Panda3D benchmark for 2d graphics

Thanks for your suggestion, @serega-kkz. It seems that I’ve found the answer on the forums:

Performance issue

While a GeForce 7800 GS can easily handle 100,000 polygons, it needs to have all of those polygons in one batch. That means they all have to be in the same node for maximum performance. When you have multiple nodes, Panda has to send each node to the graphics hardware as a separate batch of polygons (because the nodes might move independently, or have different state changes on them). Modern graphics hardware hasn’t made any improvements recently in handling large numbers of batches, just in …

It looks for me that panda3D switches textures, blendmodes, etc (I am not a graphics programmer, so I don’t really know) for every node, doesn’t matter if it uses the same texture or not, and sends them individually to the render pipeline.
