    Hi
    Can anyone tell me if GPU instancing is enabled by default when you choose 'Metal' in Player settings?

    And should you disable 'Dynamic Batching' for GPU instancing to take effect?

    You need to enable GPU Instancing in each material as well.

    One of my learnings: If you use mobile shaders, such as "Mobile/Diffuse", these do not support GPU Instancing in their shadow/depth passes.

    It's best to use a Profiler to measure different DynamicBatching/GpuInstancing/etc setups and draw your conclusions from there. At least this yielded the best and most surprising results for me.

    Thanks.
    It seems it doesn’t work with Static objects as well.
