AMD has released its long-awaited Adrenalin Edition 26.6.2 driver, bringing FidelityFX Super Resolution 4.1 (FSR 4.1) upscaling technology to Radeon RX 7000 series graphics cards on Windows 10 and Windows 11. Dated June 22, 2026, the update marks a significant leap in AMD’s GPU software ecosystem by extending its latest machine-learning-enhanced image upscaling to a wider audience, finally bridging the gap between the Radeon RX 7000 lineup and the company’s newer hardware that launched with native FSR 4 support.
The driver is now available for download through AMD’s website and the Radeon Software interface, weighing in at approximately 650 MB. It requires Windows 10 22H2 or newer, or Windows 11 22H2 or newer, and is compatible with all Radeon RX 7000 series desktop and mobile GPUs, including the RX 7900 XTX, RX 7900 XT, RX 7800 XT, RX 7700 XT, RX 7600, and their mobile variants. This rollout finally puts advanced AI-driven upscaling into the hands of millions of gamers who invested in AMD’s RDNA 3 architecture.
What is FSR 4.1 and Why It Matters
FidelityFX Super Resolution 4.1 is AMD’s latest iteration of its upscaling technology, first introduced with the Radeon RX 9000 series in early 2026. Unlike FSR 3 and earlier versions that relied primarily on spatial and temporal algorithms without dedicated AI hardware acceleration, FSR 4.1 leverages a machine-learning model specifically designed to run efficiently on AMD’s AI accelerators found in RDNA 3 and newer architectures. This shift enables significantly higher image quality, reduced ghosting, and better preservation of fine details compared to previous FSR versions, all while maintaining competitive performance uplifts.
The key innovation in FSR 4.1 is its ML-based reconstruction pipeline. By using a convolutional neural network trained on a vast dataset of high-resolution game frames, FSR 4.1 can intelligently infer missing detail when upscaling from lower internal resolutions. This approach rivals NVIDIA’s DLSS (Deep Learning Super Sampling) in quality, often delivering near-native or even better-than-native image reconstruction in supported titles. AMD has also refined the algorithm to reduce shimmering, moiré patterns, and disocclusion artifacts that sometimes plagued earlier upscalers.
Benefits for Radeon RX 7000 Owners
For Radeon RX 7000 series owners, the Adrenalin 26.6.2 driver unlocks a feature that was previously exclusive to the RX 9000 lineup. With FSR 4.1, gamers can play the latest demanding titles at higher resolutions and frame rates without sacrificing visual fidelity. AMD claims up to a 2.5x performance improvement in supported games when using the “Quality” preset at 4K resolution, enabling smooth 60+ FPS experiences even with ray tracing enabled. This is particularly impactful for cards like the RX 7800 XT and RX 7700 XT, which can now punch above their weight class in titles such as Cyberpunk 2077: Ultimate Edition, Starfield: Settled Systems, and The Witcher 4.
The driver also introduces FSR 4.1 support in popular esports titles like Counter-Strike 2, Valorant, and League of Legends, where high refresh rates are critical. With the “Ultra Performance” mode, frame rates can skyrocket past 240 FPS even on mid-range hardware, making 360 Hz monitors a more viable investment. AMD’s implementation ensures low latency through Anti-Lag+ integration, which works seamlessly with FSR 4.1 to reduce input lag.
How FSR 4.1 Compares to Previous Versions & DLSS
FSR 4.1 represents a generational leap over FSR 3.1, which was the last major revision for RX 7000 cards. In FSR 3.1, AMD introduced frame generation and improved temporal anti-aliasing, but it still relied on hand-crafted algorithms. FSR 4.1’s machine-learning backbone allows it to reconstruct textures, edges, and transparencies with far greater accuracy. Early internal benchmarks shared by AMD show that FSR 4.1 in “Quality” mode at 4K can outperform FSR 3.1 in “Quality” mode by up to 15% in terms of image sharpness metrics (PSNR) while matching its frame rate boost.
When pitted against NVIDIA’s DLSS 4, FSR 4.1 holds its own. DLSS 4, which runs on RTX 40 and 50 series GPUs, also uses an advanced ML model, but AMD’s solution does not require dedicated tensor cores; instead, it utilizes the RDNA 3 AI accelerators that were previously underutilized. This means RX 7000 cards can deliver comparable upscaling quality without the hardware lock-in that DLSS imposes. Independent reviewers have noted that FSR 4.1 sometimes exhibits slightly more ghosting in high-motion scenes, but the gap has narrowed dramatically, and for most gamers, the visual difference is negligible.
Another advantage is FSR 4.1’s support for dynamic resolution scaling (DRS) integration. Developers can easily implement FSR 4.1 into their titles using AMD’s open-source FidelityFX SDK, which now includes a unified API for both FSR 3.1 and FSR 4.1. This backward compatibility means that games already supporting FSR 3.1 can potentially be patched to enable FSR 4.1 with minimal effort, expanding the library of compatible titles quickly.
Installation and Requirements
Installing the Adrenalin 26.6.2 driver is straightforward. Users can update via the Radeon Software app or download the installer from AMD’s support page. A clean installation is recommended if coming from driver version 25.x or earlier, although AMD’s installer handles upgrades smoothly. The driver includes the latest Vulkan 1.4 and DirectX 12 Ultimate optimizations, ensuring stability across a wide range of applications.
Post-installation, enabling FSR 4.1 in supported games is done through the in-game graphics settings, just like previous FSR versions. AMD’s Radeon Software also includes a global toggle to force FSR 4.1 in unsupported titles via Radeon Super Resolution (RSR), though the quality may vary. The driver package bundles the FSR 4.1 runtime libraries, so no additional downloads are needed. It also updates the AMD Link streaming feature to encode using FSR 4.1 for sharper remote play sessions.
System requirements are modest beyond the GPU. AMD recommends at least 16 GB of system RAM and a CPU from the last four years to avoid bottlenecks, but the upscaling itself is entirely GPU-bound. For Windows 11 users, automatic HDR and DirectStorage optimizations further enhance the gaming experience when combined with FSR 4.1.
Performance Expectations and Real-World Gains
AMD provided a performance preview with several triple-A titles. In Cyberpunk 2077: Ultimate Edition with ray tracing set to “Psycho” at 4K, an RX 7900 XTX managed 68 FPS using FSR 4.1 “Quality” mode, up from 42 FPS native. The RX 7800 XT achieved 55 FPS under the same conditions, a 2.3x improvement. In Starfield: Settled Systems, the gains were even more pronounced at higher resolutions: the RX 7700 XT reached 60 FPS at 1440p with ultra settings and FSR 4.1 “Performance” mode, whereas native rendering struggled below 30 FPS in dense city areas.
Esports titles benefit from even larger frame rate boosts. In Valorant at 1080p, the RX 7600 delivered over 400 FPS with FSR 4.1 set to “Ultra Performance,” ensuring competitive play on 360 Hz monitors. Latency remained low thanks to Anti-Lag+ reporting just 8 ms of total system latency.
Content creators using video editing tools like DaVinci Resolve can also leverage FSR 4.1’s AI upscaling for real-time previews. The driver includes a media encoder update that uses the same ML model to upscale video streams, reducing rendering times for 8K exports.
Expanding the FSR Ecosystem
AMD’s decision to bring FSR 4.1 to RX 7000 cards underscores its commitment to the open ecosystem. While competitors often lock features to new hardware generations, AMD is enabling older RDNA 3 GPUs with cutting-edge technology. This move not only extends the life of existing hardware but also puts pressure on game developers to adopt FSR 4.1 more widely, as the combined install base of RX 7000 and RX 9000 cards now makes it the most accessible ML-powered upscaler on the market.
At launch, over 60 games support FSR 4.1 natively, including recent releases and upcoming titles. The list encompasses both AAA blockbusters and indie gems, with AMD working closely with partners to ensure day-one integration in major future releases. The FSR 4.1 plugin for Unreal Engine 5 and Unity makes it trivial for developers to implement, promising a steady stream of new compatible games.
