AMD Adrenalin 26.6.4 Known Issues: What It Fixes and Who Should Install It

AMD Software Adrenalin Edition 26.6.4 is a WHQL fix release aimed at two problems Radeon RX 7000 owners have been reporting since 26.6.2: an intermittent install or launch failure on Windows 10, and application crashes in some games with FSR 4.1 Upscaling enabled. If either one hit your PC, this driver is the targeted fix. If your current driver is stable, read the known-issues list before updating.

Bottom line

Install 26.6.4 if you have a Radeon RX 7000 series card and hit the Windows 10 install failure or crashes with FSR 4.1 Upscaling; those are the two fixes AMD lists. Hold off if you play Battlefield 6 on a Ryzen AI 9 HX 370 laptop, where AMD still lists an intermittent crash or driver timeout it is working on with the developer. As with any driver, the version that is stable on your exact PC beats the newest number.

Record a repeatable result before changing the driver so you have a useful comparison.

What AMD officially fixed

AMD's release notes list targeted fixes rather than broad performance changes. Both confirmed fixes concern Radeon RX 7000 series graphics products.

    Current known issues

    These are the problems AMD itself lists as open in the 26.6.4 release notes. A listed issue is not guaranteed to hit every PC; it marks configurations worth testing before you rely on them.

    • Intermittent application crash or driver timeout while playing Battlefield 6 on AMD Ryzen AI 9 HX 370; AMD says it is working on a resolution with the developer.
    • Texture flickering or corruption in Battlefield 6 with AMD Record and Stream on some AMD graphics products.
    • AMD FSR Upscaling and Frame Generation may show as inactive in Adrenalin software while playing Battlefield 6 on Radeon RX 9000 series cards even when enabled.
    • AI Bundle components may fail to install in regions with limited access to Hugging Face and GitHub.
    • Model flickering or rendering failure in Maxon Cinema 4D and Blender, and intermittent Blender crashes, on Radeon RX 7000 series and above.

    Should you install 26.6.4?

    Decide from the fix list and the known issues, not the version number. The driver targets specific RX 7000 problems rather than promising broad gains.

    • Install it if an RX 7000 card fails to install or launch the driver on Windows 10; this failure was introduced around 26.6.2 and this is the official fix.
    • Install it if games crash with FSR 4.1 Upscaling enabled on an RX 7000 card.
    • Wait if you mainly play Battlefield 6 on a Ryzen AI 9 HX 370 machine until AMD closes the listed crash.
    • Wait if your current driver is stable and neither fix applies to your hardware.

    If the driver made things worse

    Change one variable at a time so you can tell whether the driver caused the problem or merely coincided with it.

    • Record the old and new driver versions, Windows version, affected games, and whether FSR Upscaling or Frame Generation was on.
    • Use factory reset in the Adrenalin installer, or Display Driver Uninstaller in safe mode, for a clean reinstall before blaming hardware.
    • Test the affected game once with Record and Stream and overlays disabled; that isolates the listed Battlefield 6 flickering case.
    • If a regression persists, reinstall the last driver that was stable on your PC from AMD's official driver archive, not an arbitrary version copied from a forum.
    • Report repeatable problems through AMD's Bug Report Tool so the issue appears in future release notes.

    FAQ

    Direct answers on the current AMD driver questions.

    • Q: What does AMD 26.6.4 actually fix? A: The Windows 10 intermittent install or launch failure and crashes in some games with FSR 4.1 Upscaling, both on Radeon RX 7000 series.
    • Q: Does 26.6.4 fix the Battlefield 6 crash on Ryzen AI laptops? A: No. AMD still lists the Ryzen AI 9 HX 370 crash or driver timeout as a known issue it is working on with the developer.
    • Q: Is 26.6.4 a performance driver? A: No. AMD's notes list targeted fixes, not new game performance claims.
    • Q: My FSR toggle shows inactive in Battlefield 6 on an RX 9000 card. Is that a broken install? A: Not necessarily. AMD lists the inactive display as a known software-reporting issue on RX 9000 while playing Battlefield 6.
