AMD has published a recent update citing details over an issue with Windows 11 and Windows 10 that causes the system to stutter and slowdown during use. AMD is now confirming people who may have been experiencing slow system performance or stuttering is caused by their fTPM when enabled.
AMD details the issue as being caused by extended updates and memory transactions between Windows and the system fTPM. The SPI memory that houses the fTPM is basically taking a while to performance each operations while it gets hardware trust confirmation from the fTPM due to the overextend memory transactions.
A workaround has been published in AMD’s update and they are confirming they are working on a permanent solution. AMD does advise that the fix requires switching to a hardware TPM module which has seen prices go for more than $50 despite standard retail rates of $20.
Users switching from TPM 2.0 modules from fTPM are advised to switches off BitLocker first before switching. Other than that, AMD will issue a fix and will distribute it via motherboard partners which is also a solution if you can live with the performance issues for now.
The fix is expected to arrive around May 2022.
