VBS / HVCI Reducing Gaming Performance
What is this error?
Virtualization-Based Security (VBS) and Hypervisor-Enforced Code Integrity (HVCI) are enabled, reducing gaming FPS by 5-25%.
Common causes
- Windows 11 enables VBS by default on new installs
- Windows update enabled VBS/HVCI
- OEM pre-enabled VBS for security certification
- BIOS virtualization settings changed
How to fix it
- Disable Memory Integrity in Windows Security
- disable VBS via Group Policy if needed

VBS (Virtualization-Based Security) and HVCI (Memory Integrity) create a secure hypervisor environment that protects Windows — but costs 5-25% gaming FPS depending on the game and hardware.
Windows 11 enables this by default on new installations and some updates turn it on.
How to check if it's enabled:
1. Press Win+R, type 'msinfo32', press Enter. Look for 'Virtualization-based security' — if it says 'Running', VBS is active
How to disable for better gaming performance:
- Open Windows Security > Device Security > Core Isolation Details > turn OFF 'Memory Integrity'
- Restart your PC
- If Memory Integrity toggle is greyed out, a driver may be incompatible — the error message tells you which driver
- For a full VBS disable: open Group Policy Editor (gpedit.msc) > Computer Configuration > Administrative Templates > System > Device Guard > Turn On Virtualization Based Security > Disabled
- In BIOS, you can also disable 'Intel VT-x' or 'AMD SVM' — but this breaks Hyper-V, WSL2, and Docker if you use them
- Note: disabling VBS reduces security. It's a trade-off between security and gaming performance. Re-enable it for sensitive work
When to seek help
If this error keeps happening after trying the fixes above, it may point to a deeper hardware or system issue. Consider professional help if:
- The crash occurs across multiple games or applications
- You see the same error after a clean Windows install
- Your PC is less than a year old (could be a warranty issue)
- You smell burning or hear unusual sounds from your PC
