In Chapter 12's Adding Occluders to a complex scene example, in the 2010 version of the beginners guide of OSG, there's an occluder node which occludes 100000 randomly generated quads. The fps shown in the book is 40fps, when the 100000 'massive quads' are fully occluded and 11.57fps when not occluded.
On my system, the fps is 0.5fps when fully occluded and 1.01fps when not occluded. I have 2GB RAM, an Intel core 2 duo CPU, 2.53GHz and an NVidia GeForce GT 430 graphics card. No other applications were open at the time I ran the program. Not even Visual Studio Intellisense. Tried running the program on a system without a graphics card, and the quads didn't even render (but this is secondary. Main problem is what caused such a slow reaction on my card-equipped system). Is it a known issue among OSG users that some cards don't support OpenGL well enough? Because I saw a forum post where a person said "I think that the nVidia Quadro FX 5600 doesn't have as good OpenGL support as the "consumer" GPU cards" Here: http://www.flightgear.org/forums/viewtopic.php?f=11&t=7182 ------------------ Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=48294#48294 _______________________________________________ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
