To render thousands of identical meshes in a single draw call, use GPU instancing techniques like DrawMeshInstanced or DrawMeshInstancedIndirect to significantly minimize CPU overhead and reduce draw calls.

Use GPU instancing when rendering dense scenes containing many repetitive elements like forests, crowds, or particle effects, as it solves performance bottlenecks by grouping identical meshes into one draw call.

Manage per-instance data for instanced meshes using MaterialPropertyBlock and ComputeBuffer, which allow you to efficiently pass unique attributes like position and color to each instance without creating separate materials.

DrawMeshInstanced and DrawMeshInstancedIndirect are both GPU instancing techniques for rendering identical meshes, but indirect rendering leverages ComputeBuffer to determine instance count on the GPU, further minimizing CPU overhead.

Yes, GPU instancing works for static meshes sharing the same material and mesh, combining them into a single draw call to optimize frame rates and reduce the CPU overhead required for large numbers of similar objects.
