  • Enable Game Mode Medium impact

    Go to Windows Settings > Gaming > Game Mode and ensure it's turned 'On'. This optimizes your PC for gaming by prioritizing game processes.

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

    For some systems, especially with newer GPUs, HAGS can introduce stuttering. Navigate to Graphics Settings > Change default graphics settings and toggle 'Hardware-accelerated GPU scheduling' to 'Off'. Test performance after this change.

  • Set Power Plan to High Performance Medium impact

    Open Control Panel > Power Options and select 'High Performance' or 'Ultimate Performance' (if available). This prevents your CPU and GPU from downclocking during gameplay.

  • Disable Fullscreen Optimizations Low impact

    Locate the Warzone executable (e.g., `cod.exe`), right-click > Properties > Compatibility tab, and check 'Disable fullscreen optimizations'. This can improve performance and reduce input lag.

5.Manage VRAM Usage Effectively

The Intel Arc A770 typically comes with 8GB or 16GB of VRAM. For 8GB variants, Warzone's high VRAM demands can quickly lead to stuttering if not managed properly.

    Ensure all unnecessary background applications, especially web browsers, Discord overlays, and streaming software, are closed before launching Warzone to free up VRAM and system RAM.

  • Avoid High-Resolution Texture Packs High impact

    Do not install or use any optional high-resolution texture packs for Warzone. These will quickly exceed the A770's 8GB VRAM capacity and guarantee stuttering.

6.Network Optimization for Stuttering

Packet burst and high latency spikes can manifest as severe stuttering in Warzone, even if your local FPS is high. Optimizing your network can mitigate these issues.

  • Use Wired Ethernet Connection High impact

    Always prefer a wired Ethernet connection over Wi-Fi. Ethernet provides a more stable connection with lower latency and less packet loss, reducing network-related stutters.

  • Close Bandwidth-Hogging Apps Medium impact
