Power Plan: The Single Biggest Free FPS Unlock
This complete Windows 11 FPS boost guide shows you how to optimize your system for maximum frame rates. Windows 11 defaults to the Balanced power plan, which allows the OS to reduce CPU and GPU clock speeds when they are not at 100% utilization — a behavior that directly increases frame preparation time and input latency. During the idle milliseconds between rendered frames, Balanced power plan allows clocks to ramp down; when the next frame begins, the CPU must ramp back up before it can start work. This ramp-up delay adds inconsistent frame time variance that manifests as micro-stuttering even when your average FPS counter looks fine.
High Performance and Ultimate Performance plans lock CPU clocks at their maximum P-state continuously, eliminating ramp-up latency entirely. The cost is higher idle power consumption — relevant on laptops, negligible on desktop systems with adequate cooling.
1Switch to High Performance or Ultimate Performance Power Plan
How to enable:
1. Press Win + R → type powercfg.cpl → press Enter.
2. In Power Options, select High Performance.
3. If Ultimate Performance is missing: open PowerShell as Admin and run 'powercfg -duplicatescheme e9a42b02-d5df-448d-aa00-03f14749eb61'.
4. Refresh Power Options and select Ultimate Performance.
• Desktop vs Laptop: High or Ultimate Performance eliminates CPU clock ramp-up latency on desktops. On laptops, High Performance is recommended while plugged in.
On laptops, always revert to Balanced when gaming on battery. High Performance on battery can throttle to protect battery health.2Disable USB Selective Suspend
How to disable:
1. Power Options → Change plan settings → Change advanced power settings.
2. Expand USB settings → USB selective suspend setting.
3. Set to Disabled → click Apply.
• Why it matters: Prevents Windows from powering down idle USB ports, avoiding reconnection delays and polling rate drops on your mouse/keyboard.
3Set Processor Power Management to 100% Minimum
How to configure:
1. In Power Options advanced settings → Processor power management.
2. Minimum processor state: set to 100%.
3. Maximum processor state: leave at 100%.
• Impact: Keeps CPU at max P-state continuously, removing frame time variance between rendered frames.
Game Mode & Hardware-Accelerated GPU Scheduling (HAGS)
Windows 11 introduced two dedicated gaming features that affect how GPU resources are allocated and scheduled. Both are enabled by default in Windows 11, but it's worth verifying their state and understanding what they actually do — because the correct configuration depends on your hardware generation.
1Verify Game Mode Is Enabled
How to enable:
1. Open Settings → Gaming → Game Mode.
2. Toggle Game Mode to On.
• Benefits: Prioritizes CPU/GPU resources for the active game, pauses Windows Update background installs, and stabilizes frame times.
2Enable Hardware-Accelerated GPU Scheduling (HAGS)
How to enable:
1. Settings → System → Display → Graphics → Default graphics settings (or 'Change default graphics settings').
2. Hardware-accelerated GPU scheduling: On.
3. Restart your PC to apply changes.
• Supported hardware:
- Nvidia: GeForce GTX 10-series (Pascal) and newer (GTX 1060+, GTX 16-series, RTX 20/30/40-series).
- AMD: Radeon RX 6000 and RX 7000 series+ (RDNA 2/3; official support in Adrenalin drivers, limited on older RX 5000 series).
• Impact: Offloads GPU scheduling directly from CPU to the GPU scheduling processor, lowering system latency by 1–5ms in GPU-bound scenarios.
If you experience frame stuttering, driver crashes, or OBS capture glitches on older architectures (like Pascal GTX 10-series), ensure your GPU drivers are up to date or test with HAGS disabled.3Set Per-Game GPU Preference
How to set:
1. Settings → Display → Graphics → Add an app.
2. CS2 path: 'Steam\steamapps\common\Counter-Strike 2\game\bin\win64\cs2.exe'.
3. Valorant path: 'Riot Games\VALORANT\live\ShooterGame\Binaries\Win64\VALORANT-Win64-Shipping.exe'.
4. Click Options → select High performance.
Background Apps & Startup Services: Freeing CPU and RAM
Background applications consume CPU cycles, RAM bandwidth, and disk I/O that your game needs for consistent frametimes. Windows 11 launches a significant number of background processes by default, and third-party software installers frequently add startup entries that compound over time.
1Disable Startup Applications
Ctrl + Shift + Esc (Task Manager) → Startup apps tab. Sort by Status and disable non-essential items.
High-priority candidates to disable:
• OneDrive (disable auto-launch unless backing up)
• Microsoft Teams & Spotify
• Discord (launch manually when needed)
• Adobe updaters
• Nvidia GeForce Experience (if not using features)
• Non-critical manufacturer utilities
Disabling startup apps reduces boot-time memory usage by 300–800 MB and eliminates background CPU spikes.
2Disable Xbox Game Bar (If Not Using It)
How to disable:
1. Settings → Gaming → Xbox Game Bar.
2. Set 'Open Xbox Game Bar using this button on a controller' / Toggle: Off.
• Impact: Removes DirectX/Vulkan presentation hooks, freeing up 1–3ms of system latency.
Disabling Xbox Game Bar also disables the Windows + G shortcut and FPS overlay. If you rely on them, keep Game Bar enabled.3Disable Background Recording (Captures)
How to disable:
1. Settings → Gaming → Captures.
2. Record in the background while I'm playing a game: Off.
• Impact: Stops continuous disk write operations and frees NVENC/AMF encoder headroom.
4Disable Memory Integrity (Only If Certain)
How to disable:
1. Settings → Privacy & security → Windows Security → Device Security → Core isolation.
2. Toggle Memory Integrity to Off.
3. Restart PC.
• Performance gain: Reclaims 5–10% CPU overhead and 5–15 FPS in CPU-bound titles on older platforms.
Do NOT disable Memory Integrity on machines used for work, banking, or sensitive tasks due to reduced hypervisor security.
Visual Effects & Animation: Reclaiming CPU Cycles
Windows 11's visual interface — transparency effects, animations, shadows, and live thumbnails — consumes GPU and CPU resources. While modern systems handle these at negligible cost, reducing or disabling them reclaims a small but consistent amount of resources and contributes to lower and more stable frame times.
1Set Visual Effects to Best Performance
Press Win + R, type sysdm.cpl → Advanced tab → Performance → Settings → Visual Effects → Adjust for best performance.
To keep the interface readable yet fast, manually uncheck:
• Animate windows when minimizing and maximizing
• Animations in the taskbar
• Fade or slide menus into view
• Fade or slide ToolTips into view
• Fade out menu items after clicking
Keep checked:
• Show thumbnails instead of icons
• Smooth edges of screen fonts
2Disable Transparency Effects
How to disable:
1. Settings → Personalization → Colors.
2. Toggle Transparency effects to Off.
• Impact: Reduces GPU compositor rendering load on taskbar and start menu.
3Disable Widgets and News Feed
How to disable:
1. Settings → Personalization → Taskbar → Widgets: Off.
2. Settings → System → Notifications → Turn off Microsoft Start / News.
• Impact: Eliminates background WebView2 CPU/RAM consumption.
Network & DNS Settings for Competitive Gaming
Network configuration affects ping stability and packet loss in online games. While OS-level tweaks cannot overcome a fundamentally poor ISP connection, several Windows network defaults add unnecessary overhead that can be eliminated.
1Disable Nagle's Algorithm
How to disable via Registry:
1. Press Win + R → regedit → HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces.
2. Find the subkey matching your network adapter IP address.
3. Add DWORD (32-bit): TcpAckFrequency = 1.
4. Add DWORD (32-bit): TCPNoDelay = 1.
5. Restart PC.
• Impact: Removes 10–50ms TCP packet batching delay for matchmaking and server services.
This registry modification affects TCP behavior system-wide. Safe for gaming, but avoid applying to bulk data servers.2Switch to a Fast DNS Server
How to change:
1. Settings → Network & Internet → Ethernet / Wi-Fi → DNS server assignment → Edit → Manual (IPv4).
2. Cloudflare (Fastest): 1.1.1.1 / 1.0.0.1
3. Google: 8.8.8.8 / 8.8.4.4
4. Quad9: 9.9.9.9 / 149.112.112.112
3Set Network Adapter to Maximum Performance
How to configure:
1. Device Manager → Network Adapters → right-click adapter → Properties → Advanced.
2. Energy Efficient Ethernet (EEE): Disabled
3. Green Ethernet: Disabled
4. Power Saving Mode: Disabled
5. Interrupt Moderation: Disabled (reduces interrupt latency)
6. Receive/Transmit Buffers: Set to maximum
Storage & File System Tweaks for Faster Load Times
CS2 and Valorant load assets from disk during map loading and mid-game. Storage bottlenecks manifest as long initial load times, texture pop-in, and occasional mid-game hitches when assets stream from disk. These tweaks minimize OS overhead in the storage pipeline.
1Enable AHCI / NVMe Mode in BIOS
Setup steps:
1. Enter BIOS (Del / F2 during POST) → Storage Configuration.
2. Ensure SATA mode is AHCI (for SATA SSDs) or M.2 slot is NVMe mode.
3. Verify in Windows: Device Manager → Disk drives → confirm NVMe / AHCI controller.
2Disable SSD Defragmentation Schedule
Verification steps:
1. Search 'Defragment and Optimize Drives'.
2. Confirm SSD drive type is 'Solid state drive'.
3. Ensure TRIM schedule is Weekly/Monthly and remove third-party defragmenters.
3Disable Windows Search Indexing on Game Drives
How to disable:
1. File Explorer → right-click game drive → Properties.
2. Uncheck 'Allow files on this drive to have contents indexed in addition to file properties'.
3. Apply to subfolders and files.

Frequently Asked Questions
In benchmark testing, Windows 11 and Windows 10 perform nearly identically for gaming workloads on equivalent hardware and drivers. The performance difference between fresh installations of both OSes is typically within margin of error (1–3%). Where Windows 11 can underperform is in default configurations that have accumulated background services, scheduled tasks, and security features enabled over time. The tweaks in this guide address Windows 11-specific defaults (VBS/HVCI, Widgets, HAGS state) and apply equally to Windows 10 where relevant settings exist.
Yes, on supported hardware with current drivers. HAGS was introduced with significant bugs in 2020 that gave it a poor reputation, but by 2022–2023 drivers resolved most of the compatibility issues for mainstream GPUs. On an Nvidia RTX 3000/4000 series or AMD RX 6000/7000 series GPU with drivers from 2023 or later, HAGS provides consistent 1–5ms system latency reduction in GPU-bound scenarios and has no documented performance downside in gaming. The recommendation to disable HAGS is based on outdated 2020–2021 driver data.
No. Every setting in this guide is accessed through official Windows interfaces — Settings, Control Panel, Device Manager, Power Options, and Registry Editor. None of these modifications alter system files, drivers, or hardware firmware. Disabling Memory Integrity (HVCI) is the most significant security change here, but it is a standard Windows security feature toggle, not a system modification. All changes are fully reversible by restoring default values.
With caution. Community debloater scripts (like Win11Debloat or various PowerShell scripts) can be effective, but they often disable services or remove components that affect gaming in unexpected ways — including Xbox Identity Provider (required for some anti-cheat systems), Windows Audio service components, or network stack components. Manual application of specific tweaks, as shown in this guide, is safer than running automated scripts with broad defaults. If you do use a debloater, review exactly what it disables and test stability after each major change.
It depends on your baseline configuration. On a freshly installed Windows 11 system with default settings, applying the full set of tweaks in this guide typically yields a 5–15% FPS improvement in CPU-bound games (CS2, Valorant) and a 3–8% improvement in GPU-bound games (where the GPU is the bottleneck, not the CPU). The latency improvements — particularly from power plan, HAGS, polling rate consistency, and Nagle's algorithm — are more consistent than FPS gains and are noticeable in competitive gameplay regardless of your hardware tier.
Some tweaks may be reverted by major Windows feature updates. Settings to re-verify after any major update: Game Mode state, HAGS state, Power Plan selection, Visual Effects setting, and Xbox Game Bar state. Windows updates have been documented resetting these in the past. Registry tweaks (Nagle's algorithm, DNS settings) generally persist through updates. It's good practice to review your gaming configuration after any major Windows version update.
