How to Optimize Windows for Gaming and Performance

A well-optimized Windows system can significantly improve gaming performance, reduce lag, and ensure a smoother overall experience. Whether you’re playing competitive shooters that require high FPS or immersive open-world games, making a few key adjustments to Windows settings can enhance responsiveness and stability. In this guide, we’ll walk through the best ways to optimize Windows for gaming and overall performance.

1. Keep Windows and Drivers Updated

Keeping your operating system and drivers up to date ensures that you get the latest performance improvements and bug fixes.

Update Windows

  1. Open Settings (Win + I) and go to Windows Update.
  2. Click Check for updates and install any available updates.
  3. Restart your PC if necessary.

Update Graphics Drivers

For NVIDIA users:

  1. Open GeForce Experience or download the latest driver from the NVIDIA website.
  2. Install the latest Game Ready Driver.

For AMD users:

  1. Open AMD Adrenalin Software or download drivers from the AMD website.
  2. Check for updates and install the latest driver.

For Intel integrated graphics:

  1. Use Intel Driver & Support Assistant to update drivers.

Tip: Always enable “Clean Installation” when updating GPU drivers to avoid conflicts with old versions.

2. Enable Game Mode in Windows

Windows includes a built-in Game Mode that prioritizes gaming performance by reducing background tasks.

  1. Open Settings (Win + I) and go to Gaming > Game Mode.
  2. Toggle Game Mode to On.

Tip: This setting prevents Windows from running updates and background tasks while gaming.

3. Disable Unnecessary Background Apps

Too many background apps consume system resources, reducing gaming performance.

  1. Open Settings > Apps > Startup Apps.
  2. Disable any apps you don’t need running at startup.
  3. Open Task Manager (Ctrl + Shift + Esc) and check the Processes tab.
  4. End unnecessary tasks like OneDrive, Cortana, and Microsoft Teams if not in use.

Tip: Avoid closing essential system processes, as this can cause instability.

4. Adjust Power Settings for Maximum Performance

By default, Windows uses a balanced power plan that limits performance to save energy. Switching to a high-performance plan can boost gaming performance.

  1. Open Control Panel > Power Options.
  2. Select High Performance or Ultimate Performance (if available).

Tip: Laptops may experience increased battery drain when using High-Performance mode.

5. Optimize Windows Graphics Settings

Enable Hardware-Accelerated GPU Scheduling

  1. Open Settings > System > Display.
  2. Scroll down and click Graphics Settings.
  3. Enable Hardware-Accelerated GPU Scheduling and restart your PC.

Set Games to High Performance

  1. In Graphics Settings, click Browse and add your game’s .exe file.
  2. Click Options and select High Performance.

Tip: This ensures Windows prioritizes your GPU when running games.

6. Adjust Visual Effects for Better FPS

Windows has various visual effects that can impact performance. Disabling unnecessary animations can improve FPS.

  1. Open Settings > System > About.
  2. Click Advanced system settings (on the right side).
  3. Under Performance, click Settings.
  4. Select Adjust for best performance or manually disable options like:
    • Animate windows when minimizing and maximizing
    • Show shadows under windows
    • Show thumbnails instead of icons

Tip: If you prefer a balanced look, keep “Smooth edges of screen fonts” enabled for better readability.

7. Free Up Disk Space and Optimize Storage

Having enough free space on your SSD or HDD helps Windows run more efficiently.

Use Storage Sense to Clear Unnecessary Files

  1. Open Settings > System > Storage.
  2. Turn on Storage Sense to automatically delete temporary files.
  3. Click Cleanup recommendations to manually free up space.

Manually Delete Old Files and Unused Programs

  1. Open Settings > Apps > Installed Apps.
  2. Uninstall apps you no longer use.

Defragment HDDs (Do Not Defragment SSDs)

  1. Open Defragment and Optimize Drives.
  2. Select your HDD and click Optimize.

Tip: If you use an SSD, enable TRIM instead of defragmentation for better performance.

8. Disable Fullscreen Optimizations for Games

Some games perform better when Fullscreen Optimizations are disabled.

  1. Right-click your game’s .exe file and select Properties.
  2. Go to the Compatibility tab.
  3. Check Disable fullscreen optimizations.
  4. Click Apply and OK.

Tip: Some games require this setting enabled for proper performance—test both options to see what works best.

9. Adjust Virtual Memory (Pagefile) for Stability

If you have limited RAM, increasing virtual memory (pagefile size) can improve performance.

  1. Open Control Panel > System > Advanced system settings.
  2. Under Performance, click Settings.
  3. Go to the Advanced tab and click Change under Virtual Memory.
  4. Select Custom size and set:
    • Initial size: 1.5 times your RAM (e.g., 8GB RAM = 12,000MB).
    • Maximum size: 3 times your RAM (e.g., 8GB RAM = 24,000MB).
  5. Click Set > OK > Restart your PC.

Tip: If you have 16GB+ RAM, Windows can manage pagefile size automatically.

10. Disable Xbox Game Bar and Background Recording

Windows includes Xbox Game Bar for screen recording, but it can reduce performance.

  1. Open Settings > Gaming > Xbox Game Bar.
  2. Turn Game Bar off.
  3. Go to Captures and turn off Background Recording.

Tip: Use third-party software like OBS Studio for better recording performance.

11. Use an SSD for Faster Load Times

Installing Windows and games on an SSD (Solid State Drive) drastically improves load times.

  • NVMe SSDs are the fastest and ideal for gaming.
  • SATA SSDs are cheaper but still much faster than HDDs.
  • HDDs should only be used for storing large files, not for running games.

Tip: Move your most-played games to an NVMe SSD for the best performance.

12. Monitor System Performance and Temperatures

Use monitoring tools to check for bottlenecks and overheating.

  • MSI Afterburner: Monitor GPU usage and FPS.
  • HWMonitor: Check CPU and GPU temperatures.
  • Task Manager (Ctrl + Shift + Esc): Identify resource-hungry programs.

Tip: Keep CPU temps under 85°C and GPU temps under 80°C for optimal performance.

Final Thoughts

Optimizing Windows for gaming ensures a smoother experience with better FPS, faster load times, and improved system stability. By adjusting power settings, disabling unnecessary features, and ensuring your PC runs on an SSD, you can maximize gaming performance. Whether you’re a casual player or a competitive gamer, these optimizations will help you get the most out of your system.
