Umm, I want to test an experiment. I see that qgis draws the geometries (LineStrings or Polygons) in independent calls (painter-drawPolyline or painter-drawPolygon() calls). I have experience using GDI++ as renderer and it is very faster joining n-geometries in one geometry-path and then flush

Hi! I have implemented the improvement of rendering in a new ad-hoc featureIterator with the possibility that each vector-provider implements its own method of pre-simplification. The performance is the same as the first version I developed (~3x faster :-)). It also implements the simplification

Hello Vincent! For now, it is not configurable, automatically applies to all vector layer to be painted. I think that the userneed not configure this, of course, if dev-community suggests, will be as you say! :-) Is it configurable in the interface for each layer independantly ? It should
