With Windows 11, Microsoft not only dropped support for many capable processors. But also limited the operating system to hardware including TPM security features. (trusted platform module version 2).
Contrary to the controversial processor requirements. The TPM 2.0 mandate is not really a big deal for most users as most modern devices have this security feature.
TPM is also referred “fTPM” which is a type of security module applied to system firmware instead of dedicated chips in AMD systems. FTPM can easily be enabled on AMD systems. But for some configurations, enabling this feature causes performance issues.
TPM implementation is generally straightforward and one ton of Intel people are using it. But there are some issues with AMD implementation. Especially with audio glitches and staggering frame rates.
The interesting thing is, this problem seems to be due to a compatibility issue between AMD’s FTPM and Windows, not a bug in the new operating system.
