How to Optimize Windows 11 for Gaming: Complete Step-by-Step Guide
Windows 11 is already a solid platform for gaming — but with a few system tweaks and settings adjustments, you can push your FPS higher, reduce latency, and make your PC feel more responsive without spending a cent. This guide walks you through every optimization you can safely make, from in-game performance settings to BIOS adjustments.
1. Create a Restore Point Before You Start
Before you change anything, create a restore point. This gives you a safety net in case something goes wrong.
Here’s how:
- Press Win + R → type
SystemPropertiesProtection→ hit Enter. - Under the System Protection tab, select your system drive (C:).
- Click Create, name it something like “Pre-Gaming Tweaks,” and click OK.
If you ever want to revert, you can roll back easily using this restore point.
2. Enable Game Mode and GPU Optimizations
Windows 11 includes built-in features that improve gaming performance and reduce latency.
Enable Game Mode:
- Go to Settings > Gaming > Game Mode → Turn it On.
Enable Optimizations for Windowed Games and GPU Scheduling:
- Go to Settings > Display > Graphics > Default Graphics Settings.
- Enable both Optimizations for windowed games and Hardware-accelerated GPU scheduling (HAGS).
These settings offload rendering tasks to your GPU, improving smoothness and responsiveness in most titles.
3. Turn Off Core Isolation (Memory Integrity)
This feature enhances security but slightly reduces gaming performance — usually by 2–5%.
Steps:
- Open Windows Security > Device Security > Core Isolation details.
- Toggle Memory Integrity to Off, then restart your PC.
⚠️ Keep Windows Defender or another trusted antivirus active for protection.
4. Debloat Windows 11
Preinstalled apps and background services can waste system resources. You can safely remove them using the Chris Titus Tech Utility.
Steps:
- Open PowerShell as Administrator.
- Paste this command and press Enter:
iwr -useb https://christitus.com/win | iex - Use the script’s interface to remove bloatware, disable telemetry, and tune your system for performance.
This method keeps essential Windows components intact while cleaning up what you don’t need.
5. Switch to the Ultimate Performance Power Plan
Power plans directly affect CPU frequency and power delivery.
Enable the plan:
- Open Command Prompt (Admin).
- Enter:
powercfg -duplicatescheme e9a42b02-d5df-448d-aa00-03f14749eb61 - Go to Control Panel > Power Options → Select Ultimate Performance.
Test different plans like “Balanced” and “High Performance” to see what gives the best temperature-to-performance ratio on your setup.
6. Fine-Tune GPU Settings
For Nvidia Users:
Open NVIDIA Control Panel → Manage 3D Settings, then adjust:
- OpenGL rendering GPU: Your dedicated GPU
- Shader Cache Size: 10 GB
- Vertical Sync: Off
- Power Management Mode: Prefer maximum performance
- Texture Filtering – Quality: High performance
- Low Latency Mode: On or Ultra
For AMD Users:
Open AMD Radeon Settings → Graphics:
- Texture Filtering Quality: Performance
- Surface Format Optimization: On
- Wait for Vertical Refresh: Always off
- Radeon Anti-Lag: On
- Radeon Chill / Boost: Off (unless on a laptop)
Disable overlays (like Radeon ReLive or GeForce Experience) if you don’t use them—they consume CPU and VRAM resources.
7. Adjust Windows Settings for Better Performance
System Settings:
- Disable Bluetooth if not in use.
- Turn off Dynamic Lighting in Settings > Personalization.
- Disable Share Across Devices under Settings > System > Clipboard.
- Turn off unnecessary startup apps: Settings > Apps > Startup.
Visual and Privacy Tweaks:
- Accessibility > Visual Effects: Turn off transparency and animation effects.
- Privacy & Security: Disable unwanted features like Location, Activity History, and Advertising ID.
Search and Windows Update:
- Enable Enhanced file search if you prefer faster indexing.
- Go to Windows Update > Advanced Options → disable Delivery Optimization and optional features you don’t need.
8. Optimize Advanced System Settings
Steps:
- Press Win + R, type
sysdm.cpl, and open Advanced → Performance → Settings. - Choose Adjust for best performance, then manually re-enable:
- Show thumbnails instead of icons
- Smooth edges of screen fonts
- Show window contents while dragging
These keep the system fast without making it look ugly.
9. Optional Registry Tweaks (Advanced Users Only)
Export your registry before making any changes.
Here are safe tweaks you can test:
Improve Foreground Responsiveness:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Multimedia\SystemProfile
SystemResponsiveness = 10
Disable Network Throttling:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Multimedia\SystemProfile
NetworkThrottlingIndex = FFFFFFFF
Adjust Scheduling Priority:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\PriorityControl
Win32PrioritySeparation = 26
These help prioritize games over background services and minimize network latency.
10. BIOS Tweaks for Extra FPS
Enter BIOS/UEFI by pressing Del or F2 during boot.
Recommended Settings:
- XMP / DOCP: Enables your RAM’s full rated speed.
- Above 4G Decoding + Resizable BAR: Helps modern GPUs access more VRAM efficiently.
- SMT / Hyperthreading: Enable if you have fewer than 8 cores; disable and test if you have 8+ cores.
These small changes can give measurable performance boosts in demanding titles.
11. Test and Benchmark Your Setup
After applying tweaks, always test performance.
Tools to use:
- MSI Afterburner: Monitor FPS, frame time, and temps.
- CapFrameX: Analyze stability and performance trends.
- 3DMark / Unigine Heaven / Cinebench: Compare before and after results.
If a tweak hurts stability or causes stutters, revert it using your restore point or backup registry file.
12. Quick Summary
| Category | Goal | Method |
|---|---|---|
| Restore Point | System safety | System Protection |
| Game Mode | Boost FPS | Settings > Gaming |
| Debloat | Free system resources | Chris Titus Tech Utility |
| Power Plan | Max CPU performance | Ultimate Performance |
| GPU Tweaks | Optimize rendering | Nvidia/AMD Control Panel |
| Registry | Reduce latency | Regedit |

Final Thoughts
These optimizations make Windows 11 leaner and more responsive for gaming.
Remember — no two systems react the same way. Always test your setup, note results, and tweak settings gradually.
With these steps, you can enjoy smoother gameplay, reduced stutters, and higher frame rates — all without upgrading your hardware.
