Reply #1 - Apr 13th, 2009, 3:55pm   OpenGL renders with the GPU, but I think Processing still does it's own matrix transformations so that will be slower. The biggest bottleneck though is generally sending the data to render to the card itself, so using display lists and instancing can speed up your rendering quite a bit.
