Hi Renato, Potentially you could covert the imagery in the database to OpenGL compressed format to reduce the memory size. osgconv utility can be used to covert a loaded database to compressed using:
osgconv --compressed originaldatabase.originalextension newdatabase.osgb You can also write your own compressors to pre-process the data, have a look at the osgconv sources to see how it does it.
