Windows 11 Gaming Issues Explained: Why It Stutters & What Causes It
Windows 11 has at least 4 features enabled by default that directly cause gaming stuttering: VBS (Virtualization-Based Security), Memory Integrity, fullscreen optimizations, and aggressive background services. Disabling VBS alone typically recovers 5-10% FPS and significantly reduces micro-stutters. This guide shows you exactly what to disable, what to keep, and why — with before/after benchmarks. For a broader look at all stuttering causes, see our general stuttering troubleshooting guide.
If you're experiencing stuttering that started after upgrading to Windows 11 (or after a Windows Update), this page has your fix. The most common scenario: games that ran perfectly on Windows 10 now stutter every few seconds.
The step-by-step fixes are in the Windows 11 Fix Wizard.
Windows 11 enables VBS and Memory Integrity by default on newer PCs, adding a virtualization layer that costs 5-10% GPU performance and raises frame-time variability. For about 60% of users, three changes fix the stutter:
- Disable VBS / Memory Integrity — Settings → Privacy & Security → Core isolation → off, then restart.
- Set the power plan to High Performance (or Ultimate Performance).
- Disable Fullscreen Optimizations — right-click the game .exe → Properties → Compatibility.

Before doing anything else, check these 3 things:
Is VBS / Memory Integrity ON?
Windows Security → Device Security → Core Isolation Details
If "Memory Integrity" is ON → This is likely costing you 5-25% FPS
What Windows 11 version are you on?
Win + I → System → About → Windows Specifications
If on 24H2 → Check for the "Optimizations for Windowed Games" bug (see 24H2 section below)
What Power Plan are you using?
Control Panel → Power Options
If "Balanced" → Switch to High Performance (CPU throttling on Balanced causes micro-stutters)
- Fastest fix: Disable VBS/Memory Integrity → Settings → Privacy & Security → Core isolation → OFF
- Check: Is Game Mode ON? (should be ON for most games)
- Check: Power plan → "High Performance" or "Ultimate Performance"
- If stuttering started after update → roll back via Settings → Windows Update → Update History
Windows 11 Gaming Issues Overview
Windows 11 introduces several changes that can impact gaming performance:
VBS (Virtualization-Based Security)
A security feature using CPU virtualization. Protects against kernel attacks but adds 5-25% performance overhead in games. It's a security vs performance trade-off.
New DWM Compositor
Windows 11 uses a different desktop compositor than Windows 10. This affects frame pacing, especially in borderless windowed mode — see our V-Sync and frame pacing guide for how the compositor interacts with sync settings. If you get flickering, black screens, or stutter with G-Sync/FreeSync, disabling Multi-Plane Overlay (MPO) is the most common fix.
More Background Services
Widgets, Teams integration, enhanced telemetry — all consume CPU and RAM in the background even when not actively used.
Auto HDR
Converts SDR games to HDR on HDR monitors. Great when it works, but can cause stutter and visual issues with incompatible games.
What is VBS (Virtualization-Based Security)?
VBS uses CPU virtualization features (Intel VT-x, AMD-V) to create an isolated memory region separate from the main operating system. This protects critical processes from kernel-level attacks — if malware compromises the kernel, it still can't access VBS-protected memory.
Why it affects gaming
Games frequently make system calls that cross between user space and kernel space. With VBS enabled, these transitions have additional overhead because the CPU must context-switch through the hypervisor layer. The impact varies:
- CPU-intensive games: Higher impact (up to 25% in some cases)
- GPU-bound games: Lower impact (often unnoticeable), though VBS/HVCI can still contribute to unexpected GPU usage drops
- Older CPUs: More affected than newer CPUs with better virtualization
What Does Game Mode Actually Do?
Windows 11 Game Mode has evolved since Windows 10. It's now generally beneficial rather than harmful:
What Game Mode enables
- Prevents Windows Update: No background downloads or restarts during gaming
- Priority scheduling: Game processes get higher CPU priority
- Reduces driver reinstalls: Prevents automatic driver updates while gaming
Xbox Game Bar (separate feature)
Game Bar is the overlay system (Win + G) that provides clips, screenshots, and performance monitoring. It runs a separate process that consumes resources even when the overlay isn't visible. Useful if you use Xbox features, but overhead you might not want on a pure gaming PC.
Why Background Services Matter
Windows 11 includes more always-running services than Windows 10. Each one consumes CPU cycles and memory that could go to your game:
Common resource consumers
- Widgets: Constantly fetch web content, news, weather — uses CPU and network
- Microsoft Teams: Auto-starts and runs in background for quick access
- Startup apps: Many programs add themselves to startup silently
- Search indexer: Constantly indexes files, especially after changes
Power plan impact
Windows 11 defaults to "Balanced" power plan which reduces CPU frequency when load decreases. This saves power but can cause micro-stutters as the CPU ramps up and down — similar to thermal throttling in its effect on frame consistency. "High Performance" keeps the CPU ready but uses more power.
Step-by-Step Fixes for Windows 11 Gaming
Apply these fixes in order. Test after each change to identify what helps your system:
Disable VBS / Memory Integrity (Biggest Impact)
- Open Windows Security
- Go to Device Security → Core Isolation Details
- Turn OFF Memory Integrity
- Restart your PC
Set High Performance Power Plan
- Open Control Panel → Power Options
- Select High Performance
- For desktops, enable Ultimate Performance via PowerShell:
powercfg -duplicatescheme e9a42b02-d5df-448d-aa00-03f14749eb61
Disable "Optimizations for Windowed Games" (24H2 Bug)
- Open Settings → System → Display
- Scroll down to Graphics
- Turn OFF "Optimizations for windowed games"
This setting is known to cause stutter in 24H2. Microsoft is working on a fix.
Disable Background Services
- Widgets: Right-click taskbar → Turn off Widgets
- Teams: Settings → Apps → Startup → Disable Microsoft Teams
- Xbox Game Bar: Settings → Gaming → Xbox Game Bar → OFF
- Startup Apps: Task Manager → Startup → Disable unnecessary apps
Configure GPU Driver Settings
NVIDIA: NVIDIA Control Panel → Manage 3D Settings
- Power Management Mode: Prefer Maximum Performance
- Low Latency Mode: On or Ultra
- Threaded Optimization: On
AMD: AMD Adrenalin → Gaming → Graphics
- Anti-Lag: Enabled
- Radeon Chill: Disabled
Disable Auto HDR (If Having Issues)
- Open Settings → System → Display
- Click HDR
- Turn OFF Auto HDR (keep HDR itself on if you want it)
Auto HDR can cause frame pacing issues in games that don't support it well.
Add Game Folders to Defender Exclusions
- Open Windows Security → Virus & Threat Protection
- Click Manage Settings under Virus protection settings
- Scroll to Exclusions → Add or remove exclusions
- Add your game folders (e.g., Steam\steamapps, Epic Games, etc.)
Windows 11 24H2 Specific Issues
Windows 11 24H2 (released late 2024) introduced several gaming-related bugs. If you're on 24H2:
"Optimizations for Windowed Games" Bug
This new setting in Display → Graphics causes stutter and frame pacing issues in many games. Turn it OFF. Microsoft has acknowledged this issue.
DWM (Desktop Window Manager) Changes
24H2 uses a new frame presentation model. Some games running in borderless windowed mode experience different frame pacing than on 23H2. Try exclusive fullscreen if you notice issues.
VBS Re-enabled After Update
Some users reported that VBS was re-enabled after upgrading to 24H2. Re-check your Core Isolation settings after any major update.

Common myths about Windows 11 gaming
"Windows 11 is always worse for gaming than Windows 10."
With VBS off and proper settings, performance is nearly identical. Windows 11 also offers DirectStorage and better Auto HDR for supported titles.
"Debloating scripts make Windows faster for gaming."
Most "debloat" scripts remove things that don't impact gaming. Some break Windows Update, security, or game launchers. Manual targeted changes are safer.
"Disabling all visual effects improves FPS."
Desktop visual effects are GPU-accelerated and have negligible impact on game performance. The ugly "Classic" theme doesn't help gaming.
"You should disable Windows Defender for gaming."
Modern Defender has gaming optimizations and minimal impact. Disabling it exposes you to malware. Add game folders to exclusions instead if concerned.
Important considerations
Disabling it reduces protection against kernel-level attacks. Only disable on dedicated gaming PCs, not machines handling sensitive data.
Many are outdated, break things, or bundle malware. Make changes manually through Windows Settings.
Major feature updates may re-enable VBS or change power settings. They can also install incompatible GPU drivers automatically — see our driver issues guide for how to handle this. Re-check configuration after updates.

Frequently Asked Questions
Why is Windows 11 so bad for gaming?
Windows 11 isn't inherently bad for gaming, but it ships with VBS (Virtualization-Based Security) and Memory Integrity enabled by default on newer PCs. These security features add a virtualization layer that costs 5-10% GPU performance and increases frame time variability. Combined with aggressive background services and telemetry, this creates noticeable stuttering that Windows 10 didn't have.
How do I fix game stuttering on Windows 11?
Start with these 3 steps: 1) Disable VBS — open msinfo32, check if Virtualization-based security says 'Running'. If yes, disable it in Core Isolation settings. 2) Set power plan to High Performance. 3) Disable fullscreen optimizations by right-clicking your game .exe → Properties → Compatibility. These three changes fix stuttering for about 60% of users.
Does Windows 11 24H2 cause stuttering?
Yes, Windows 11 24H2 introduced additional stuttering for many gamers. Specific issues include Auto HDR conflicts, new memory management changes, and updated GPU scheduler behavior. If stuttering started after the 24H2 update, you can roll back within 10 days via Settings → System → Recovery → Go Back. Several hotfixes have been released — make sure you're on the latest cumulative update.
Is Windows 11 worse for gaming than Windows 10?
Out of the box, Windows 11 can be slightly worse due to VBS/Memory Integrity being enabled by default and additional background services. However, with proper optimization, Windows 11 performs similarly to Windows 10 and offers some advantages like DirectStorage and Auto HDR for supported games.
What is VBS and why does it hurt gaming performance?
VBS (Virtualization-Based Security) creates isolated memory regions using hardware virtualization. This adds overhead to certain operations, particularly those involving kernel transitions — common in games. The impact ranges from 5-25% depending on the game and CPU. It's a security feature, not a bug.
Is it safe to disable Memory Integrity?
Disabling Memory Integrity reduces protection against certain kernel-level attacks. For dedicated gaming PCs that don't handle sensitive data, the risk is low. For work machines or PCs handling banking/sensitive info, keep it enabled and accept the performance trade-off.
Should I enable or disable Game Mode?
Modern Game Mode (Windows 11 22H2+) generally helps by preventing Windows Update during gaming and prioritizing game resources. Try it ON first. Only disable if you experience specific issues — some older games or streaming software may conflict with it.
Does Hardware-Accelerated GPU Scheduling help?
HAGS can reduce latency and improve frame pacing on modern GPUs (NVIDIA 10-series+, AMD 5000+). However, it can cause issues with some games or capture software. Enable it, test your games, and disable if you see problems.
Why did my games start stuttering after a Windows Update?
Windows Updates can reset settings (like VBS), introduce driver incompatibilities, change scheduler behavior, or update GPU drivers automatically. After major updates, re-check VBS status, power plan, and consider clean GPU driver install.
Should I disable Fullscreen Optimizations?
FSO (Fullscreen Optimizations) allows borderless-like behavior for fullscreen games. Some games work better with it disabled (especially older titles or games with their own borderless mode). Test per-game — there's no universal answer.
Is it worth staying on Windows 10 for gaming?
Windows 10 support ended in October 2025, meaning you're no longer receiving security updates. While gaming performance may be equal or slightly better on Win10, the security risk increases over time. Plan your transition to Windows 11 — with proper optimization, performance is comparable.
What is Ultimate Performance power plan and should I use it?
Ultimate Performance is a hidden power plan that prevents the CPU from downclocking at all. It's ideal for desktops where power consumption isn't a concern. For gaming, it eliminates micro-stutters caused by CPU frequency ramping. Enable it via PowerShell: powercfg -duplicatescheme e9a42b02-d5df-448d-aa00-03f14749eb61
Can I roll back from Windows 11 24H2 to 23H2?
Yes, within 10 days of upgrading. Go to Settings → System → Recovery → Go Back. After 10 days, you'd need a clean install. If 24H2 is causing game issues, rolling back is a valid option while waiting for Microsoft to patch known bugs.
Will disabling VBS expose me to viruses?
VBS protects against advanced kernel-level attacks, not everyday malware. Windows Defender still protects you from viruses whether VBS is on or off. The risk of disabling VBS is low for most home users, especially on dedicated gaming PCs that don't handle sensitive work.
Why does stuttering only happen sometimes, not constantly?
Intermittent stuttering often indicates background interference — Windows Update downloading, Defender scanning, indexer running, or scheduled tasks. Use Task Manager and Resource Monitor during gameplay to identify periodic spikes. Also check for thermal throttling that occurs after extended play.
