Hi Jasper, Adding lots of objects in any one frame can easily become a bottleneck unless you are very careful about it. I wouldn't expect the push_back on a DrawElementsUInt to be the primary bottleneck. Make sure you do all your benchmarking in release mode as this makes a huge difference.
As to what is your best route forward will depend entirely on what you are actually trying to do in your application, so perhaps you can explain at a high level what these geometries represent and why that have to be introduced on mass on particular frames. Perhaps then others will be able to recommend what the best course of action is to take. Robert. 2009/3/26 Jesper D.
