01.The Cost of Security in Windows 11
In Windows 11, Microsoft enabled features like VBS (Virtualization-Based Security) by default. It uses the Hyper-V engine to create a security "bubble" around your system. While this makes your PC nearly immune to certain types of persistent malware, it creates an extra layer of processing that can "steal" CPU from your games. In 2026, with many-core CPUs, the impact is smaller, but on entry-level processors, the FPS difference is noticeable.

02.1. How to know if Hyper-V is active?
Don't rely just on the features menu. Check the actual status:
- Search for 'System Information' (msinfo32) in Start.
- Scroll to the bottom of the list in the 'System Summary' tab.
- Look for 'Virtualization-based security'. If it says 'Running', Hyper-V is active and impacting your system.
03.2. When SHOULD you keep it active?
Do not turn off if:
- You use Google Play Games for PC.
- You are a developer and use Docker or WSL2.
- You prioritize absolute security over a few extra frames.
Disabling Hyper-V will leave your PC more vulnerable to "Kernel Level" attacks.
04.3. How to safely disable it
If you decided that FPS is more important:
1. Go to 'Turn Windows features on or off'.
2. Uncheck 'Hyper-V', 'Virtual Machine Platform', and 'Windows Hypervisor Platform'.
3. Restart the PC.
Extra Tip: To disable only the security part (VBS) without removing the engine, go to Windows Security > Device Security > Core isolation details and turn off 'Memory Integrity'.
