Trusted Platform Module (or TPM) is one of the Windows 11 hardware requirements. If you want to run Windows 11 and receive regular updates, your computer must have either a software or hardware-based TPM 2.0 module. We have a dedicated article here on Winaero that describes how to enable TPM on Intel and AMD systems. The latter reportedly suffer from intermittent stutters and performance issues when users turn on TPM.
A user named HarryJDM_ posted a lengthy message on r/Windows11 describing issues with Windows 10 and 11 when running with fTPM (software-based TPM on AMD motherboards). The computer with AMD Ryzen 9 5950X and Asus Prime X570-P motherboard regularly suffers from stutters regardless of what app it runs.

They also provided a video proof with GTA V lagging for a couple of seconds. According to the post, going back from Windows 11 to 10 and disabling fTPM helped fix the issue and eliminate all stutters.
Some users speculate that buggy firmware might be a problem. They also suggested using a dedicated discrete TPM chip. Unfortunately, that does not help. Even systems with a hardware-based Trusted Platform Module annoy their owners with regular performance dips.
The post received a couple of hundreds of upvotes and almost two hundred comments, with many users confirming similar issues on their AMD-based computers. You can follow the discussion here. For now, there is no official information from Microsoft or AMD regarding stutters on systems with TPM.
Windows 11 and AMD CPUs so far have had a somewhat rocky relationship. The latest operating system from Microsoft was causing problems with CPPC (a feature that detects the most powerful core in a CPU) and L3 cache delays. Fortunately, AMD and Microsoft released OS and driver fixes to fix the problems and restore lost performance.
