Free (but last) nVidia Gelato GPU rendering

nVidia will provide the latest (and last) version of Gelato for free. This is a rendering system which utilizes your graphics adapter (but it has to be an nVidia Quadro card!).

The software was previously available in a free and non-free pro version. The pro version will not be developed anymore and has become free now.
