Vue 4 supposrts OpenGL -if you have the right graphic card. It does for me with my poor Nvidia TNT 2, 64, but some modern graphic cards seems not to be loved so much by Vue. But otherwise, you will never regret to buy Vue, because it is a great software, easy to learn and very powerful. Just see the gallery here at Renderosity:-) For more questions and any help we're always here for you:-) Guitta
