    Search for 'Disk Cleanup', select your C: drive, and check 'Temporary files', 'Recycle Bin', and 'Delivery Optimization Files' to free up space.

  • Disable Superfetch/SysMain (for SSDs) Medium impact

    Open Services (services.msc), find 'SysMain' (Superfetch), right-click, go to Properties, set 'Startup type' to 'Disabled', and click 'Stop'. This is generally not needed for SSDs and can sometimes cause issues.

  • Clear Shader Cache Medium impact

    Periodically clear the shader cache in your AMD Adrenalin software and within Warzone's settings to prevent corruption and stutters.

Recommended Call of Duty: Warzone settings

Setting Recommended value Why it matters
Render Resolution 100% Always target 100% native resolution for clarity. Use FSR 2.1 for upscaling if you need more FPS.
Upscaling / Sharpening FSR 2.1 (Performance/Balanced) Leverage AMD FidelityFX Super Resolution 2.1 to significantly boost FPS on your RX 7600 without a major visual quality hit. Start with 'Performance' or 'Balanced' mode.
Texture Resolution Normal or Low The RX 7600 has 8GB VRAM. 'Normal' is usually fine, but 'Low' can free up VRAM, reducing stutters, especially in busy areas. Monitor VRAM usage.
On-Demand Texture Streaming Off Disabling this prevents the game from downloading textures during gameplay, which can cause significant hitches and packet burst, especially on slower internet connections.
Particle Quality Low High particle quality is very demanding on both CPU and GPU. Setting it to 'Low' can provide a noticeable FPS boost during explosions and intense firefights.
Spot Cache / Sun Shadow Cache Low / Low These settings consume VRAM and can contribute to stutters if set too high, especially with 8GB VRAM. Lowering them helps maintain VRAM headroom.
Field of View (FOV) 100-110 While not a direct FPS setting, a higher FOV renders more on screen, slightly impacting performance. Find a balance that suits your playstyle and maintains good FPS.

Common mistakes to avoid

  • Running too many background applications, browsers, or streaming software simultaneously with Warzone.
  • Neglecting to update GPU drivers or using outdated Windows versions, leading to performance issues and instability.
  • Not optimizing Windows power plans, allowing the CPU and GPU to run below their full potential.
  • Ignoring in-game VRAM usage warnings, leading to texture streaming issues and stutters on the RX 7600.
  • Disabling essential Windows services without understanding their function, potentially causing system instability.

Pro tips

  • Monitor your system's CPU, GPU, and RAM usage with tools like MSI Afterburner or AMD Adrenalin Overlay while playing to identify bottlenecks.
