How to Fix Low Game FPS in Windows for Better Performance

Experiencing low FPS (frames per second) in your favorite games can be frustrating and ruin your gaming experience. Whether your game stutters, lags, or runs slowly, fixing low FPS can make gameplay smoother, more responsive, and more enjoyable. This guide provides you with practical, step-by-step instructions to optimize your Windows PC for better gaming performance. Before starting, ensure your system meets the game’s minimum requirements and that your Windows is up to date. Having a stable internet connection is also beneficial if your game requires online features or updates.

What You’ll Need

• Windows PC with administrative access
• Updated graphics card drivers (NVIDIA, AMD, or Intel)
• Game files and settings access
• Optional: System cleanup tools (like Disk Cleanup or CCleaner)
• Optional: Hardware monitoring tools (like MSI Afterburner or HWMonitor)

Step-by-Step

1. Update Your Graphics Drivers
   Start by ensuring your graphics card drivers are current. Visit the official NVIDIA, AMD, or Intel website, download the latest drivers compatible with your GPU, and install them following the on-screen instructions. Restart your PC afterward to apply updates.
2. Adjust In-Game Settings
   Lower graphics settings such as resolution, texture quality, shadows, and anti-aliasing. Opt for a balance between visual quality and performance. Many games have preset options like “Low” or “Performance”—use these if you want quick improvements.
3. Close Background Applications
   Press Ctrl + Shift + Esc to open Task Manager. End unnecessary processes that consume CPU, RAM, or disk resources—especially web browsers, streaming apps, or other non-essential software—so your game can utilize more system resources.
4. Optimize Windows Power Settings
   Go to Control Panel > Power Options and select the “High Performance” plan. This prevents Windows from throttling CPU performance to save energy, ensuring maximum power for gaming.
5. Disable Fullscreen Optimization
   Right-click on your game’s executable or shortcut, select Properties, navigate to the Compatibility tab, and check “Disable fullscreen optimizations.” This can reduce input lag and improve FPS in some titles.
6. Adjust Windows Graphics Settings
   Open Settings > System > Display > Graphics. Add your game if it’s not listed, then set it to “High Performance.” This prioritizes GPU resources for your game.
7. Set Priority and Affinity in Task Manager
   Launch your game, then open Task Manager. Find the game process, right-click, choose “Go to details,” right-click the process again, and set priority to “High.” You can also set affinity to allocate CPU cores specifically to the game.
8. Disable Unnecessary Visual Effects
   Navigate to System > Advanced system settings > Settings (under Performance). Choose “Adjust for best performance” or manually disable options like animations and shadows that may hinder FPS.
9. Check for Windows Updates
   Go to Settings > Update & Security > Windows Update, and install any pending updates. Keeping Windows updated ensures compatibility and performance improvements.
10. Perform Disk Cleanup and Defragmentation
    Use Disk Cleanup to remove unnecessary files. If you’re using an HDD (not SSD), defragment your disk via the Defragment and Optimize Drives tool to improve load times and overall system responsiveness.
11. Monitor Hardware Temperatures and Usage
    Use tools like HWMonitor or MSI Afterburner to check if your CPU or GPU are overheating, which can cause throttling and FPS drops. Clean dust from your PC or consider improved cooling solutions if temperatures are high.
12. Consider Hardware Upgrades
    If your system is still struggling, upgrading your GPU, adding more RAM, or switching to an SSD can significantly boost FPS and overall gaming performance.

Common Mistakes

• Ignoring driver updates — outdated drivers are a major cause of performance issues.
• Setting graphics to ultra-high without considering hardware limitations.
• Running too many background processes during gaming sessions.
• Not adjusting in-game settings for performance versus quality balance.
• Neglecting Windows updates that include performance improvements and bug fixes.
• Overlooking hardware temperatures, leading to thermal throttling.

Tips

• Regularly update your graphics drivers and Windows OS to benefit from performance improvements.
• Use game mode in Windows 10/11 (Settings > Gaming > Game Mode) to prioritize gaming performance.
• Disable unnecessary startup programs to free up system resources at launch.
• Adjust in-game resolution and settings based on your hardware capabilities for a smoother experience.
• Invest in hardware upgrades if your system consistently struggles with FPS issues.
• Use performance monitoring tools during gameplay to identify bottlenecks.

Troubleshooting

If your FPS remains low despite following these steps, consider the following troubleshooting tips:

• Verify Game Files: Use the game launcher (Steam, Epic, etc.) to verify integrity of game files. Corrupted files can cause performance issues.
• Reinstall the Game: Sometimes, reinstalling can fix underlying issues affecting performance.
• Check for Background Malware: Run a full system scan with a trusted antivirus to ensure malware isn’t affecting system resources.
• Test Hardware Stability: Use stress testing tools to check if your CPU or GPU are stable under load. Hardware failures can cause FPS drops.
• Disable Overclocking: If you have overclocked your GPU or CPU, revert to default settings to prevent instability.
• Adjust Virtual Memory: Increase your system’s virtual memory (page file) size to help with RAM shortages.
• Consult Hardware Support: If issues persist, contact hardware manufacturers or professional technicians for further diagnosis.

Frequently Asked Questions

1. Why is my game running slow even after lowering settings?

This could be due to outdated drivers, thermal throttling, background processes, or hardware limitations. Check temperatures and update drivers first.

2. How do I know if my hardware is causing low FPS?

Use monitoring tools like MSI Afterburner to check CPU and GPU usage and temperatures. High usage or overheating indicates hardware bottlenecks.

3. Will overclocking improve my FPS?

Overclocking can boost FPS but also increases heat and risk of instability. Proceed cautiously and ensure proper cooling.

4. Is it better to run games in windowed or fullscreen mode for performance?

Fullscreen mode generally offers better performance and less input lag, but some games perform well in windowed or borderless modes depending on your system.

5. How often should I update my graphics drivers?

Check for updates monthly or whenever a new game or driver update is released to ensure optimal performance and compatibility.

6. Can upgrading hardware fix low FPS issues?

Yes, upgrading components like GPU, RAM, or switching to an SSD can significantly improve game performance if your current hardware is a bottleneck.
