How to Reduce Input Lag in Competitive Games (2025)
How to Reduce Input Lag in Competitive Games (Simple Tweaks That Work)
Intro
In competitive gaming, milliseconds matter. Whether you’re playing Valorant, Apex Legends, or CS2, input lag — that tiny delay between pressing a key or moving your mouse and seeing it on screen — can be the difference between a win or a loss.
The good news? You don’t need expensive hardware to fix it. In this guide, we’ll show you how to reduce input lag in games using simple Windows, hardware, and in-game tweaks that actually work.
1. What Is Input Lag and Why It Happens
Input lag is the delay between your input device (keyboard, mouse, or controller) and what you see on screen. It’s caused by:
- High display latency (monitor refresh rate or response time)
- Software frame buffering (V-Sync, triple buffering)
- Driver or Windows processing delays
- Network latency in online games
Reducing these layers of delay gives you more responsive, “snappy” gameplay.
2. Enable Game Mode and High-Performance Plan in Windows
Windows 11 includes tools that help prioritize your game’s resources and reduce processing delays.
- Press Win + I → Gaming → Game Mode → Turn it ON
- Go to System → Power & Battery → Power Mode → Select “Best Performance”
This ensures Windows allocates more CPU and GPU power directly to your game.

While V-Sync prevents screen tearing, it also adds delay because frames are held back until the display is ready. To minimize input lag:
- Turn V-Sync OFF in your game’s video settings
- Disable Triple Buffering if available
- Use NVIDIA Reflex or AMD Anti-Lag+ if supported
These modern technologies reduce input lag while keeping frames stable.
4. Set Display to Native Refresh Rate
Many players unknowingly run games below their monitor’s refresh rate (e.g., 60Hz instead of 144Hz or 240Hz).
To fix it:
- Right-click desktop → Display Settings → Advanced Display
- Select your monitor → Choose the highest refresh rate available
- Ensure the same rate is set in your GPU control panel
Higher refresh rates drastically reduce display lag and make input feel more immediate.
5. Use Wired Connections for Mouse, Keyboard & Internet
Wireless peripherals and Wi-Fi add microseconds of delay — which can build up. For competitive gaming:
- Use a wired mouse and keyboard (USB over Bluetooth)
- Connect your PC or console via Ethernet instead of Wi-Fi
- Disable background downloads and updates while gaming

6. Adjust GPU Settings for Low Latency
NVIDIA and AMD GPUs have built-in settings to reduce render queue delays.
🟩 NVIDIA (Control Panel)
- Open Manage 3D Settings
- Find Low Latency Mode → Set to Ultra
- Set Power Management Mode → Prefer Maximum Performance
🟥 AMD (Radeon Settings)
- Go to Gaming → Graphics → Radeon Anti-Lag → Enable
- Enable Radeon Boost for supported titles
7. Optimize In-Game Settings for Low Latency
Certain graphics settings increase visual quality but also cause lag. To stay competitive, lower or disable:
- Motion Blur
- V-Sync
- Post-Processing Effects
- Frame Limiters (unless capped at monitor refresh)
Keep “Render Ahead Frames” or “Pre-rendered Frames” at 1 in your GPU settings.
8. Reduce Input Delay in Controllers
For controller players (console or PC), input lag often comes from polling rate or wireless interference.
- Use wired controllers whenever possible
- Disable extra vibration or light bar effects
- For Xbox controllers: update firmware via Xbox Accessories app
9. Update GPU Drivers Carefully
Sometimes new drivers introduce performance issues. Always:
- Perform a clean installation using Display Driver Uninstaller (DDU)
- Rebuild shader cache after updates
- Roll back to stable drivers if input lag increases
Conclusion
Reducing input lag in games is about balancing visual quality and responsiveness. With these tweaks — from Windows settings to GPU adjustments — you can cut delay by 30–50%, giving you faster reactions and a competitive edge.
⚙️ Pro Tip: Once optimized, use tools like NVIDIA Reflex Latency Analyzer or RivaTuner to monitor your system latency in real-time.
