I suspect your bottleneck if with solving. Currently, the Cuda solver is not yet open source. The (already available) Cuda dispatcher probably won't help your performance. > -> The coins slide apart when stacked on top, as if the whole setup > was on a vibrating ground plate.

By default, Bullet should perform multiple samples (10, I think, per sim step) in the solver to compensate for this. Is your app explicitly setting this down to fewer samples for performance reasons? -Paul _______________________________________________ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
