1.Optimize In-Game Display Settings

Proper in-game display settings are fundamental for minimizing render latency and ensuring your GPU isn't overburdened, which directly impacts input lag.

  • Set Display Mode to Fullscreen Exclusive High impact

    This mode gives the game direct control over your display, bypassing the Desktop Window Manager (DWM) and reducing render latency.

  • Disable V-Sync High impact

    V-Sync synchronizes frame rates with your monitor's refresh rate to prevent screen tearing, but it introduces significant input lag. Always disable it for competitive play.

  • Set Custom Frame Rate Limit Medium impact

    Limit your FPS to a few frames above your monitor's refresh rate (e.g., 147 FPS for a 144Hz monitor) or unlimited if your CPU isn't bottlenecking. This prevents GPU over-utilization and maintains consistent frame times.

  • Adjust Render Resolution and Upscaling (XeSS) Medium impact

    Aim for 100% Render Resolution. If you struggle to maintain high, stable FPS, enable Intel XeSS (Performance or Balanced) to boost frame rates without drastically increasing input lag.

  • Set Power Limit to Max Performance Medium impact

    Ensure your GPU is receiving maximum power. In the Intel Arc Control Panel, set the power limit or performance profile to 'Max Performance' for Warzone.

  • Disable 'Image Sharpening' or 'Scaling' (unless XeSS) Low impact

    Avoid any post-processing effects in the driver that aren't XeSS, as they can add minor latency. Keep settings like 'Image Sharpening' disabled unless you specifically need them.

3.Optimize Windows Settings for Gaming

Windows itself can introduce latency if not properly configured. Tweaking these settings ensures your system prioritizes gaming performance.

  • Enable Game Mode Medium impact

    Navigate to Windows Settings > Gaming > Game Mode and ensure it is 'On'. This optimizes your PC for gaming by prioritizing game resources.

  • Disable Hardware-accelerated GPU Scheduling (HAGS) High impact

    Go to Graphics Settings > Default graphics settings and toggle 'Hardware-accelerated GPU scheduling' to 'Off'. While it can help some systems, it often introduces latency or instability for others, especially with Intel Arc.

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

    In Control Panel > Power Options, select 'Ultimate Performance' (if available) or 'High Performance' to ensure your CPU and GPU maintain maximum clock speeds.

  • Disable Background Apps Low impact

    Go to Windows Settings > Privacy > Background apps and turn off apps you don't need running in the background while gaming.

4.Peripherals and Monitor Configuration

Your input devices and display play a critical role in the perception and actual measurement of input lag. Ensure they are optimally configured.

  • Set Monitor Refresh Rate to Max High impact

    In Windows Display Settings, ensure your monitor's refresh rate is set to its highest possible value (e.g., 144Hz, 240Hz).

  • Enable Adaptive Sync (FreeSync/G-Sync Compatible) Medium impact

    If your monitor supports FreeSync (or G-Sync Compatible) and your Intel Arc A770 supports it, enable it to eliminate tearing without the latency penalty of V-Sync.

  • Set Mouse Polling Rate to 1000Hz Medium impact

    Configure your gaming mouse to a 1000Hz polling rate in its software for the fastest possible input detection.

  • Disable Mouse Acceleration (Enhance Pointer Precision) Medium impact

    In Windows Mouse Settings > Pointer Options, uncheck 'Enhance pointer precision' for raw, consistent mouse input.

5.Hardware and BIOS Optimizations

Beyond software, certain hardware and BIOS settings can impact overall system responsiveness and input lag.

  • Enable XMP/DOCP for RAM Medium impact

    Access your motherboard's BIOS/UEFI and enable XMP (Intel) or DOCP (AMD) to ensure your RAM runs at its advertised speeds, improving overall system responsiveness.

  • Update BIOS/UEFI Low impact

    Check your motherboard manufacturer's website for the latest BIOS/UEFI updates. These can improve compatibility, stability, and sometimes performance.

  • Ensure Adequate Cooling Medium impact

    Monitor CPU and GPU temperatures. Overheating can lead to throttling, causing inconsistent frame times and perceived input lag. Ensure proper airflow and cooling.

  • Install Game on SSD Low impact

    Ensure Call of Duty: Warzone is installed on a Solid State Drive (SSD) for faster loading times and reduced in-game asset streaming hitches.

Recommended Call of Duty: Warzone settings

Setting Recommended value Why it matters
Display Mode Fullscreen Exclusive Essential for bypassing DWM and achieving the lowest possible render latency.
V-Sync Off Introduces significant input lag; disable for competitive play.
Custom Frame Rate Limit Custom (Monitor Refresh Rate + 3-5 FPS) or Unlimited Prevents GPU over-utilization and maintains consistent frame pacing, crucial for perceived responsiveness.
Upscaling / Sharpening Intel XeSS (Performance/Balanced) if needed, otherwise Off XeSS can help maintain higher, more stable FPS, which reduces input lag. If FPS is already high, Off provides native clarity.
Render Resolution 100% (or lower with XeSS) Higher render resolution increases GPU load and latency. Aim for 100% or use XeSS to render at a lower resolution and upscale.
