Hi, I'm adding precipitations in our application and I'm very surprised by the performance differences when I use different antialiasing settings.
Configuration: Core 2 duo 6400 / GeForce 7900 GTX I run the command "osgprecipitation cow.osg" No AA: 587 Hz (initial view) 2380 Hz (viewed from above) 2x: 554 Hz (initial view) 2046 Hz (viewed from above) 4x: 480 Hz (initial view) 1530 Hz (viewed from above) 8xS: 2 Hz (initial view) 440 Hz (viewed from above) The anisotropic filtering also reduce the performances. Can someone confirm these results. Why does the camera position impact the frame rate ? Is there some "things" that are not rendered when the raindrops are seen from above ? _______________________________________________ osg-users mailing list [email protected] http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
