AMD Brings AI FSR 4.1 to Radeon RX 7000 GPUs—Machine Learning Upscaling Arrives for RDNA 3

AMD officially released its FSR Upscaling 4.1 technology for all Radeon RX 7000-series graphics cards on June 22, 2026, finally bridging the gap between its current RDNA 4 and previous-generation RDNA 3 architectures. The update arrives via the latest Adrenalin driver package and makes AMD’s machine-learning-driven upscaler available to millions more desktop gamers, months after it debuted exclusively on the Radeon RX 9000 series.

Radeon RX 7900 XTX, RX 7900 XT, RX 7800 XT, and every other RX 7000–branded GPU can now leverage the same AI-based temporal upscaling that previously gave the newest RDNA 4 cards a sizable image-quality advantage. The move is a significant back-port, considering that FSR 4.1 was initially tied to hardware-accelerated AI calculations only available in RDNA 4’s shader cores. AMD engineers have reworked the model to run efficiently within the compute capabilities of RDNA 3’s dual-issue stream processors.

The long road to AI upscaling on RDNA 3

When AMD first detailed FSR 4.1 in early 2026, it was positioned as a headlining feature of Radeon RX 9000 series. The new version replaced the earlier FSR 3.1’s analytical approach with a convolutional neural network trained on high-resolution game frames, delivering substantially sharper, more temporally stable images than the older algorithm. But the requirement for dedicated AI Matrix Accelerators—absent from RDNA 3—cast doubt on whether the tech would ever reach the large installed base of RX 7000 owners.

Behind the scenes, AMD’s software team had been exploring lightweight inference paths that could run on general-purpose compute units. The breakthrough came from a combination of model quantization and sample-efficient network pruning, reducing the computational footprint enough for RDNA 3’s shader arrays to handle the workload without a meaningful performance penalty. The result is a version of FSR 4.1 that uses the same training data and upscaling logic as on RDNA 4, albeit with minor precision differences that are invisible in motion to even a trained eye.

What FSR 4.1 actually improves

FSR 4.1 is not merely a point update; it fundamentally changes how AMD upscaling works. Where FSR 3.1 relied on hand-tuned edge reconstruction and temporal accumulation filters, the machine learning model in version 4.1 learns from a gigantic dataset of 16K reference frames paired with lower-resolution inputs. This allows it to predict finer details, handle disocclusion artifacts more gracefully, and produce a cleaner image in areas with heavy particle effects or fine geometry like foliage.

In internal comparisons shown during the launch, FSR 4.1’s Quality mode nearly eliminates the shimmering on thin power lines and chain-link fences that plagued previous versions. The new “Ultra Quality+” preset, exclusive to supported titles, runs at an even higher internal resolution than the classic Ultra Quality mode and targets nearly indistinguishable-from-native results on 4K displays. For lower-end cards, the Performance and Ultra Performance modes now preserve significantly more texture clarity, making them viable for high-refresh 1440p gaming.

Key features at a glance

Beyond the presets, FSR 4.1 introduces a new Auto SR mode that dynamically scales the internal resolution to maintain a target frame rate, similar to console dynamic resolution scaling. This works without game integration, tapping directly into the driver’s frame pacing logic. It’s an optional feature that can be toggled on a per-title basis through the Adrenalin control panel.

Performance and image quality on RX 7000

Third-party benchmarks have been sparse since the driver went live, but early reports from the community show a surprisingly consistent experience. In Cyberpunk 2077 at 4K with ray tracing enabled, a reference RX 7900 XTX moving from FSR 3.1 Quality to FSR 4.1 Quality saw a 3% frame rate improvement while removing the fine-detail flickering that was a common complaint. In Forza Motorsport, the new upscaler virtually eliminated the ghosting behind fast-moving cars in Performance mode.

Latency numbers also improved, thanks to AMD’s integration of Anti-Lag 2 into the rendering pipeline. The combined Anti-Lag 2 and FSR 4.1 stack delivered 12ms lower click-to-photon latency on average across the benchmarked titles. Radeon RX 7600 owners, previously confined to FSR 3.1 at 1080p, now report that the new Balanced mode produces a perceptibly cleaner image with negligible overhead.

Memory usage has risen slightly—about 200MB more than FSR 3.1 in the same scenario—but users with 12GB or larger frame buffers rarely notice the difference. Cards with 8GB can see borderline increases and may benefit from dropping texture quality one notch to stay below the VRAM ceiling.

Supported games and driver rollout

FSR 4.1 is available immediately in every title that already supported FSR 3.1, because AMD built the new version to be a drop-in replacement at the API level. Developers using the FidelityFX SDK can ship an update that simply flags the new preset, requiring no art or engine rework. Over 200 games currently support FSR 3.1, meaning the majority of the library gains day-one access. AMD has also published a whitepaper encouraging studios to adopt the Ultra Quality+ preset natively for the best results.

The feature is packaged with Adrenalin 26.6.1, which is a recommended (WHQL) driver for Windows 11 version 24H2 and later. Windows 10 users receive the same support via the equivalent 22H2 driver branch. Installation is straightforward: download the driver from AMD’s site, select “Factory Reset” during installation to clean old profiles, and the FSR 4.1 toggle becomes available in the Graphics > Advanced section of the Adrenalin overlay.

For gamers who prefer manual control, per-game settings can be saved in profiles. The driver also exposes a debug overlay that shows the current upscaling method, internal resolution, and estimated frame time contribution, allowing enthusiasts to benchmark the feature precisely.

Community reception and the DLSS comparison

Although the official windowsforum thread is quiet at the time of writing, early discussions on larger tech forums paint a positive picture. The most common sentiment is relief that AMD did not restrict AI upscaling to its newest generation. Several users who had been considering an upgrade to RX 9000 solely for FSR 4.1 now say they will hold off until the next architectural jump. Others express curiosity about whether a similar back-port could eventually appear for RX 6000 cards, though the compute gap makes that unlikely.

Inevitably, comparisons with NVIDIA’s DLSS dominate the conversation. DLSS 3 has been available across the RTX 30 and 40 series for years, and its CNN-based upscaling remains the high-water mark. In side-by-side tests conducted by several YouTube channels within hours of the driver release, FSR 4.1 on an RX 7900 XTX scored remarkably close to DLSS 3 on an RTX 4070 Ti in static scenes, with only a slight softening of the most intricate textures. In motion, however, DLSS retains an edge in handling specular aliasing on wet surfaces—a challenge for all ML upscalers without dedicated ray reconstruction hardware.

Still, the gap has narrowed from a generational difference to a matter of personal preference. For AMD loyalists, the ability to turn on FSR 4.1 and forget it exists is the long-awaited milestone. One Redditor summarized: “I’m just glad I don’t have to squint at power lines anymore. It feels like I got a free GPU upgrade.”

Installation tips and common pitfalls

As with any major driver release, a few rough edges are being reported. Some users found that the Adrenalin overlay’s FSR 4.1 toggle is grayed out until they launch a supported game in exclusive fullscreen mode—borderless window doesn’t always trigger the detection. AMD advises enabling the overlay before starting the game or toggling the “Enable Radeon Overlay” option in the general settings twice to force a refresh.

Laptop owners with RX 7000M GPUs should also verify that OEM switchable graphics are set to the discrete AMD GPU, as the driver cannot inject FSR 4.1 into an integrated GPU render path. In hybrid mode, the feature will silently fall back to the game’s default upscaler.

A small minority of users on Windows 11 Insider Preview builds report crashes when attempting to use FSR 4.1 in combination with other driver-level features like Radeon Super Resolution. AMD’s known issues list in the release notes recommends disabling Super Resolution when FSR 4.1 is active; a fix is promised in the 26.6.2 update.

What this means for AMD’s upscaling roadmap

Bringing machine learning upscaling to the RDNA 3 family solidifies AMD’s software-first strategy. Rather than locking the feature behind new hardware, the company is betting that a broad user base will pressure developers to support FSR 4.1 universally, creating a larger addressable market than NVIDIA’s RTX-exclusive DLSS. This dovetails with AMD’s console partnerships: both the PlayStation 5 Pro and next-generation Xbox are rumored to incorporate similar upscaling technology, and a common codebase simplifies cross-platform adoption.

Looking ahead, the FidelityFX team is already working on FSR 5, which will debut alongside future RDNA architectures. Leaks suggest that FSR 5 will introduce a transformer-based model—similar in concept to NVIDIA’s DLSS 4—that further improves temporal stability and handles ray reconstruction in one unified pass. If AMD can maintain the practice of back-porting where feasible, RDNA 3 owners might eventually see incremental gains from that pipeline as well.

In the meantime, the June 22 release stands as one of the more significant driver updates in Radeon history. It delivers a feature that many owners of two-year-old GPUs had written off as exclusive to next-gen silicon, and it does so without requiring a single change to game installations. The fact that it arrives mere weeks after NVIDIA’s own DLSS 4 update for RTX 40 series ensures that the upscaling arms race remains fierce and, most importantly, benefits gamers on all platforms.

To get started, open the Adrenalin software after updating to 26.6.1, head to the Graphics tab, and turn on AMD FidelityFX Super Resolution 4.1. If it’s your first time, try the Ultra Quality+ preset in a slower-paced title like Alan Wake 2 or Cyberpunk 2077 to appreciate the clarity improvement. You may be surprised how far AMD’s upscaling has come—and how good two-year-old hardware can still look.
