The core of the problem lies in the distinction between hardware and software rendering.

A (or Render Graph Node) is a discrete unit of work within this structure. It encapsulates a specific state—a draw call, a compute dispatch, or a resource transition. Engines use these nodes to manage dependencies. For example, a "Shadow Map" node must be executed before the "Lighting" node.
view.setLayerType(View.LAYER_TYPE_SOFTWARE, null)
It is not identical. Software renderers lack entire feature sets, including geometry shaders, compute shaders, and crucially, high-level scene graph acceleration.
