Gelato Pro 2.2 has been release as free. This is a rendering software that was developed by Nvidia. It is meant to capitalise on Nvidia Quadro graphics card for GPU-accelerated rendering. Basically, it is a high-quality hardware-accelerated renderer that sports advanced capabilities such as HDRI, Depth of field, subsurface scattering and global illumination.

Currently there are integrations of Gelato with Maya and 3D Studio Max. A Blender exporter for it is also in the works.
