Boost FPS & Reduce Input Lag – Disable VBS in Windows 11
Your PC might be fighting against you right now. Temps are fine, GPU drivers are updated — but FPS still feels low, and CPU bottlenecks your games. The secret culprit? Windows 11’s hidden virtualization features stealing CPU cycles.
Features like Core Isolation, Memory Integrity, VBS, Device Guard, and Credential Guard are designed for corporate laptops, but on gaming PCs they eat frames and add latency.
In this guide, I’ll show you how to fully disable virtualization bloat in Windows 11 — with proper registry tweaks, CMD commands, BIOS settings, and service cleanup. This unlocks smoother gameplay, higher FPS, and reduced input delay.
🛠️ Commands & Paths Used:
Step 1 – Disable Core Isolation (Memory Integrity)
Windows Security: Core Isolation → Memory Integrity = Off
Registry Path:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\DeviceGuard\Scenarios\HypervisorEnforcedCodeIntegrity
Enabled = 0
Step 2 – Disable VBS (Virtualization-Based Security)
CMD (Admin):
bcdedit /set hypervisorlaunchtype off
Confirm: Run systeminfo.exe → check for
Virtualization-based security: Not Enabled
Step 3 – Disable Device Guard & Credential Guard
Group Policy (Pro):
gpedit.msc → Computer Configuration → Administrative Templates → System → Device Guard → Turn on Virtualization Based Security = Disabled
Registry (Home):
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\DeviceGuard
EnableVirtualizationBasedSecurity = 0
Step 4 – BIOS / UEFI Settings
Disable: Intel VT-x, VT-d, AMD-V, SVM Mode, IOMMU
Location: CPU Configuration → Virtualization Settings
Step 5 – Registry & Service Cleanup
Services (services.msc): Disable Credential Guard, Device Guard, Hyper-V
Registry Cleanup:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa
LsaCfgFlags = 0
CMD verification:
systeminfo | find "Virtualization-based security"
🚀 Steps Covered:
Disable Core Isolation / Memory Integrity
Kill VBS (Virtualization-Based Security)
Shut down Device Guard & Credential Guard
BIOS virtualization settings for gaming PCs
Registry & service cleanup to keep them OFF
