I have a strange behaviour i don't really understand.
Using the shape file attached to this topic.
If I display it using drape method, the GPU is very more solicitated when it is very zoomed in (like for example zoom in france polygon until there are boundaries visible) than when it is very zoom out (full globe view). I would expect the opposite as very less triangles need to be drawn when zoomed in.
The differences are from 3 to 11 ms for GPU time. Any ideas about what is causing this behaviour?
Note also that the map technique has also this issue but very very less important (from 3 to 4 ms).
Note that, It makes me think of a not efficient culling so i tried to remove the geometry merges in order to have a splited geometry which should make possible to completly cull some polygons. But without improvements so far...
