Create different presentations and compare memory & CPU consumption and created buffers between them.
At least these should be incuded:
- one layer
- two layers
- one layer + one subpresentation with one layer
- one layer + one subpresentation with two layers
- one layer + two subpresentations with one layer each
Content should be minimal and comparable in each one (i.e. same number of shaders needed, same number of textures if any, and so on).
