Quick Answer: Windows 11 25H2 introduced several display and power changes that cause stuttering in games, even on high-end hardware. The fastest fixes are: disable MPO (Multi-Plane Overlay), turn off Game Bar captures, clear the DirectX shader cache, disable VBS (Virtualization-Based Security) if you upgraded from Windows 10, and check for the latest NVIDIA/AMD drivers with 25H2-specific optimizations. Most 25H2 stuttering is fixable without rolling back the update.
Update (May 2026): Microsoft released KB5089573 on May 26, 2026, which resolves several 25H2 gaming issues. Check Settings > Windows Update and install all pending updates before applying the fixes below, some may already be resolved.
If your games ran perfectly smoothly before the Windows 11 25H2 update but now stutter, hitch, or feel choppy despite unchanged hardware, you’re experiencing update-specific conflicts between the new Windows features and your gaming setup. This isn’t a hardware problem, it’s a configuration mismatch that appeared when Microsoft changed how Windows handles overlays, power management, and GPU scheduling in the 25H2 update.
This guide focuses specifically on what changed in 25H2 and how to fix the stuttering it caused. If your stuttering isn’t related to the 25H2 update, you’ll find links to the correct guides at the bottom.
What Is Windows 11 25H2 Stuttering?
Windows 11 25H2 stuttering refers to frame timing issues, micro-stutters, and choppy gameplay that started immediately after installing the Windows 11 version 25H2 update (released late 2025). Unlike general Windows 11 issues that existed in earlier versions, 25H2-specific stuttering is caused by new features and behavior changes Microsoft introduced in this particular update.
Skip straight to Step 1: Disable MPO →
What changed in 25H2 that affects gaming:
MPO (Multi-Plane Overlay) behavior: Microsoft changed how MPO handles overlays and borderless windowed games. The new implementation causes frame presentation delays in many games, especially with Discord, OBS, GeForce Experience, or browser overlays active.
Game Bar auto-capture: Windows 11 25H2 enabled automatic gameplay capture by default for more games. This background recording causes stuttering even when you’re not actively using Game Bar features.
VBS (Virtualization-Based Security) auto-enable: If you upgraded from Windows 10 to Windows 11 25H2, VBS may have auto-enabled during the update. This adds 5-15% performance overhead and causes micro-stutters, especially in CPU-heavy games.
Power throttling changes: 25H2 adjusted how Windows manages CPU and GPU power states during gaming. Some systems now throttle performance more aggressively even in “High Performance” mode.
GPU scheduling refinements: Changes to Hardware-Accelerated GPU Scheduling in 25H2 help some systems but cause stuttering on others, particularly with older GPU drivers that haven’t been optimized for the new behavior.
DirectStorage changes: 25H2 updated DirectStorage implementation. Games using DirectStorage may experience shader compilation stuttering or asset loading hitches if the cached data becomes incompatible.
Why this is different from general Windows 11 issues: If you had smooth gameplay on Windows 11 23H2 or earlier versions and stuttering only appeared after updating to 25H2, these are update-specific conflicts, not general Windows 11 problems. The fixes below target the specific changes Microsoft made in 25H2.
Do You Have Windows 11 25H2-Specific Stuttering? (Quick Self-Check)
You likely have 25H2-specific issues if:
Timing Indicators:
✓ Stuttering started within days of installing the Windows 11 25H2 update
✓ Games ran perfectly smooth on Windows 11 23H2 or earlier versions
✓ No hardware changes occurred—only the Windows update changed
✓ Multiple games now stutter that didn’t have issues before
✓ Stuttering appeared immediately after update, not gradually over time
Symptom Indicators:
✓ Borderless windowed mode stutters significantly worse than exclusive fullscreen
✓ Stuttering gets worse with Discord, OBS, browser, or GeForce overlay active
✓ Performance feels worse despite FPS counter showing similar or higher numbers
✓ Game Bar notification or capture icon appears during gameplay
✓ Micro-stutters every few seconds with consistent timing (not random)
Hardware Context:
✓ You have capable hardware (RTX 3060+, RX 6600+, or equivalent)
✓ Games show high FPS (120-240+) but still feel choppy
✓ CPU and GPU usage are normal (not maxed out at 100%)
✓ Temperatures are normal (under 80°C for CPU/GPU)
Not 25H2-specific stuttering if:
If stuttering existed before the 25H2 update: This is a general Windows 11 configuration issue or hardware problem, not a 25H2-specific conflict. Read Fix Windows 11 Stuttering in 20 Minutes for general Windows 11 troubleshooting.
If FPS is consistently low (below 60): This is a performance problem, not a frame-timing problem caused by 25H2. Read Low FPS on a High-End PC? Fix It in 15 Minutes instead.
If stuttering is random and inconsistent: Check for thermal throttling, background apps, Windows updates downloading, or antivirus scans running. 25H2 stuttering is usually consistent and reproducible.
If only one specific game stutters: This is likely a game-specific optimization issue or outdated game patch, not a Windows 25H2 problem affecting multiple games.

What Causes Windows 11 25H2 Stuttering?
KB5066835 Performance Regression (October 2025): Microsoft’s October 2025 cumulative update introduced a severe performance regression affecting all GPU brands. Some titles saw FPS drops of up to 50%. NVIDIA released emergency hotfix driver 581.94 specifically to address this. If you installed Windows updates in October-November 2025 and noticed dramatic performance drops, this is the likely cause.
Windows 11 25H2 stuttering is caused by specific feature changes Microsoft made in this update:
1. MPO (Multi-Plane Overlay) Changes – Microsoft modified MPO behavior for overlays and multi-window rendering. Games in borderless windowed mode now experience frame presentation delays when overlays (Discord, browsers, GeForce Experience) are active.
2. Game Bar Auto-Capture Expansion – Windows 11 25H2 automatically enables gameplay capture for more games without user consent. Background recording causes CPU overhead and storage write stuttering even when you never use Game Bar.
3. VBS Auto-Enable on Upgrades – Upgrading from Windows 10 to Windows 11 25H2 automatically enables Virtualization-Based Security (VBS). This security feature adds 5-15% performance overhead, causing micro-stutters and reduced 1% lows.
4. Power Throttling Algorithm Changes – 25H2 changed how Windows manages CPU and GPU power states. Even “High Performance” mode now throttles more aggressively, causing inconsistent frame delivery in some games.
5. GPU Scheduling Behavior Changes – Hardware-Accelerated GPU Scheduling works differently in 25H2. Systems with older GPU drivers experience stuttering because drivers weren’t optimized for the new scheduling behavior.
6. DirectStorage Cache Invalidation – DirectStorage implementation changed in 25H2. Games using DirectStorage experience shader compilation stuttering because cached data from previous Windows versions became incompatible.
Before downgrading Windows or buying new hardware, test the fixes below most 25H2 stuttering is completely fixable through configuration changes.
Already Know It’s 25H2 Stuttering?
If you’ve confirmed stuttering started immediately after the Windows 11 25H2 update and matches the symptoms above, skip straight to the fixes below.
Quick 30-Second Check: Confirm This Is 25H2-Related
Before changing settings, confirm your stuttering is actually 25H2-related:
Check Your Windows Version:
– Press Windows key + R
– Type: winver
– Press Enter
– Look for “Version 25H2” in the window
If you see Version 25H2 (Build 26200.x or newer): You’re on 25H2, continue below.
If you see Build 26100.x (Windows 11 24H2): Your stuttering isn’t 25H2-specific, but the same fixes in this guide still apply since 24H2 and 25H2 share the same platform. Read Fix Windows 11 Stuttering in 20 Minutes instead.
Test Basic Correlation:
– Note when stuttering started
– Check Windows Update history: Settings > Windows Update > Update history
– Look for “Feature update to Windows 11, version 25H2”
– Compare the install date to when stuttering started
If dates match (within 1-3 days): Likely 25H2-related, continue below.
If dates don’t match: May be a different issue, but test the fixes anyway.
Step 1: Disable MPO (Multi-Plane Overlay) for Borderless Gaming
Time: 5 minutes
Impact: High for borderless windowed games with overlays
MPO changes in Windows 11 25H2 are the #1 cause of stuttering in borderless windowed mode, especially when Discord, OBS, browsers, or GeForce Experience overlays are active.
How to Disable MPO (NVIDIA – Official Method)
NVIDIA provides official registry files for disabling and restoring MPO:
1. Go to NVIDIA’s official MPO support article (search “NVIDIA disable MPO”)
2. Download mpo_disable.reg
3. Double-click the file to apply
4. Restart your PC
5. Test your games in borderless windowed mode
If stuttering is fixed: MPO was the problem. Keep it disabled.
If no improvement: Restore MPO using mpo_enable.reg from the same NVIDIA article, then continue to Step 2.
How to Disable MPO (AMD – Manual Method)
AMD doesn’t provide official registry files, but the manual method works:
1. Press Windows key + R
2. Type: regedit
3. Navigate to: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\Dwm
4. Right-click in the right pane > New > DWORD (32-bit) Value
5. Name it: OverlayTestMode
6. Double-click it and set Value data to: 5
7. Click OK
8. Restart your PC
To restore MPO later: Delete the OverlayTestMode value or set it to 0.
What to Expect
Less stuttering in borderless windowed mode
Smoother gameplay with Discord overlay, browser windows, or OBS active
No more frame presentation delays when alt-tabbing
Possible slight increase in input lag in borderless mode (acceptable tradeoff for most)
Important: Disabling MPO only affects borderless windowed and windowed mode. If you play in exclusive fullscreen, MPO isn’t involved; your stuttering has a different cause.
Step 2: Disable Game Bar Auto-Capture
Time: 3 minutes
Impact: High if Game Bar was auto-recording
Windows 11 25H2 automatically enables gameplay capture for many games without asking. This background recording causes stuttering even if you never use Game Bar features.
How to Disable Game Bar Captures
1. Open Settings (Windows key + I)
2. Go to Gaming > Captures
3. Turn OFF “Record in the background while I’m playing a game”
4. Turn OFF “Record audio when I record a game”
5. Scroll down to “Recorded audio” section
6. Set all audio recording options to “Don’t record”
How to Fully Disable Game Bar (Optional)
If you never use Game Bar features:
1. Settings > Gaming > Xbox Game Bar
2. Turn OFF “Enable Xbox Game Bar”
3. Press Windows key + R
4. Type: services.msc
5. Find “Xbox Live Game Save” service
6. Right-click > Properties
7. Set Startup type to: Disabled
8. Click Stop, then OK
What to Expect
No more background recording overhead
Less CPU usage during gaming
Reduced storage write activity (helps with SSD stuttering)
No more Game Bar notification popups during gameplay
Note: Disabling Game Bar means you can’t use Windows key + G for quick screenshots or recordings. If you use these features, only disable background recording (first section) and keep Game Bar enabled.
Step 3: Clear DirectX Shader Cache and Graphics Pipeline Cache
Time: 5 minutes
Impact: High for DirectStorage games and Unreal Engine titles
Windows 11 25H2 changed DirectStorage implementation, invalidating shader caches from previous Windows versions. This causes compilation stuttering and asset loading hitches.
How to Clear DirectX Shader Cache
1. Press Windows key
2. Search: Disk Cleanup
3. Select your C: drive
4. Check “DirectX Shader Cache”
5. Click OK
How to Clear Graphics Pipeline Cache (NVIDIA)
1. Open NVIDIA Control Panel
2. Go to Manage 3D Settings
3. Click “Restore” at the bottom right
4. Click “Apply”
How to Clear Graphics Pipeline Cache (AMD)
1. Open AMD Software
2. Go to Gaming > Global Graphics
3. Click “Reset” at the bottom
4. Confirm
After Clearing Caches
Restart your PC completely
Launch your games first load may take slightly longer
Games will rebuild shaders during first gameplay session
Stuttering should reduce significantly after shaders rebuild
What to Expect
Less traversal stuttering in open-world games
Smoother performance after initial shader compilation
Reduced hitching when loading new areas
Better frame pacing in Unreal Engine games
If stuttering persists after caches rebuild (15-20 minutes of gameplay), continue to Step 4.
Step 4: Check VBS (Virtualization-Based Security) Status
Time: 4 minutes
Impact: High if you upgraded from Windows 10 to Windows 11 25H2
If you upgraded from Windows 10 directly to Windows 11 25H2, VBS may have been auto-enabled during the update. This adds significant performance overhead.
How to Check If VBS Is Enabled
1. Press Windows key + R
2. Type: msinfo32
3. Press Enter
4. Scroll down to “Virtualization-based security”
5. Check the status
If it says “Running”: VBS is enabled, continue below.
If it says “Not enabled”: VBS isn’t your problem, skip to Step 5.
How to Disable VBS (Test Only)
Important: VBS is a legitimate security feature. This is a troubleshooting test, not a permanent recommendation.
1. Search for “Core isolation”
2. Open “Core isolation details”
3. Toggle “Memory integrity” OFF
4. Restart your PC
5. Test your games
If stuttering improves significantly: VBS was causing performance issues on your system.
If no improvement: Re-enable Memory integrity and continue to Step 5.
What to Expect If VBS Was the Problem
5-15% FPS improvement in CPU-heavy games
Better 1% lows and frame pacing
Reduced micro-stutters in competitive games
Smoother performance in simulation and strategy games
Decision Point: If disabling VBS fixes your stuttering, decide whether the performance gain is worth the security tradeoff for your specific use case. This is a personal decision no universal recommendation.
Step 5: Update GPU Drivers with 25H2 Optimizations
Time: 10-15 minutes
Impact: High if running pre-25H2 drivers
GPU drivers released before Windows 11 25H2 (late 2025) don’t have optimizations for the new GPU scheduling behavior. Update to the latest drivers with 25H2-specific fixes.
How to Check Current Driver Version
NVIDIA:
1. Right-click desktop > NVIDIA Control Panel
2. Bottom left: “System Information”
3. Check “Driver version”
AMD:
1. Right-click desktop > AMD Software
2. Top right gear icon > System
3. Check “Driver Version”
How to Update to Latest Drivers
NVIDIA:
1. Go to nvidia.com/drivers
2. Select your GPU model
3. Download the latest Game Ready Driver
4. Run installer
5. Choose “Custom installation” > Check “Perform clean installation”
6. Complete installation and restart
AMD:
1. Go to amd.com/support
2. Select your GPU model
3. Download latest Adrenalin driver
4. Run installer
5. Choose “Factory Reset” option if available
6. Complete installation and restart
What to Expect After Driver Update
Better GPU scheduling compatibility with Windows 11 25H2
Reduced stuttering in borderless windowed mode
Improved frame pacing
Better overlay performance (Discord, GeForce, browsers)
Driver versions with 25H2 optimizations:
NVIDIA: 581.94 or higher (emergency hotfix for KB5066835 performance regression)
AMD: 24.12.1 or higher
If you’re already on the latest drivers and still stuttering, continue to Step 6.
Step 6: Adjust Power Management for Windows 11 25H2
Time: 5 minutes
Impact: Medium – helps with throttling-related stuttering
Windows 11 25H2 changed power management behavior. Even “High Performance” mode now throttles more aggressively than in 23H2.
How to Set Ultimate Performance Mode
Note: Ultimate Performance mode is hidden by default in Windows 11 25H2.
1. Open Command Prompt as Administrator
2. Type: powercfg -duplicatescheme e9a42b02-d5df-448d-aa00-03f14749eb61
3. Press Enter
4. Open Settings > System > Power & battery
5. Set Power mode to: “Best performance“
6. Go to Control Panel > Power Options
7. Select “Ultimate Performance” if it now appears
Alternative: High Performance Mode Settings
If Ultimate Performance doesn’t appear:
1. Control Panel > Power Options
2. Select “High performance”
3. Click “Change plan settings”
4. Click “Change advanced power settings”
5. Set these values:
– Processor power management > Minimum processor state: 100%
– Processor power management > Maximum processor state: 100%
– PCI Express > Link State Power Management: Off
– USB settings > USB selective suspend: Disabled
What to Expect
More consistent CPU clock speeds during gaming
Less frame time variation
Better 1% lows in CPU-heavy games
Slightly higher idle power consumption (acceptable tradeoff)
Step 7: Test Hardware-Accelerated GPU Scheduling Toggle
Time: 3 minutes
Impact: Medium – inconsistent across systems
Windows 11 25H2 changed how Hardware-Accelerated GPU Scheduling works. Some systems run better with it on, others with it off.
How to Test GPU Scheduling
Current State:
1. Settings > System > Display
2. Graphics > Change default graphics settings
3. Check “Hardware-accelerated GPU scheduling” status
Test Opposite State:
1. Toggle the setting to the opposite state (on → off, or off → on)
2. Restart PC
3. Test games for 15-20 minutes
4. Compare stuttering vs. previous state
Keep Whichever Works Better
If toggling improved stuttering: Keep the new setting.
If toggling made it worse: Switch back to the original setting.
If no difference: Keep it ON (Microsoft’s recommended default for 25H2).
What to Expect
This is system-dependent no universal answer
RTX 40-series and RX 7000-series typically benefit from ON
Older GPUs (GTX 16-series, RX 5000) may run better with OFF
Test both states on your specific system
Additional Fix: Disable Fullscreen Optimizations (KB5077181 Stutter)
Time: 2 minutes
Impact: High for rhythmic stuttering that appeared after February 2026 updates
Windows 11’s February 2026 update (KB5077181) introduced a new rhythmic
stuttering pattern in some games. If your stutter has a consistent rhythm rather than random hitches, this fix is worth testing.
How to Disable Fullscreen Optimizations for a Specific Game:
1. Find your game’s .exe file (or right-click shortcut > Open file location)
2. Right-click the .exe file
3. Select Properties
4. Go to Compatibility tab
5. Check “Disable fullscreen optimizations”
6. Click Apply > OK
7. Launch the game and test
What to Expect:
Elimination of rhythmic hitching introduced by KB5077181
No meaningful performance downside for most games
May slightly affect variable refresh rate behavior in some titles
When These Windows 11 25H2 Fixes Don’t Work
If you’ve tested all 7 steps and still have stuttering:
Check for pending Windows updates: Settings > Windows Update > Check for updates. Microsoft releases post-25H2 patches that fix additional stuttering issues.
Check for BIOS/firmware updates: Motherboard manufacturers release BIOS updates with Windows 11 25H2 compatibility improvements, especially for AMD X670/B650 and Intel Z790/B760 boards.
Test Safe Mode with Networking: If games run smoothly in Safe Mode, a third-party driver or background service is conflicting with 25H2. Use MSConfig to disable startup items systematically.
Consider rolling back to 24H2 or 23H2: Settings > System > Recovery > Go back. You have 10 days after updating to roll back without reinstalling. If stuttering completely disappears on 23H2, the issue is definitely 25H2-specific and may require waiting for Microsoft patches.

Frequently Asked Questions
Why does Windows 11 25H2 cause more stuttering than 23H2?
Windows 11 25H2 changed how MPO handles overlays, modified GPU scheduling behavior, expanded Game Bar auto-capture to more games, and adjusted power management algorithms. These changes improve efficiency and security but create conflicts with existing game engines and GPU drivers. Most stuttering is fixable through configuration changes it’s not a fundamental Windows 11 problem but rather an adjustment period as drivers and games optimize for the new behavior.
Should I roll back to Windows 11 23H2?
Only if you’ve tested all fixes in this guide and stuttering persists. Most 25H2 stuttering is fixable through disabling MPO, turning off Game Bar captures, clearing shader caches, and updating GPU drivers. Rolling back loses security updates and future game optimizations. Try the fixes first rollback should be the last resort, not the first move.
Is disabling VBS safe for gaming?
VBS (Virtualization-Based Security) is a legitimate security feature that protects against sophisticated attacks. Disabling it is a personal decision based on your threat model. For most home gaming systems, the security risk is minimal. For work computers, shared systems, or if you handle sensitive data, keep VBS enabled and accept the performance overhead. This is a test to identify the problem, not a universal recommendation.
Will these fixes work on Windows 11 24H2?
Windows 11 24H2 shares the same platform as 25H2. Both versions receive the same cumulative updates. If you’re on 24H2 (Build 26100.x), the same fixes in this guide apply to you.
Does Windows 11 25H2 hurt gaming performance overall?
No, not inherently. After proper configuration and driver updates, Windows 11 25H2 gaming performance is comparable to or better than 23H2. The initial stuttering issues are growing pains from new features, not fundamental limitations. Microsoft and GPU manufacturers continue releasing patches and driver updates that improve 25H2 gaming performance. Initial problems don’t define long-term performance.
Can I keep MPO disabled permanently?
Yes, disabling MPO is safe and has minimal downsides for gaming. You may notice slightly higher input lag in borderless windowed mode (1-3ms), which is imperceptible to most players. The tradeoff eliminating overlay-related stuttering—is worth it for most gamers. Exclusive fullscreen mode isn’t affected by MPO status, so competitive players using fullscreen see no difference.
Why did Game Bar start auto-recording my games?
Windows 11 25H2 expanded Game Bar’s auto-capture feature to more games without requiring user opt-in. Microsoft’s intent was to make highlight recording more accessible, but the implementation causes performance issues because background recording runs without notification. Disabling background recording in Settings > Gaming > Captures stops this behavior while keeping other Game Bar features available.
How do I know if my GPU drivers have 25H2 optimizations?
Check your driver release notes: NVIDIA GeForce drivers 581.94 and higher include the emergency hotfix for the KB5066835 performance regression. AMD Adrenalin drivers 24.12.1 and higher include 25H2 support. If you’re running older drivers, update to the latest version through NVIDIA’s or AMD’s official driver pages.

Final Takeaway
Windows 11 25H2 stuttering is usually caused by MPO changes, Game Bar auto-capture, invalidated shader caches, auto-enabled VBS, or outdated GPU drivers that don’t support the new GPU scheduling behavior. Most cases are completely fixable without rolling back the update or buying new hardware.
Start with the highest-impact fixes first: disable MPO if you play in borderless windowed mode, turn off Game Bar background recording, clear your DirectX shader cache, check VBS status if you upgraded from Windows 10, and update to the latest GPU drivers with 25H2 optimizations.
If those steps don’t resolve the stuttering, move to the linked guides above to narrow down whether the issue is Windows 11-specific, hardware-related, or game-specific. Smooth gameplay is achievable on Windows 11 25H2, it just requires the right configuration for the new features Microsoft introduced.
