Nothing I have done on the device feels like the software is waiting on the hardware. Everything about the iPad Pro feels like the hardware is just waiting on the software. This is great, as it means each iOS update will only make the performance on the iPad Pro that much better.
I’ve had this exact same feeling ever since purchasing the iPad Air 2 in February. The device is powerful enough to handle anything I can throw at it, but the primary limiting factor is in the software that runs on it.
