I can confirm that octane will not work with the new GTX 680's just tested a couple out in my machine. Really nice performance in 3Ds Max, zero output in Octane. We will just have to wait for an Octane update.

Congratulations! Octane is a terrific product, it's become a part of my everyday workflow. I can only see myself using it more and more in the future.

I can't really shed any light on a proper solution, other than rebooting and starting the animation render again. I had the same problem two nights ago, but after a couple of system reboots, my 900 frame render finally got past frame 3.
