It has been tested with Dresden, Germany (EDDC) and Innsbruck, Austria (LOWI). Both areas are now populated with about 50,000 buildings. Rendering this in FG is quite demanding. The FG process eats ~2.8GB RAM when flying in those areas, the download is ~50 MB each. | It has been tested with Dresden, Germany (EDDC) and Innsbruck, Austria (LOWI).

[[File:LOWI with OSM buildings from FL300.jpg|thumb|Aerial view of LOWI, with 60k OSM buildings]] | |||
Following Mathias' suggestion at FS Weekend 2013, I've now changed the code such that it merges all buildings per (osm2city) tile into one object, reducing the number of drawables from O(10k) to O(10). That indeed gives a nice speed-up. In fact, I'm overwhelmed by what's possible now -- here's a scene looking down at LOWI from FL300 showing 60k buildings. | |||
I've lost LOD and textures underway, but will fix that soon. Plain Scenery 2.0 gives 19 fps on i7 Intel HD 5000 2560x1440. With buildings framerate goes down to 14. | |||

The second scene, approaching LOWI from the east, went from 30 fps without buildings down to 20 fps. | |||

osm2city is pure python, but it depends on imposm.parser for OSM parsing. Some users report problems with imposm.parser on Windows -- YMMV. In the future, we might replace imposm.parser with a standard XML parser. | osm2city is pure python <del>, but it depends on imposm.parser for OSM parsing.
