A leaked build of AMD’s FSR 4.1.1 upscaling technology reportedly works on RDNA 3.5 integrated graphics, offering an early sign that newer Ryzen based laptops, handhelds, and mini PCs may eventually receive official support.
The build briefly appeared through Proton Experimental before being removed, but a downloaded copy was tested with several Radeon graphics architectures. The tests reportedly showed that the INT8 based FSR 4.1.1 model could run on RDNA 3 discrete GPUs, older RDNA 2 cards, and RDNA 3.5 integrated graphics.
The most notable result involved the Radeon 890M, an RDNA 3.5 integrated GPU found in higher end Ryzen mobile processors. The technology reportedly ran on the chip through an unofficial tool, suggesting that AMD’s newer upscaling model may be technically possible on these systems.
That does not confirm official support. AMD has not yet announced a release date for FSR 4.1 on RDNA 3.5 integrated graphics, and unofficial testing does not guarantee the same image quality, stability, or performance that a fully optimized driver release would provide.
RDNA 3.5 Devices Could Benefit From a Lightweight FSR Model
Integrated graphics have much tighter power, cooling, and memory limits than desktop graphics cards. This makes advanced upscaling more difficult to run efficiently on laptops and handheld devices.
AMD has already said it is developing a lighter machine learning model for RDNA 3 and RDNA 3.5 integrated graphics. That future version is expected to support products such as thin laptops, compact desktops, handheld gaming PCs, and Ryzen AI systems.
The leaked result suggests that the company’s work may be further along than expected. However, an official version will likely need more testing before it becomes available through standard Radeon software.
| Radeon Architecture | Reported FSR 4.1 Status | Notes |
|---|---|---|
| RDNA 4 | Officially supported | Uses FP8 optimized hardware |
| RDNA 3 | Official support rolling out | INT8 optimized model |
| RDNA 3.5 | Unofficial testing appears successful | Lightweight model planned |
| RDNA 2 | Unofficial testing reported | Official support expected later |
| Ryzen integrated graphics | Future support expected | Depends on AMD’s lighter ML model |
Older Radeon Cards Also Appeared to Run the Leaked Build
Tests also reportedly showed the leaked FSR 4.1.1 file working on an RX 7800 XT and an RX 6900 XT. The RX 7800 XT is based on RDNA 3 and is already part of AMD’s official FSR 4.1 rollout.
The RX 6900 XT result is more interesting because it uses the older RDNA 2 architecture. The test reportedly showed that the feature could be enabled, but visual artifacts were noticed. This may explain why AMD is taking more time to optimize FSR 4.1 for older cards before releasing official support.
FSR 4.1 can improve frame rates by rendering games internally at a lower resolution before using machine learning to produce a sharper final image. This is useful for demanding titles where native resolution performance is limited, especially at 1440p and 4K.
Official Support Will Matter More Than the Leak
Unofficial methods can help enthusiasts experiment with new features, but they can also introduce image errors, crashes, compatibility issues, and unexpected performance changes. The leaked file may show that FSR 4.1 can run on more Radeon hardware, but it does not replace a proper driver release.
For people using RDNA 3.5 integrated graphics, the important news is that AMD appears to have a workable path toward FSR 4.1 support. A lightweight official model could improve gaming performance on devices that do not have a dedicated graphics card, giving handhelds and laptops more room to run newer games at smoother frame rates.
