Hi Alex, Draw time is composed of the Draw dispatch (yellow bar) and the Draw GPU (orange bar). The Draw dispatch is the OSG's CPU overhead in sending all the OpenGL tokens and data into the OpenGL fifo. The Draw GPU is the time it takes to render the frame down on the GPU, it's value is determined by an OpenGL extension, but this extension doesn't provide an absolute timing so the position on the on screen stats is just an estimate that the OSG makes.
