Microsoft: Disable security features to improve Windows 11 gaming performance

0

If you’ve upgraded a PC to Windows 11 and noticed deteriorating gaming performance, your system may have suffered from Nvidia’s performance issue. Or, and this is another potential cause that Microsoft has just confirmed, it may be suffering because of security features that Microsoft has built into the operating system.

Microsoft has published a support page – Options to optimize game performance in Windows 11 – in which it confirms that game performance may be affected by Windows 11 security features, integrity of code protected by hypervisor (HVCI), short memory integrity, and virtual machine platform. (VMP).

Virtual Machine Platform provides “basic virtual machine services for Windows”. Memory Integrity protects against certain types of process-injecting attacks and ensures loaded drivers are “signed and trusted”.

These features improve threat protections, but they can also impact performance in “certain scenarios and gaming device configurations” according to Microsoft. The support page fails to reveal additional details or information about these scenarios or configurations. This leaves it up to gamers to determine if performance is affected by these security features on Windows 11 systems.

Microsoft notes that disabling features makes the device vulnerable to certain types of threats.

Disabling Memory Integrity

Memory Integrity may not be enabled on many PCs upgraded from Windows 10. It is enabled by default on new systems.

To find out whether it is enabled or not, follow these steps:

  1. Select Start, then Settings.
  2. Open Privacy & Security > Windows Security.
  3. Enable Open Windows Security on the page that opens.
  4. Switch to the Device Security tab.
  5. Click Core Isolation Details on the page under Core Isolation.
  6. Check if Memory Integrity is enabled or disabled.
  7. If enabled, disable it.

Tip: you can reactivate the function at any time by moving the slider to ON.

To disable VPM, follow these steps:

  1. Open Start, type in Windows features and select “Turn Windows features on or off” from the list of results.
  2. Locate Virtual Machine Platform in the list of features you can enable or disable.
  3. Uncheck the box to disable the feature.

Note that a reboot may be required to complete the change. You can undo the change at any time by checking the box again to enable it.

Closing words

Microsoft does not disclose how these security features may impact PC game performance. Since the company has posted a support page that details the issue, it’s almost certain that performance may be noticeably affected.

Whether it’s a good idea to remove these security features to improve gaming performance is up to each Windows 11 user to decide. Many Windows 11 systems may not even have these features enabled by default, especially if they were upgraded from Windows 10.

The first feature update for Windows 11 was released recently. It should now be available on more systems via Windows Update.
