Sure, after removing the filter I was getting ~530 fps. Since fps is nonlinearly related to frame time, here's the breakdown:
530fps = ~1.89ms 360fps = ~2.78ms (sobel) 300fps = ~3.33ms (5x5 guass) So the cost of applying the slightly more expensive 5x5 filter kernel cost about 3.33ms - 1.89s = 1.44ms. For reference, 60fps = ~16.67ms (I assume you already know all of this but it may be of interest to other readers) ------------------ Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=17752#17752 _______________________________________________ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
