Sorry to tell you, but you would need to have the discrete graphics card option in there. Intel integrated graphics cards do NOT support CUDA. That is nVidia only territory. There is no "hack" to get it to work, to my knowledge, so you'd need to use CPU. And that's probably too slow. You can extrude text and do 3D work in C4D though. I think that feature is included in C4D lite.
