Your RTX 4070 is struggling to hit 144 FPS. Your friend with the same GPU gets 20% better performance. The difference? They actually optimized Windows 11 for gaming, while you’re running default settings that prioritize security over speed.
Here’s what Microsoft won’t advertise: Windows 11 ships with performance-killing features enabled by default. Some users lose up to 25% of their gaming performance to virtualization features they don’t even know exist.
Your Current Windows 11 Gaming Performance
The Hidden Performance Killers in Windows 11
Windows 11 wasn’t designed exclusively for gaming. Microsoft balanced performance with security, productivity, and compatibility. For gamers, this means several features actively reduce your FPS while providing benefits you might never use.
The biggest culprit? Virtualization-Based Security (VBS) and Memory Integrity. These features can cost you anywhere from 5% to 25% of your gaming performance, depending on the game and your hardware. Yet most users don’t even know they exist.
Default Windows 11 Settings Impact
How each feature affects your gaming performance
| Feature | Default State | Performance Impact | What It Does |
|---|---|---|---|
| VBS & Memory Integrity | Enabled | -5% to -25% FPS | Protects kernel from malware using virtualization |
| Game Mode | Disabled | Missing latency reduction | Suspends DWM compositor for lower input lag |
| GPU Scheduling (HAGS) | Disabled | +1GB VRAM usage | Offloads scheduling to GPU hardware |
| Power Plan | Balanced | CPU throttling | Reduces clock speeds to save power |
| Background Services | 100+ Running | -2% to -5% FPS | Various system services consuming resources |
| Nagle’s Algorithm | Enabled | +5-15ms latency | Bundles TCP packets, adding delay |
Priority Optimizations
Not all optimizations are equal. Some provide massive gains with minimal risk, while others offer marginal improvements but could cause instability. Here’s your prioritized action plan:
Disable VBS & Memory Integrity
The single biggest performance boost. Disabling virtualization-based security features can reclaim 5-25% of lost FPS, especially in CPU-bound games.
Enable Game Mode & Optimizations
Modern Game Mode eliminates compositor latency in windowed games. Combined with windowed optimizations, provides exclusive fullscreen performance without the hassle.
Configure Power & GPU Settings
High Performance power plan prevents CPU throttling. HAGS reduces CPU overhead but increases VRAM usage. Critical for consistent frame times.
Network Optimizations
Disabling Nagle’s Algorithm can reduce online gaming latency by 5-15ms. Only affects TCP-based games, but makes a noticeable difference in responsiveness.
Service & Registry Tweaks
Disabling unnecessary services and tweaking scheduler priorities provides marginal gains. Only for dedicated gaming rigs managed by advanced users.
DirectStorage Setup
Dramatically reduces loading times in supported games. Requires NVMe SSD and game developer implementation. Currently limited but growing support.
Step 1: Check and Disable VBS (The Big One)
Virtualization-Based Security is enabled by default on all new Windows 11 installations and new PCs. However, it’s usually NOT enabled if you upgraded from Windows 10. This single feature can cost you up to 25% of your gaming performance.
Check Your VBS Status
Takes 30 seconds to verify if you’re affected
- Press Windows key and type “System Information”
- Open the System Information app
- In the System Summary, scroll down to find “Virtualization-based security”

Frequently Asked Questions
Is Windows 11 worse for gaming than Windows 10?
Not necessarily. Windows 11 has better gaming features like DirectStorage and improved Game Mode, but it enables security features by default that can reduce performance by 5-25%. After proper optimization (especially disabling VBS), Windows 11 can match or exceed Windows 10 performance.
What is VBS and should I disable it for gaming?
Virtualization-Based Security (VBS) protects your kernel from malware using hardware virtualization. It’s enabled by default on new Windows 11 installations and can reduce gaming performance by 5-25%. For dedicated gaming PCs that don’t handle sensitive data, disabling it provides significant FPS gains. Keep it enabled on work or general-use computers.
Does Game Mode actually work in Windows 11?
Yes, Game Mode in Windows 11 is completely different from the Windows 10 version. It now suspends the Desktop Window Manager compositor for borderless windowed games, eliminating a full frame of input lag. This gives you exclusive fullscreen performance without the alt-tab hassles. Always enable it.
Should I enable Hardware-Accelerated GPU Scheduling?
HAGS provides small performance gains (1-2%) but increases VRAM usage by up to 1GB. Enable it if you have 10GB+ VRAM or need DLSS 3 (which requires it). Disable it if you have 8GB or less VRAM and experience stuttering in demanding games.
What’s DirectStorage and do I need it?
DirectStorage is a new API that dramatically reduces game loading times by bypassing CPU bottlenecks and using GPU decompression. You need an NVMe SSD and a DirectX 12 GPU, but the game must also support it. Currently limited to a few titles but growing. It can reduce loading from 10 seconds to under 2 seconds.
Will disabling services break my PC?
Disabling the services mentioned (Print Spooler, Windows Search, etc.) won’t break Windows but will remove their functionality. Only disable services on a dedicated gaming PC where you don’t need printing, search, or remote access. Never do this on a work or general-use computer.
Do I need 32GB RAM for gaming in 2025?
No, 16GB remains sufficient for 99% of games. The extra 16GB will sit unused. Instead, focus on fast RAM (DDR5-6000+) in dual-channel configuration. Only consider 32GB if you stream while gaming or run heavy background applications.
Should I disable the page file?
Never disable the page file. It’s a critical safety net when RAM fills up. Disabling it causes crashes and instability with no performance benefit. Windows manages it efficiently by default. Just ensure it’s on your fastest drive (usually your OS NVMe SSD).
How much performance can I gain from these optimizations?
Total gains vary by system and game. Disabling VBS alone provides 5-25% improvement. All optimizations combined typically yield: 10-15% average FPS increase across all games, 20-30% in CPU-intensive games, and significantly reduced input lag. The biggest gains come from VBS removal and proper power management.
Are these optimizations safe?
Yes, when done correctly. The main trade-off is security (disabling VBS) versus performance. All settings can be reverted. Create a system restore point before making changes. Only apply advanced registry tweaks if you’re comfortable with that level of modification. Start with basic optimizations first.
