    Incrementally increase the 'Core Clock' by +50MHz, test stability in Warzone, and repeat until you find the maximum stable value (usually +100-150MHz for GTX 1660).

  • Increase Memory Clock Medium impact

    After stabilizing the core clock, incrementally increase 'Memory Clock' by +100MHz, testing after each step (usually +300-600MHz for GTX 1660).

  • Monitor Temperatures & Stability Low impact

    Always monitor GPU temperatures and test stability with benchmarks and extended Warzone gameplay to avoid crashes.

Recommended Call of Duty: Warzone settings

Setting Recommended value Why it matters
Render Resolution 100% (with FSR/NIS scaling) Rendering at native resolution with an upscaler like FSR 1.0 or NVIDIA Image Scaling (NIS) provides a significant FPS boost by rendering at a lower internal resolution while maintaining visual clarity.
Texture Resolution Normal The GTX 1660's 6GB VRAM is a bottleneck. 'Normal' textures offer a good balance without exceeding VRAM capacity and causing stutters.
Texture Streaming Quality Low Reduces the quality of streamed textures, directly impacting VRAM usage and preventing hitches associated with texture loading.
Particle Quality Low Particle effects (explosions, smoke) are very GPU-intensive. Lowering this significantly improves FPS during chaotic moments.
Shadow Map Resolution Low Shadows are extremely demanding. Setting this to 'Low' provides a substantial FPS boost with minimal competitive disadvantage.
On-Demand Texture Streaming Off Disabling this prevents background texture downloads that can consume bandwidth, VRAM, and cause micro-stutters.
VRAM Target 60-70% Manually setting the VRAM target lower ensures the game leaves enough VRAM for the OS and other applications, preventing VRAM capping issues on a 6GB card.

Common mistakes to avoid

  • Running Warzone with 'On-Demand Texture Streaming' enabled, leading to VRAM overloads and stutters.
  • Setting 'Texture Resolution' too high for a 6GB GPU, causing constant VRAM swapping and performance drops.
  • Ignoring driver updates, missing out on crucial performance optimizations from NVIDIA.
  • Not setting Windows power plan to 'High Performance', preventing the GPU from consistently boosting.
