What you need to know
- AMD has confirmed that an issue can cause intermittent performance stutters on PCs running Windows 11 or Windows 10.
- Some PCs perform extended fTPM-related memory transactions, which can cause stuttering.
- AMD is working on a permanent fix that should arrive in early May 2022.
Some PCs running on AMD hardware are running into performance stutters. PC owners on Reddit have discussed the stuttering for several weeks, and the issue has now been confirmed by AMD.
According to AMD, stuttering occurs when a system performs an extended fTPM-related memory transaction. When this happens, a computer will stop being responsive for a short period of time. People have also reported robotic audio and video that are likely caused by the same issue.
Here's the description of the bug from AMD:
A permanent fix is on the way for the stuttering problem, but PC owners will have to wait some time to receive it. AMD states that fixing the problem will require a motherboard system BIOS update. Flashable files with the system BIOS update should start shipping in early May 2022, though the exact date the update rolls out will vary from system to system.
For now, there is a workaround for the issue, which AMD explains in a support document:
AMD warns that it is critical to disable TPM-backed encryption systems when switching a PC from fTPM to dTPM. You also need full admin access to perform the workaround.
