  • Fullscreen Mode Medium impact

    Always play in "Fullscreen" display mode. Borderless or Windowed modes can introduce additional latency and resource overhead.

  • Adaptive Supersampling Low impact

    Set "Adaptive Supersampling" to "Disabled." This dynamic resolution scaling can cause inconsistent frame times and introduce latency as it adjusts.

3.Windows Operating System Optimization

Tweak Windows settings to ensure your system is fully optimized for gaming performance and responsiveness.

  • Enable Game Mode Medium impact

    Go to Windows Settings > Gaming > Game Mode and ensure "Game Mode" is turned "On." This prioritizes game processes.

  • Disable Hardware-accelerated GPU Scheduling Medium impact

    Go to Windows Settings > System > Display > Graphics > Change default graphics settings and turn "Hardware-accelerated GPU scheduling" "Off." This can sometimes introduce latency on certain systems.

  • Set Power Plan to High Performance Medium impact

    In Windows Search, type "Edit power plan" > "Power Options" and select "High performance" or "Ultimate Performance" if available.

  • Disable Background Apps Low impact

    Go to Windows Settings > Privacy > Background apps and turn off apps running in the background to free up system resources.

  • Update Windows Low impact

    Ensure your Windows operating system is fully updated to the latest version, as updates often include performance and latency improvements.

4.Monitor and Display Configuration

Properly configure your monitor settings for the lowest possible display latency.

  • Set Highest Refresh Rate High impact

    In Windows Display Settings > Advanced display settings, ensure your monitor's refresh rate is set to its maximum (e.g., 240Hz or 360Hz).

  • Enable G-SYNC (if applicable) High impact

    If you have a G-SYNC monitor, enable G-SYNC in NVIDIA Control Panel for "Fullscreen mode" and cap your FPS 3 frames below your refresh rate (e.g., 141 FPS for 144Hz) to benefit from VRR without V-Sync latency.

  • Set Monitor Response Time Medium impact

    Access your monitor's OSD (On-Screen Display) and set the "Response Time" or "Overdrive" setting to its fastest stable option without introducing excessive ghosting.

  • Use DisplayPort Low impact

    Always use a DisplayPort cable for your monitor, as it generally offers better bandwidth and features for high refresh rates compared to HDMI (especially older versions).

5.Peripheral and Driver Optimization

Ensure your input devices and system drivers are configured for maximum responsiveness.

  • Set Mouse Polling Rate High impact

    Use your mouse software to set its polling rate to 1000Hz. This ensures the fastest possible reporting of mouse movements to your PC.

  • Update GPU Drivers High impact

    Download and install the latest NVIDIA Game Ready Drivers directly from NVIDIA's website. New drivers often include latency optimizations for popular games like Apex Legends.

  • Disable Mouse Acceleration Medium impact

    In Windows Search, type "Mouse settings" > "Additional mouse options" > "Pointer Options" tab, and uncheck "Enhance pointer precision." This ensures raw input.

  • Use Wired Peripherals Low impact

    Whenever possible, use wired mice and keyboards over wireless ones to eliminate potential wireless interference and latency.

6.System Cleanup and Maintenance

Keep your system clean and free of unnecessary processes that can introduce latency.

  • Close Background Applications Medium impact

    Before launching Apex Legends, close all unnecessary applications, web browsers, and background processes to free up CPU and RAM resources.

  • Disable NVIDIA Overlay Low impact

    Open GeForce Experience, go to Settings, and disable "In-Game Overlay." While useful, it can add minor overhead and latency.
