    As I'm using sprites and other 2D rendering systems, it seems moving forward I will need to develop my own solutions to rendering entities in a purely DOTS format.

    The question is, where do I actually schedule the GPU execution? There seems to me 4 ways currently:

    1. Direct Graphics static class calls. Primarily the Graphics.Draw and Render methods.
    2. Graphics.ExecuteCommandBufferAsync
    3. URP / HDRP Render Pass API.
    4. RenderPipelineManager Begin / End Camera/Context Rendering events.

    Which one should I be using?

    Wherever possible, I would recommend using the URP and HDRP APIs (e.g. URP ScriptableRenderPass), as those are likely to be the best way for the drawing to get scheduled at the desired time (e.g. opaque rendering pass). They also give you access to the ScriptableRendererContext, which makes it possible to utilize BatchRendererGroup if necessary.
