Windows 11: how to improve the performance of your PC while gaming

Some default settings in Windows 11 can negatively affect performance while gaming. Disable them to regain optimal performance.

If you play on PC and have recently upgraded your machine to Windows 11, you may have noticed a performance drop on it during your gaming sessions. Microsoft is aware of this and states on its support pages have found that some hardware configurations may experience a performance degradation. This would be due to two factors: the memory integrity setting and the virtual machine platform (VMP for Virtual Machine Platform). It’s these two options, enabled by default, that can negatively affect your PC’s performance while gaming.

To understand why these two options are slowing down your machine, you have to understand what they are for. The Memory Integrity option is a security option that is part of the Windows Security Center Kernel Isolation module. Enabled by default on all Windows 11 machines, it isolates the Windows kernel from other processes running on your machine. Thus, malware potentially present on your PC, and ready to launch an attack by injecting malicious code, for example, cannot access high-level security processes.

As for the virtual machine platform, also activated by default, it allows, as its name suggests, to virtualize (or emulate) other operating systems on your PC. However, Windows 11 is now officially compatible with Android applications thanks to the Windows Subsystem for Android. So, no doubt for the sake of simplicity, Microsoft has also enabled its virtual machine platform by default.

If you think these two features are responsible for slowing down your PC while gaming, you can turn them off. However, Microsoft advises to deactivate them only temporarily, just while you play, and to reactivate them as soon as your gaming session is over.
