AMD Adrenalin 26.5.1 Drivers Improve FPS and Fix FSR4 Injection Issues

Newer versions of AMD Adrenalin 26.5.1 Drivers feature game fixes, FSR4 improvements, and performance changes. AMD has released the Adrenalin 26.5.1 drivers, skipping the usual 26.4.1 release. The new driver package primarily focuses on game support, bug fixes, and stability enhancements for a few Radeon GPUs. 

Many users were hoping for more significant additions after the update wait period. Still, the update primarily offers support for upcoming games and fixes for problems with the RX 9000 series graphics cards. The release also includes changes not mentioned in the official release notes, such as FSR4 injection fixes and software interface fixes. Some games also showed performance gains, with different ones showing different gains on different GPUs.

AMD Adrenalin 26.5.1 Driver Overview

The drivers' naming convention remains unchanged. Version 26 indicates the year 2026, 5 indicates the month of May, and 1 indicates the first revision for the month. AMD jumped straight from 26.3.1 to 26.5.1, so people were hoping for even more significant new features.

Some users wanted the Agility SDK to be included in regular releases rather than reserved for preview releases. This feature wasn't included in this update, however.

New Game Support has been added in 26.5.1.

In the new drivers, AMD has added support for several new games, including:

• Pragmata
• Honor of Kings World
• Industria 2
• Tides of Tomorrow
• Mongil Star Dive

In some of these games, observed improvements and changes in stability and performance were observed compared to the previous drivers. The following fixes are included in Resident Evil Requiem: Resident Evil Requiem Stuttering Improvements: Guests of the virtual village will notice one of the biggest fixes is the fixing of stuttering in Resident Evil Requiem, which is known to cause stuttering on RX 9000 series GPUs on the Raccoon City map.

The heavier "stuttering" and occasional crashes occurred in previous drivers, particularly when frame generation was activated. The 26.5.1 drivers provided much smoother, more stable gameplay. Still, there were a few stutters here and there, but they seemed to be related to the game rather than the GPU drivers. The game was once almost impossible to play, and now it is quite functional in most situations.

Battlefield 6 Driver Timeout Issues: How to Troubleshoot

AMD has admitted that Battlefield 6 crashes intermittently on Ryzen AI AX370 systems and can cause the driver to time out. A patch is in the works, the company said. Some AMD graphics cards may also display texture flickering and corruption when using Record and Stream features.

Yet another noted problem is that FSR upscaling and frame generation are disabled in the Adrenalin software while playing Battlefield 6 on RX 9000 series GPUs. But the tests revealed that FSR4.1 injection was functioning properly on Radeon RX 9070 without any apparent issues.

RoadCraft and Satisfactory Issues

AMD also confirmed that RoadCraft crashes and/or times out the drivers on RX 9000 series GPUs from time to time. In the meantime, Satisfactory can still exhibit some graphical issues while playing. Some changes were identified during testing that were not officially reported by AMD.

Some older drivers (26.3.1) were not always able to properly identify compatible FSR 3.1 games. As a result, it has been impossible to inject FSR 4, even if the game supported it. Testing done with both the RX 9070 and RX 9070 XT has shown that this has now been resolved in 26.5.1. FSR4 injection is correct again with the supported titles.

Adrenalin Software Blank Tab Bug Fixed

The other problem was with the Adrenalin software interface. Some tabs within the app would become empty after the launch or play. This was the only way to work around the issue: closing the software entirely and then reopening it.

The issue seems to have been resolved in the current drivers. Performance Improvements in Pragmata and Industria 2. Furthermore, there was an improvement in selected games. Pragmata posted better FPS on some GPUs, including older RDNA 2 graphics cards such as the Radeon RX 6750 XT.

In some scenes, Industria 2 also saw FPS boosts, but the boost varied by GPU. In certain games, such as Industria 2, FPS performance was worse on the Radeon RX 7900 XTX than in Pragmata. Another behavior uncovered in testing was that enabling FSR4 caused frame generation in Industria 2. It is currently not possible to set FSR4 upscaling without frame generation enabled.

Ongoing Questions About FSR4 on RDNA3 GPUs

The discussion continues regarding AMD's intentions for FSR4 support on RDNA3 graphics cards. The discussion continues about AMD's intentions for FSR4 support on RDNA3 graphics cards.

Some feel the delay is related to Steam Machine development. In contrast, others think it's partly due to deals with Sony hardware. Many fans believe that desktop RDNA3 GPUs will support PSSR2 too, given their similarity to FSR4 and their use of RDNA 3 or RDNA 3.5 graphics.

Meanwhile, FSR 4 functionality has been available to Linux users in the official Mesa drivers on RDNA 3 cards. Multiplayer games that support Linux can already run FSR 4 without fear of bans or unofficial changes.

This is why Desktop Windows support is not ubiquitous yet, though. This is one of the reasons why support for Desktop Windows is not available yet on Steam Machines.

Users of the AMD are Still Waiting for More Features

There are some Radeon fans, especially those with older cards, who are still waiting for extra features like AFMF3 or official FSR 4 support for the older GPUs. Even if a reduced-performance version with FP16 emulation is implemented, more options would be available to existing hardware owners.

Because it had been so long since the last driver update, people were hoping for bigger changes than just stable patches and better game support. Instead, 26.5.1 is mostly meant to be a patch that fixes a few problems and improves compatibility. The preview driver was also released by AMD back in April, with improvements for Agility SDK and shader pre-compilation on Windows.

Those features still don't exist in the official 'Adrenalin' driver branch.

AMD Adrenalin 26.5.1 fixes some games in a useful way, improves FSR4 input reliability, and addresses issues with the software interface present in earlier versions. Performance improves in some games, but this depends on the GPU and game engine.

Meanwhile, larger has fewer of its users' favorite features. There is no official clarification on FSR4 support for RDNA3 cards either, leaving many Radeon users in suspense for any further information.
