Windows is a powerful operating system, but it’s not automatically tuned for gaming out of the box. Background services, visual effects, unnecessary apps, and system settings can all slow down your PC, waste resources, and reduce your frame rates.
This guide will show you how to optimize Windows for better gaming and overall performance—whether you’re on a new PC build or upgrading an older system.
1. Enable Game Mode
Game Mode helps prioritize resources for gaming and minimizes interruptions.
How to enable:
- Go to Settings > Gaming > Game Mode
- Toggle Game Mode ON
This prevents Windows from installing updates or running background scans while gaming.
2. Disable Background Apps
Background apps consume CPU, RAM, and disk resources—often silently.
Steps:
- Open Settings > Privacy > Background apps
- Disable apps you don’t use
- Alternatively, go to Startup Apps and disable non-essential ones
Tip: Use Task Manager > Startup tab to prevent unnecessary apps from launching at boot.
3. Use High Performance Power Plan
Windows typically defaults to a balanced power plan.
How to switch:
- Go to Control Panel > Power Options
- Choose High Performance (or Ultimate Performance if available)
- Prevents CPU from throttling down to save power
This is crucial for gaming laptops and desktops with aggressive power-saving defaults.
4. Update Your GPU Drivers Regularly
Outdated GPU drivers are a major cause of stuttering, crashing, and underperformance.
Get latest drivers:
- NVIDIA: GeForce Experience
- AMD: Adrenalin Software
- Always opt for Game Ready Drivers or WHQL-certified versions
5. Adjust Visual Effects for Performance
Windows has many animations and effects that look nice—but drain resources.
Turn them off:
- Press Windows + R, type
sysdm.cpl, hit Enter - Under Advanced > Performance > Settings, choose:
- Adjust for best performance or
- Manually disable: Animate windows, Fade menus, Show shadows, etc.
6. Turn Off Xbox Game Bar and DVR
The Xbox Game Bar uses background resources and can interfere with full-screen games.
Disable it:
- Settings > Gaming > Xbox Game Bar → Turn it OFF
- Settings > Gaming > Captures → Disable background recording
Use alternative recording software like OBS Studio for streaming or capturing.
7. Keep Windows Updated
While automatic updates can be annoying, security and performance patches are important.
To update manually:
- Go to Settings > Windows Update
- Install the latest updates and restart your PC
- Schedule updates during non-gaming hours
8. Optimize Storage and Free Up Space
Running low on storage slows down your system, especially if your SSD is nearly full.
Use built-in tools:
- Go to Settings > Storage > Storage Sense
- Enable automatic cleanup
- Remove temporary files, downloads, and Windows.old if you’re not rolling back
Also, defragment your HDD (not SSD) regularly via Defragment and Optimize Drives.
9. Disable Full-Screen Optimizations (Per Game)
Some games perform better without full-screen optimizations enabled.
How to disable:
- Right-click game .exe > Properties > Compatibility tab
- Check Disable Full-screen optimizations
- Click Apply
10. Disable Unnecessary Services and Visual Overlays
Turn off overlays and services that add latency or compete for GPU usage.
Examples to disable:
- Discord overlay
- Steam overlay
- NVIDIA GeForce Experience overlay (Alt + Z)
You can usually toggle these off in the settings of each app.
11. Keep Your System Clean
Regularly run tools like:
- CCleaner (for cache/temp files)
- Malwarebytes (to detect hidden threats)
- Windows Security (built-in antivirus)
Also, use MSI Afterburner or HWiNFO to monitor thermals and avoid thermal throttling.
12. Overclock for Extra Performance (Optional)
If your PC has adequate cooling:
- Use MSI Afterburner for GPU tuning
- Use Intel XTU or Ryzen Master for CPU tweaking
- Test performance increases using benchmarks (3DMark, Cinebench)
Always monitor temperatures and stress test after changes.
13. Disable V-Sync (If Not Using G-Sync/FreeSync)
V-Sync can limit FPS and cause input lag.
Instead:
- Enable G-Sync or FreeSync if your monitor supports it
- Otherwise, cap FPS via in-game settings or GPU software (RTSS)
14. Optimize In-Game Settings
No amount of OS tweaking replaces optimized in-game graphics.
Prioritize:
- Texture quality
- Shadow and post-processing effects
- Resolution scaling and DLSS/FSR (if supported)
Tweak these based on your hardware and personal preference for visuals vs. frame rate.
