Dresden, Germany ([http://flightgear.org/forums/viewtopic.php?f=5&t=18851 EDDC]) and Innsbruck, Austria ([http://flightgear.org/forums/viewtopic.php?f=5&t=19625 LOWI]) have recently been populated with about 50,000 buildings derived from openstreetmap data. The buildings are textured with hi-res facade and roof images. While this certainly improves [http://img703.imageshack.us/img703/1985/fgfsscreen015.jpg visual] impression over the current random buildings, rendering a huge number of individual models in a scene is quite demanding. The FG process eats ~3GB RAM when flying in those areas, you might see a severe fps hit, and the download is ~50 MB each. However, the buildings respect LOD settings, and there's work underway to also reduce the memory footprint. | Dresden, Germany ([http://flightgear.org/forums/viewtopic.php?f=5&t=18851 EDDC]) and Innsbruck, Austria ([http://flightgear.org/forums/viewtopic.php?f=5&t=19625 LOWI]) have recently been populated with about 50,000 buildings derived from openstreetmap data.
