While looking at the scene graph I saw that the .btg files are
generating a lot of leafs.
This is not new, but perhaps it is becoming worse each time the source
data resolution used to build the
tile becomes finer.
I have added a few traces in simgear's sgBinObjLoad functions, an example :

to be transformed by (and sent to) the hardware by saving 1
