Unity - Manual: Draw Call Batching

Built-in batching support in Unity has significant benefit over simply combining geometry in the modeling tool (or using the CombineChildren script from the Standard Assets package). In Unity 5.0, there is only one build of the index buffer on start and then a draw call is submitted for each sub mesh of that big mesh for each visible sub mesh.

Jan 13, 2020  Instead of drawing one object 10 times, we draw 10 objects once. That's the power of batching. The main requirement to batch draw calls is to get the objects to use the same drawing properties (material). When that happens, Unity can then merge the different meshes into a single chunk that uses the common material.

DrawCallBatching - Unity Manual

For each Renderer in the batch, Unity updates the offset into the Vertex Buffer, and then submits a new draw call. When measuring the cost of the Graphics Device calls, the slowest part of rendering a Component is the set-up of the Material state. Submitting draw calls at different offsets into a shared Vertex Buffer is very fast by comparison ...

Mar 05, 2012  Each draw call has a cost that is composed by two parts : -a "fixed" cost that you pay always. -a "variable" cost that depends on what this draw call contains ( vertices, textures etc ). If you create many independent moving game Objects that do not batch with Unity dynamic batching ( as in your case ), you pay the "fixed" cost many times.

Why are my batches (draw calls) so high? What does ... - Unity

A draw call is a call to the graphics API to draw objects (e.g draw a triangle), while a batch is a group of draw calls to be drawn together. Batching objects to be drawn together, minimizes the state changes needed to draw each object inside the batch. This is turn leads to improved performance by reducing the CPU cost of rendering the objects.

Back in the day, if you had two different meshes which used this same material, you'd get two draw calls because you were rendering two separate meshes.
