Games may run terribly on Windows 11

Fortunately, the security function responsible can be turned off.

More helpful information became well-known before the release of Windows 11 on October 5; UL, the developer of 3DMark measurement software, said a security feature in the operating system could dramatically reduce FPS by as much as a quarter, according to PC Gamer measurements.

Virtualization-based security (VBS) is responsible for the problem, and when it is turned on, the operating system stores some of its processes in a highly protected area of ​​memory. This can make it massively harder for malware to disable certain security features and exploit vulnerabilities that sound in them, which sounds great.

However, VBS is a nightmare for gamers, and even when using processors officially supported by Windows 11, gaming performance can be disrupted. Unsupported CPUs may have a minus even more remarkable because they do not yet include Mode Based Execution Control (MBEC). The PC Gamer tested more games is a modern percussion and desktop computer on and off VBS-sel, measured after activation decreases performance:

  • Far Cry New Dawn: 5%,
  • Horizon Zero Dawn: 25%,
  • Metro Exodus: 24%,
  • Shadow of the Tomb Raider: 28%,
  • 3DMark Time Spy synthetic measurement: 10%.

Virtualization-based security isn’t new, it’s actually available in Windows 10, but it’s inactive at the factory for the lion’s share of users and is usually only enabled on computers in government agencies and companies. The easiest way to enter your configuration page is to look for Core Isolation in Windows Explorer, set in the Memory Integrity section.

Virtualization-based security is also available in Windows 10 but is turned off at the factory.

According to Microsoft, whoever upgrades from Windows 10 to Windows 11 will not have VBS enabled. Still, the company intends to activate it later in as many configurations as possible over the next year. The more you install Windows 11, the more theoretically it will be active at the factory. The same can apply to at least some of the computers that come preinstalled with the system.
