I hold down the "i" key. CPU is near 100% in J process while updating the screen. As more of the spheres fall outside the rendering region, frame refresh rate speeds up considerably. This suggests that the time is dominated by the glCallList LORENZ This also suggests that the GPU is not being used much, if at all, in that call. Fundamentally, this is a driver issue. It's possible that if J created the opengl context differently that the GPU would be used. However, other than contacting the intel and asking for help, I don't know how to find out what the important issues are here. -- Raul ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
