dForce Lion won't render with GPU

Bought the new lion model from AM. Great model!  Purchased the dForce addition, too. Unfortunately, every time I try to render a scene with the dForce lion, my render goes to CPU. No matter what I try. Restart Studio? No go. Make the render the size of a postage stamp? No go. Remove everything from the scene except the lion? No go. The catalyzer version of the exact same lion is rendering fine, but...no dForce. I figure I must be doing something wrong, so I thought I'd ask here.

Windows 10, GTX 1060 6G Studio 4.12

    Check the log file and see how much geometry and texture memory is being used. My guess would be that the Dforce hair geometry is heavier than the LAMH/Catalyzer and that's what's pushing it off the GPU.

    If I'm reading it right, not even remotely close to using up the 6 gigs my card has. :(

    Maybe I'm reading it wrong...

    No, that looks okay. Do you have GPU-Z or a similar tool to check how much of your GPU RAM is being used?

    I do! It says 3% is being used, right before it switches to CPU.
