ML-powered upscaling excellence

AMD FSR™ Upscaling delivers a significant image quality improvement over previous AMD FSR versions, with the ML-based algorithm designed to improve temporal stability, better preserve detail, and reduce ghosting.

Reduced ghosting on moving objects

AMD FSR Upscaling reduces ghosting on moving objects and eliminates artifacts from disoccluded surfaces compared to AMD FSR 3.1. This significantly improves image quality during gameplay.

Improved preservation of particle effects

Visual detail within particle effects is now preserved when in motion with AMD FSR Upscaling. The ML-accelerated algorithm preserves particle system details even in motion, without requiring developers to provide Reactive or Transparency masks.

Superior detail and temporal stability

AMD FSR Upscaling extracts finer detail, improving image clarity and temporal stability versus AMD FSR 3.1. Flickering is reduced on small, thin features and high specular surfaces.

Ease of integration

AMD FSR™ Upscaling continues to use the AMD FSR API (AMD FidelityFX™ API) introduced in AMD FSR 3.1, providing an easy update path for developers. New features are exposed using the extensibility of the API.

AMD FSR Upscaling is available only as prebuilt, signed DLLs as part of AMD FSR SDK (AMD FidelityFX SDK) official releases to ensure stability and upgradability.

Integration overview

AMD FSR Upscaling requires integration using the FSR API (AMD FidelityFX API) and use of the signed binary distribution.

Key integration points:

• Color buffer - Render resolution, should be in linear colorspace (or set FFX_UPSCALE_ENABLE_NON_LINEAR_COLORSPACE flag).
• Depth buffer - Render resolution, inverted depth recommended.
• Motion vectors - 2D motion vectors in screen space.
• Camera jitter - Sub-pixel jitter must be applied during rendering.

For detailed integration guidelines, see our AMD FSR Upscaling documentation.

We provide localization strings for all versions of AMD FSR for use where you refer to AMD FSR in your game. You can find these on our AMD FSR Naming Guidelines page.

Automatic driver updates

With AMD FSR Upscaling, future AMD Software: Adrenalin Edition™ releases can update the version of AMD FSR 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.

Combine with AMD FSR Frame Generation and Radeon Anti-Lag 2

AMD FSR™ Upscaling works seamlessly with AMD FSR Frame Generation and AMD Radeon™ Anti-Lag 2 for ultra-smooth, ultra-responsive gaming at incredible frame rates on AMD Radeon RX 9000 Series graphics cards.

AMD FSR Frame Generation

AMD FSR™ Frame Generation uses state-of-the-art machine learning to generate high-quality intermediate frames, delivering ultra-smooth gameplay on AMD Radeon RX 9000 Series GPUs.

AMD Radeon™ Anti-Lag 2

AMD Radeon™ Anti-Lag 2 reduces the system latency by applying frame alignment between the CPU and GPU jobs.

General integration notes

Use of pre-built, signed AMD FSR API DLLs is required

The AMD FSR™ SDK 2.0+ (FidelityFX SDK) requires developers interact with the SDK using the amd_fidelityfx_loader_*.dll.

• To use upscaling technologies, the amd_fidelityfx_upscaler_*.dll provides access to AMD FSR 2, AMD FSR 3, and AMD FSR Upscaling 4.
• AMD FSR Upscaling 4 requires an AMD Radeon™ RX 9000, RX 7000 or RX 6000 Series discrete GPU or better. It also supports select AMD Ryzen™ processors with integrated Radeon graphics through an optimized ML model. This includes the AMD Ryzen AI Max 300 and 400 Series, AMD Ryzen AI 9 300 and 400 Series, and AMD Ryzen AI/Ryzen Z2 Extreme and Z2 A processors.
• When running on other hardware the API will automatically select AMD FSR 3.1.6.

Sharpening

AMD FSR Upscaling comes with an optional sharpening pass. It is strongly recommended that games expose a sharpening slider – this is a common request from players.

Debug view

AMD FSR Upscaling has a debug view for integration testing. When enabled, motion vectors are displayed on the top left, and blend factor information on the top right. Read more in our AMD FSR Upscaling documentation.

There are more substantial notes in our main documentation pages.

AMD FSR Upscaling quality modes

AMD FSR™ Upscaling maintains the same quality modes from earlier FSR implementations – Native AA, Quality, Balanced, Performance, with Ultra Performance as an optional mode. These vary the amount of scaling to apply to the source image, depending on the quality/performance ratio desired.

Performance

AMD FSR™ Upscaling delivers excellent performance on AMD Radeon™ RX 9000, RX 7000, and RX 6000 Series discrete GPUs. Performance mode upscaling times:

In addition to discrete AMD Radeon GPUs, AMD FSR Upscaling supports select AMD Ryzen™ processors with integrated Radeon graphics through optimized INT8 ML models. Model selection is automatic and based on the target hardware. More capable AMD Radeon 8000S Series integrated GPUs of the AMD Ryzen AI Max 300 and 400 Series (“Strix Halo”, “Gorgon Halo”) processors run the full INT8 model, while more constrained integrated graphics run a highly optimized INT8 model tuned to preserve performance. Because integrated GPUs share system memory instead of using dedicated VRAM, APU upscaling performance may be affected by system memory bandwidth. Performance also depends on the APU’s power and thermal configuration, so actual results on a given platform may vary.
