AMD Adrenalin 26.3.1 Review: FSR4.1 Support, FPS Gains and Fixes Explained

FSR4.1 support remains exclusive to RX 9000 series, leaving RX 6000 and RX 7000 users without expected upgrades.

AMD Adrenalin 26.3.1 drivers add new features, repair bugs, and make other changes to supported GPUs. Expectations for FSR4 and FSR4.1 support for the RX 6000 and RX 7000 series are not satisfied. Official support is still only available for RX 9000 series graphics cards.

We want to make it clear right away that FSR4 and FSR4.1 are not officially available for the RX 6000 and RX 7000 series. You might have thought that older GPUs would get support, given past leaks and discussions about AMD Noise Suppression 2 and other improvements. Still, this version does not include these features.

AMD is still only letting new technologies work on RDNA4 hardware. You can see that only RX 9000 series cards support FSR 4.1, and there are no other specifics about how the quality or features will be better.

Concerns about Market Position and Strategy

AMD is investing heavily in newer technologies while limiting the functionality of older devices. You can see how this method works for people who have RX 6000, RX 7000, and even newer APUs that come out in 2025.

You still can't use FSR4, machine-learning-based upscaling, or frame generation improvements, even if you bought a high-end laptop or a tiny PC with integrated graphics as good as the RX 7600.

We know that AMD's current edge is still its price-to-performance ratio. However, you can also see that it does not lead to upscaling, frame generation, ray reconstruction, or high-end GPU performance. AMD puts cards like the RX 9070 XT and RX 7900 XTX underneath competing goods like the RTX 5090, RTX 4090, and RTX 5080.

Different Versions of Drivers

We see that version 26.3.1 follows AMD's naming system. The number 26 stands for the year 2026, the number 3 stands for March, and the number 1 stands for the first revision of the month.

New Game Features and Support

There is new game support for Crimson Desert and Death Stranding 2 On The Beach. You can expect better performance, including higher FPS, as we discuss further in the testing notes.

Only RX 9000-series GPUs will support FSR4.1. The release notes don't mention any technical explanations or enhancements.

Problems Fixed

In this driver update, we find several essential fixes. When you loaded save files in Cyberpunk 2077 with path tracing turned on, you may have had crashes or driver timeouts from time to time. This problem has been fixed, especially for the RX 9000 series GPUs.

We also see remedies for difficulties with input devices. When you used AMD Software Adrenalin Edition, you may have had times when the mouse or keyboard stopped working. This problem has been fixed.

This fixes system problems that occur when you repeatedly adjust the Adrenalin settings or alt-tab between apps on RX 7000-series and newer GPUs. In these situations, you can expect better stability.

The AMD Noise Suppression feature, which didn't work on the RX 6000 series and later GPUs before, is now working. If you used this feature before, you might see some changes.

Problems that are Known

We still see several problems that need to be fixed. While playing Battlefield 6 on Ryzen AI 9 AX370 computers, you might see crashes or driver timeouts.

When you use AMD Record and Stream in Battlefield 6, the textures may flicker or become messed up. FSR upscaling and frame creation are not working in Adrenalin Software for the RX 9000 series.

Death Stranding 2 On The Beach may crash on the RX 5000 family GPUs. Also, Roadcraft may crash from time to time on the RX 9000 series.

Observations on Performance and Stability

We tested the drivers across three different GPU versions and found they worked consistently. You should see some FPS gains in the RX 6000, RX 7000, and RX 9000 series, especially in Death Stranding 2.

During testing, we didn't see any major crashes or stability issues. The noise suppression feature works, and the system's overall behavior stays the same.

Missing Updates and Feature Expectations

Based on past leaks, we expected enhancements such as AFMF3 and AMD Noise Suppression 2. You may have also heard that INT8-based FSR4 works on older GPUs. This driver does not officially support these features.

These additions wouldn't require many resources, but they are still not available. You can tell that AMD is focusing on new hardware instead of adding features for current users.

Final Thoughts

AMD Adrenalin 26.3.1 drivers correct bugs, make things more stable, and give you a little speed boost. You get better system dependability and some FPS boosts, but there are still just a few key feature changes.

We see that AMD is still improving older GPUs, but there are concerns about feature limitations. The update might improve stability, but it doesn't add any major new features beyond support for the RX 9000 series.
