Call of Duty: Warzone Best Settings Guide RTX 4090 (2026)

Configure your core display and graphics settings within Warzone to prioritize performance and competitive visibility while leveraging the RTX 4090's capabilities.

• Set Display Mode to Fullscreen Exclusive High impact

  This minimizes input lag and ensures your GPU is fully dedicated to the game, preventing background processes from interfering.

• Match Display Resolution to Monitor Native Medium impact

  Always use your monitor's native resolution (e.g., 2560x1440 or 3840x2160) for the sharpest image. The RTX 4090 handles high resolutions with ease.

• Enable NVIDIA DLSS (Performance/Balanced) High impact

  Utilize DLSS on 'Performance' or 'Balanced' mode to gain significant FPS without noticeable visual degradation, especially at 1440p or 4K.

• Set Refresh Rate to Max Monitor Value High impact

  Ensure your in-game refresh rate matches your monitor's maximum refresh rate (e.g., 144Hz, 240Hz, 360Hz) for the smoothest visuals.

• Disable V-Sync and NVIDIA Reflex Low Latency (On+Boost) High impact

  V-Sync introduces input lag. Disable it. Enable NVIDIA Reflex Low Latency to 'On+Boost' to minimize system latency, crucial for competitive play.

Adjust visual quality settings to ensure maximum visibility of enemies and minimal distractions, while maintaining high frame rates.

• Set Texture Resolution to High/Very High Low impact

  With 24GB VRAM on the RTX 4090, you can easily run high texture quality for better visual clarity without performance impact.

• Reduce Particle Quality to Low Medium impact

  Lowering particle quality reduces visual clutter from explosions and smoke, improving enemy visibility during chaotic engagements.

• Disable On-Demand Texture Streaming Medium impact

  This feature can cause stutters and VRAM spikes. With the RTX 4090's VRAM, local textures are sufficient and more stable.

• Set Shadow Map Resolution to Low High impact

  Shadows are a major FPS hog. Low settings provide enough shadow detail for competitive play without impacting performance.

• Disable World Motion Blur & Weapon Motion Blur High impact

  Motion blur obscures vision during movement and aiming. Disabling it provides a clearer, sharper image, essential for tracking targets.

Fine-tune your NVIDIA driver settings to ensure your RTX 4090 is performing optimally for Warzone.

• Set Power Management Mode to 'Prefer maximum performance' Medium impact

  This ensures your GPU maintains its boost clocks, preventing downclocking that can lead to stutters or lower FPS.

• Enable Low Latency Mode to 'Ultra' High impact

  This setting further reduces input lag by submitting frames just-in-time for the GPU to process, complementing NVIDIA Reflex.

• Set Texture Filtering - Quality to 'High performance' Low impact

  Prioritizes performance over minute visual fidelity in texture filtering, offering a slight FPS boost without significant visual loss.

• Disable Vertical Sync (globally) Medium impact

  Ensure V-Sync is off in the NVIDIA Control Panel to prevent it from overriding in-game settings and introducing latency.

Optimize your operating system to reduce background interference and dedicate more resources to Warzone.

• Disable Game Bar and Game Mode (Windows) Medium impact

  While Game Mode can sometimes help, it often causes issues. Disable Game Bar overlays to prevent resource conflicts.

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

  Ensures your CPU and other components run at their maximum potential, preventing throttling during intense gameplay.

• Close Unnecessary Background Applications High impact

  Browser tabs, streaming apps, and other software consume CPU, RAM, and network bandwidth. Close them before playing.

• Update Graphics Drivers Regularly High impact

  Always keep your NVIDIA drivers updated to the latest Game Ready version for optimal performance and bug fixes in Warzone.

Minimize network and input lag to ensure your actions are registered instantly and you have a stable connection.

• Use a Wired Ethernet Connection High impact

  Wi-Fi introduces latency and instability. A wired connection provides the most reliable and fastest network performance.

• Disable VPNs or Proxy Servers Medium impact

  Unless necessary for specific reasons, VPNs add routing overhead and latency. Play without them for best ping.

• Set Polling Rate for Mouse to 1000Hz Low impact

  A 1000Hz polling rate ensures your mouse input is reported to the PC 1000 times per second, minimizing input delay.
