Hi all, I am using OSG 2.6.0 on Linux. I am currently trying to render a subgraph of my scene to texture and then use that rendering again visibly at another place in my scene. I am experiencing some performance problems I would not expect:
When using an unmodified osgprerender example on a 1680x1050 screen and moving the camera closer to the waving flag, my frame rate drops from 60fps to 30fps (I am using a v-synced setting). The GPU load seems unusually high for me with 20+ms spent on the GPU in that case. Is this a normal value? Why is the performance better when rendering the texture to frame buffer or pixel buffer (both ~12-14ms) than when rendering to frame buffer object (20+ms), which AFAIK is the standard for doing rendering to texture? Thanks for your help, Alex. _______________________________________________ osg-users mailing list [email protected] http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
