Hi all, we have a performance problem where the draw thread seems to be the bottleneck. The target hw has 8 cores and a single GPU.
We already run cull and draw in parallel but parallelizing draw itself would also help. So I tried following setup: 2 windows 2 cameras (each on one window) threading model: CullThreadPerCameraDrawThreadPerContext In this mode, I can see that I have two cull and two draw threads and they are assigned to separate cores. However, the performance is 1/2 of my original setup. Setting OSG_SERIALIZE_DRAW_DISPATCH to ON or OFF does not make any difference. Is there anything else I have to do to get good performance from above setup (e.g. some more env. vars to set)? Or should I try something completely different? thanks, tugkan _______________________________________________ osg-users mailing list [email protected] http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
