See if double buffering applies here or if it is relevant anymore

Can be applied to other stages of rendering, but I don't thing I care for now http://gameprogrammingpatterns.com/double-buffer.html. Also for the rendering, the double buffering is used by default with GLFW http://www.glfw.org/docs/latest/quick.html. Btw the vsync is the period of processing between the swap of the front and back buffer.

I was wrong, http://ogldev.atspace.co.uk/www/tutorial28/tutorial28.html, the double buffering applies to the transform feedback, since "OpenGL enforces a general limitation that the same resource cannot be bound for both input and output in the same draw call. This means that if we want to update the particles in a vertex buffer we actually need two transform feedback buffers and toggle between them."
