    While native resolution is ideal, if you struggle to maintain high FPS, DLSS can boost frame rates without significantly increasing input lag, especially with Reflex enabled. The RTX 4070 handles DLSS very well.

  • Reduce Texture Resolution and Particle Quality Low impact

    Lowering these settings reduces VRAM usage and GPU load, which can help maintain higher, more consistent frame rates, indirectly reducing latency.

3.Windows Operating System Optimization

Configure Windows 10/11 to prioritize gaming performance, minimizing background processes and system overhead that can contribute to input lag.

  • Enable Game Mode in Windows Settings Medium impact

    Game Mode optimizes your PC for gaming by suspending background tasks and allocating system resources to your game.

  • Set Power Plan to 'High Performance' or 'Ultimate Performance' Medium impact

    Ensures your CPU and other components always run at their maximum frequency, preventing dynamic scaling that can introduce micro-stutters and latency.

  • Disable unnecessary background apps and startup programs Medium impact

    Close any applications running in the background that consume CPU, RAM, or network resources, freeing them up for Warzone.

  • Disable 'Hardware-accelerated GPU scheduling' Low impact

    While intended to improve performance, for some systems and games, this feature can introduce latency or instability. Test with it off first.

4.Monitor and Peripheral Setup

Ensure your monitor and gaming peripherals are configured optimally to deliver the fastest possible response times.

  • Set monitor refresh rate to maximum (e.g., 144Hz, 240Hz) High impact

    Higher refresh rates mean more frames per second are displayed, reducing the time between frames and thus perceived input lag.

  • Enable G-Sync/FreeSync if available and desired Medium impact

    While G-Sync/FreeSync can introduce a tiny amount of latency, it significantly reduces screen tearing and stutter, leading to a smoother, more consistent experience. Pair with a frame cap just below max refresh.

  • Set mouse polling rate to 1000Hz Medium impact

    A higher polling rate means your mouse reports its position to your PC more frequently, reducing the delay between your physical movement and the in-game cursor.

  • Ensure monitor's 'Response Time' or 'Overdrive' setting is optimized Low impact

    Adjust this setting to minimize ghosting without introducing excessive inverse ghosting. Consult your monitor's manual or online reviews for optimal settings.

5.Driver Management & Updates

Keeping your drivers updated and clean is fundamental for stable performance and minimal latency.

  • Update to the latest NVIDIA Game Ready Driver High impact

    NVIDIA frequently releases drivers with optimizations for new games and performance improvements. Always use the latest stable version.

  • Perform a 'Clean Installation' of GPU drivers Medium impact

    When installing new drivers, select the 'Custom' option and check 'Perform a clean installation' to remove old driver files that might cause conflicts or instability.

  • Update Chipset and other essential drivers Low impact

    Ensure your motherboard chipset, network, and audio drivers are up to date from your motherboard manufacturer's website for overall system stability and performance.
