"fg cvs with osg 2007-04-10 dated" versus "fg cvs plib 2007-04-10 dated" Openscenegraphe is cvs 2007-04-10 Plib is the last (old) stable version 1.8.4 I did run FG plib version with 3D clouds, shadow aircraft and object scenery. FG --geometry 1800x1450 32bpp Same scenery database , same flightplan, same aircraft i get 11 fps to 37 fps with osg 35 to 89 fps with plib graphic card Nvidia 7800GS 512 Mo Fedora Core 5 -- Gérard ------------------------------------------------------------------------- This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.
