Recommended Call of Duty: Warzone settings

Setting Recommended value Why it matters
Display Mode Fullscreen Exclusive Ensures the lowest input latency and highest FPS by giving Warzone full control of your display.
Render Resolution 100% (or FSR 1.0 at 80-90%) 100% for native clarity. If FPS is low, use FSR 1.0 (if available) to scale down for a performance boost on GTX 1660.
Texture Resolution Low Crucial for managing the 6GB VRAM of the GTX 1660. High textures can cause VRAM capping and stutters.
On-Demand Texture Streaming Off Prevents dynamic texture loading that can cause hitches, VRAM spikes, and inconsistent frame times.
Shadow Map Resolution Low Shadows are very demanding. Reducing their quality offers a significant FPS boost with minimal competitive disadvantage.
Particle Quality Low Reduces the complexity of particle effects (explosions, smoke), which can severely impact FPS during intense firefights.
Filmic Strength 0.00 Removes the film grain effect, improving visual clarity and reducing visual noise without performance cost.
World Motion Blur / Weapon Motion Blur Off Disabling motion blur improves clarity, makes tracking targets easier, and reduces perceived input lag.

Common mistakes to avoid

  • Running Warzone with too many background applications consuming CPU and RAM.
  • Not performing a clean installation of graphics drivers, leading to performance issues.
  • Ignoring VRAM usage, especially with a 6GB GTX 1660, by setting textures too high.
  • Playing on Wi-Fi instead of a wired Ethernet connection, causing unstable ping and packet loss.
  • Enabling V-Sync in-game, which introduces significant input lag.

Pro tips

  • Regularly clear your shader cache within Warzone's settings or by deleting the 'player' folder in `Documents\Call of Duty\players` if you experience stutters after updates.
  • Experiment with your in-game FPS cap. Setting it slightly below your monitor's refresh rate (e.g., 141 FPS for a 144Hz monitor) can improve frame pacing and reduce tearing without V-Sync.
  • Consider upgrading your RAM to 16GB (or 32GB) if you're still on 8GB, as Warzone is very RAM-intensive and can cause CPU bottlenecks with insufficient memory.
