Getting away from DirectX/OpenGL for a moment, does anyone have experience with Nvidia's Optix realtime raycasting?

I have used it to create simple tests and it seemed to perform OK at low resolution, eg 1024x768 on some average hardware (GTX 560 Ti & Intel i7 Bloomfield 2.9 Ghz).

But I wonder how it performs in real world applications? Youtube has dozens of tech demo's but almost nothing in the way of real applications using the library.

It would be nice to know I am not wasting my time before I invest heaps of it coding the CUDA programs and a scene graph and managing GPU paging and all the other related parts. All that is necessary as Optix is just a raycasting library only, it is not a complete scene management solution like Nvidia's SceniX which I do not wish to use for various reasons.

Any experiences people can share about Optix would be helpful.
