSR 3.1, providing an easy update path for developers. New features are exposed using the extensibility of the FidelityFX API. AMD FSR 4 is available as prebuilt, signed DLLs as part of FidelityFX SDK 2.0 official releases to ensure stability and upgradability of DLLs, if allowed by individual game releases.

Unreal Engine 5 plugin

To make it even easier to integrate AMD FSR 4 into titles built with Unreal® Engine 5, we have developed an FSR 4 UE plugin supporting versions from 5.1 to 5.6, the most current release as of this blog publication date. You can download the plugin and learn how to install and use it in our guide.

Automatic updates

With AMD FSR 4, future AMD Software: Adrenalin Edition™ releases can update the version of FSR 4 Upscaling used in-game to the latest version available by default. This ensures players experience the highest quality upscaling without requiring updates for each title.

To expose the versions of AMD FSR available and select a specific version, please see the ‘Version selection’ section of Introduction to the AMD FidelityFX API. Selecting a specific version when creating the FSR 4 context disables automatic updates.

Supported products

To provide superior visual quality at high performance, AMD FSR 4 requires the latest AMD RDNA 4 architecture running on Microsoft Windows® using DirectX® 12.
