Windows 11 gaming performance can drop by 25-30%

Despite Microsoft’s claims that Windows 11 is ideal for gamers, users need to be careful. The fact is that the default settings for security features can reduce game performance by about 25-30%.

The problem is with the Virtualization Based Security (VBS) feature that was available with Windows 10. It virtualizes hardware and software to improve system security. Basically, the platform creates an isolated subsystem that helps prevent malware from entering your computer.

VBS uses hardware virtualization features to create and isolate a safe area of ​​memory. Windows can use this “virtual protected mode” for a range of security solutions, providing significantly better protection against vulnerabilities in the OS and preventing malicious exploits that try to bypass security. ” The function is available primarily to corporate clients.

When upgrading from Windows 10 to Windows 11, VBS will not turn on if not previously used. The problem may occur on new computers with Windows 11 preinstalled. Microsoft previously stated, “As part of our collaboration with our OEM partners and semiconductor manufacturers, we will be activating VBS and HVCI on most new PCs over the next year. And we will continue to look for opportunities to expand VBS to more systems over time. ”

PC Gamer editors tested a number of games on the current build of Windows 11 with VBS turned off and on (and not even running). Far Cry New Dawn performed best, with only a 5% drop in frame rates. At the same time, Horizon Zero Dawn had a drawdown of 25%, Metro Exodus – 24%, and Shadow of the Tomb Raider – as much as 28%. 3DMark Time Spy results dropped by 10%.
