I'm not surprised in the least. If RT really is the future -- it does looks awesome in action, so I hope it turns out to be more than just a curiosity. Given NVIDIA's push, it might be?
That said, it's still a bit early for that. For $1200, dropping below 60fps at only 1080p is pretty weak. That's the early adopter tax along with the "our only competition is Pascal" tax.
