It's really difficult to draw conclusions from DX12 benchmarks at the moment. The problem is that DX12 shifts most of the responsibility for architecture-specific optimizations (and avoiding pathological cases) from the driver to the application. So although you could draw the conclusion that Nvidia are struggling with DX12 due to their Total Warhammer performance, it's just as easily explained by Nvidias veteran DX11 driver team being better at tuning for Nvidia hardware than a game studio who partnered with AMD during development.
