Quote:Almost everyone in the tech community familiar with Microsoft's upcoming Windows 11 OS knows that it has some stringent system requirements for security reasons and that requires a PC to have TPM 2.0 enabled, Secure Boot, and a processor that the Redmond giant officially lists on its recommended catalog.
 
There are several PCs, like those based on AMD's Ryzen 1000 series or 6th/7th gen Intel CPUs, that are capable of enabling TPM 2.0 and Secure Boot but still aren't listed as supported. That's because these older processors lack Mode Based Execution Control (MBEC) and hence exhibit a greater impact on the performance when running Microsoft's Virtualization-based Security (VBS).
 
UL benchmarks, the creator of popular 3DMark and more, has noted that there can be an impact on the performance, especially related to gaming tasks, due to VBS. It has stated:

Quote:In our testing with pre-release builds of Windows 11, a feature called Virtualization-based Security (VBS) causes performance to drop. VBS is enabled by default after a clean install of Windows 11, but not when upgrading from Windows 10. This means the same system can get different benchmark scores depending on how Windows 11 was installed and whether VBS is enabled or not.
