What Windows 11 Virtualization Based Security Does to Gaming Performance

How VBS Impacts Your Gaming Performance

Virtualization Based Security impacts gaming performance by using up system resources to run background checks while you play. This feature drops frame rates, causes stuttering, and increases loading times in demanding games. The performance loss usually ranges from 5 to 10 percent on most systems, though some hardware setups take a heavier hit.

Gamers usually notice this extra load in a few specific ways:

• Lower Frame Rates: Your games might render fewer images per second, making fast-moving action look less smooth.
• Game Stuttering: You might experience sudden pauses or hiccups when you turn quickly or enter a new area in a game world.
• Longer Loading Times: Levels and saved games might take extra seconds to load because the system processor is busy with background tasks.

Independent tests show that keeping this feature active can reduce your game speeds by anywhere from 5 percent to 10 percent. On high-end computer systems, you might still get playable speeds, but you are losing performance that you paid for. On older or mid-range systems, the difference can turn a smooth game into a frustrating, choppy experience.

How to Check If Virtualization Based Security Is Running

Checking if Virtualization Based Security is running takes just a few seconds using the built-in System Information tool. Open the Windows Start menu, type system information, press enter, and scroll down the list to find the Virtualization Based Security status. If it says running, the feature is currently active on your PC.

1. Click the Windows Start button on your taskbar.
2. Type System Information into the search box and press the Enter key on your keyboard.
3. A new window will open with a large list of details about your computer. Look down the list on the right side until you find an item named Virtualization-based security.
4. Check the text next to it. If it says Running, the security feature is active and may be affecting your game speeds. If it says Not enabled, your system is already running without it.

How to Turn Off Virtualization Based Security

Turning off Virtualization Based Security requires disabling memory integrity inside the Windows Security app. Open your settings, go to privacy and security, open Windows security, and change your core isolation settings to turn it off. This action requires a computer restart to apply the changes and restore your missing frame rates.

1. Click the Windows Start button and open the Settings app (the gear icon).

   

2. Click on Privacy & security in the left-hand menu.
3. Click on Windows Security near the top of the list.

   

4. Click the button that says Open Windows Security. A new window will appear.
5. Click on Device security on the left side of the window.
6. Look for the section labeled Core isolation and click on the link that says Core isolation details.
7. Find the switch for Memory integrity and click it to turn it off. Note: This step requires administrator privileges.
8. Close the windows and restart your computer to apply the changes completely.

Once your computer restarts, you can open the System Information tool again to confirm that the feature is no longer running. Launch your favorite game and see if your frame rates and overall smoothness have improved.

Unique Angle: The Hidden Conflict Between Anti-Cheat Software and VBS

Anti-cheat software and Virtualization Based Security conflict because both systems attempt to run deep inside the operating system at the exact same time. This double layer of low-level security forces your processor to work much harder. The clash often leads to unexpected game crashes, severe lag spikes, and lower frame rates in online multiplayer games.

Virtualization-based Security, a feature introduced in Windows 11 version 21H2, often causes up to a 10 percent drop in gaming performance. Virtualization-based Security frequently clashes with game anti-cheat software, which leads to sudden game crashes, freezing screens, and severe frame drops. If your favorite online games crash to your desktop for no clear reason, you can turn off the memory integrity setting to resolve the conflict and stabilize your game.

Unique Angle: Hardware-Level Virtualization Settings in Your BIOS

Hardware-level virtualization settings in your BIOS must be turned off if disabling Virtualization Based Security in Windows does not work. Many motherboards keep virtualization enabled at the hardware level. This means you must restart your computer, enter the BIOS menu, and turn off the hardware setting manually to stop it completely.

To check your processor settings, restart your computer and press the key displayed on your screen—such as Delete, F2, or F12—to enter the BIOS setup menu. Look for settings with names like Intel Virtualization Technology, AMD-V, or SVM Mode. Disabling these hardware virtualization settings will completely shut down virtualization at the processor level. Keep in mind that turning off hardware virtualization in the BIOS will also stop you from running virtual machines or certain programming tools, so only use this method if you do not use those features.

Summary

Virtualization Based Security protects your PC from malware, but this feature often slows down games and causes stuttering. Turning off Virtualization Based Security through your Windows security settings and checking your computer BIOS helps you recover lost frames. Disabling it can make your games run noticeably faster if you experience performance drops.
