Hi Johny, With modern graphics hardware I would recommend using GPU.
Most of osgParticle was written back before shaders so is primarily around CPU particles. These old classes need to be kept around for backwards compatibility but I wouldn't recommend using these CPU particles systems these days. The exception in osgParticle is the PrecipitionEffect class that implements a GPU based rain/snow/sleet rendering. Robert.
