Gamers chasing every last frame have long eyed Windows’ Virtualization-Based Security feature with suspicion. Turn it off, they say, and watch frame rates climb. Tests back them up. Yet many who disable it don’t keep it that way. The security price feels too steep.

The Persistent Performance Tax

Virtualization-Based Security, or VBS, creates an isolated memory region using hardware virtualization. It sits apart from the main Windows kernel. The goal? Stop kernel-level malware and unauthorized drivers from taking over. Features like Memory Integrity, also known as HVCI, enforce strict code checks before anything runs in that space.

But every CPU call now routes through an extra layer. That adds overhead. In CPU-heavy games the hit shows up clearly. Benchmarks from recent years put the average loss between 5% and 10%. Some titles see more.

A MakeUseOf test published today delivered 11.3% better 1% lows after disabling VBS on a Ryzen 5 5600 and RX 5600 XT system with 16GB DDR4. Apex Legends jumped from 65-75 fps lows to 78-89. Average frames moved less dramatically, from 140 to 143. In Assassin’s Creed Black Flag the lows improved from 28-34 to 30-33 while averages stayed near 54-55 fps. Cinebench multi-core scored 4% higher with VBS off.

These results line up with broader testing. A 2025 Neowin report on ComputerBase benchmarks found an 8% penalty on a Ryzen 5800X3D even under Windows 11 24H2. CPU-bound scenarios suffered most. Microsoft Flight Simulator often shows 10-15% gains when VBS is disabled, according to multiple guides including one from Gaming Style’s 2026 optimization roundup.

Counter-Strike 2 gained 6.3% and Cyberpunk 2077 about 7.4% in that same analysis. The pattern holds. Modern hardware with MBEC or GMET mitigations reduces the penalty but does not eliminate it. Older CPUs without those helpers lose even more, sometimes 15% or higher.

Stuttering tells a bigger story than raw averages. Frame-time consistency improves noticeably when the hypervisor layer disappears. Players report smoother feel in competitive titles where 1% lows matter most. Yet the gains shrink at 4K where GPU limits dominate.

And Microsoft keeps the feature on by default for fresh Windows 11 installs. OEM systems often ship with it active too. Major updates can flip it back on without warning. Users must check after every significant patch.

Verification is straightforward. Run msinfo32 and look under System Summary for “Virtualization-based security.” If it says “Running,” VBS is active. The quickest toggle lives in Windows Security under Device Security and Core Isolation. Turn off Memory Integrity. A full disable may require registry changes at HKEY_LOCAL_MACHINESystemCurrentControlSetControlDeviceGuard, setting EnableVirtualizationBasedSecurity to 0, or using Group Policy.

Restart, confirm the change, and test. But don’t expect the setting to stay off forever. Windows updates have a habit of re-enabling it.

The Security Tradeoff That Changes the Equation

Disabling VBS removes a key barrier against sophisticated attacks. It weakens protection for credentials and allows unsigned or vulnerable drivers to load more easily. Kernel exploits become more feasible. The Vulnerable Driver Blocklist that many anti-cheat systems rely on ties directly to these features.

Riot Games highlighted this in its recent Vanguard update documentation. The anti-cheat requires VBS and HVCI on supported systems to block DMA attacks and enforce driver integrity. Riot’s August 2026 post explains how the hypervisor runs at a higher privilege level than the OS kernel itself, making it far harder for cheats to operate at ring 0.

That same protection matters outside competitive play. Everyday threats target kernel vulnerabilities. Banking sessions, work documents, or family-shared PCs carry higher risk when VBS is absent. A dedicated pure gaming rig with no sensitive data faces lower stakes. Even then, the calculus isn’t simple.

Shaheer Khan, author of the MakeUseOf piece, gained those 11% better lows yet chose to re-enable VBS. “I won’t leave it off,” he concluded. The exposure to malware and credential theft outweighed the frame-time gains on his mid-range hardware. Many testers echo this view after initial excitement fades.

Hardware matters. Newer Intel and AMD chips with improved virtualization extensions feel the tax less. Yet the feature still extracts a price. Enterprise environments and users handling financial data have little choice but to keep it active. Gamers on high-end systems may shrug off single-digit losses. Budget builds or those chasing maximum competitive edge often disable it and accept the risk.

Recent guides from XDA Developers in July 2026 and SmoothFPS emphasize testing per game and per system. No universal rule fits all. Check after updates. Weigh your threat model. A pure gaming desktop used only for Steam titles carries different risks than a machine that also handles email or browsing.

Other tweaks help too. Hardware-Accelerated GPU Scheduling, Resizable BAR, and proper power plans deliver smaller but additive gains without touching security layers. Combine them with VBS off for maximum results on a dedicated rig. But the core tension remains.

Microsoft has not removed the performance cost despite years of feedback and hardware improvements. The company pushes VBS for hotpatching, better patching compliance, and overall platform defense. Gamers pay a small but measurable tax for that broader protection.

So the debate continues. Disable for frames. Re-enable for peace of mind. Test your own setup. The numbers are real. The decision is personal. And in 2026, VBS still refuses to disappear quietly from the gaming conversation.
