I'm always impressed how people can demand support for there purpose. I sometimes have the feeling some forget that blender is an opensource project. If I think it should go in my prefered direction, than I would sit down and write a patch for it. TY for bringing us cycles and all the new features for free. If it is important then I would think I would be able to go to the store and buy myself a cuda based card for under 100 EUR or start programing. My 2 cents. Johannes
