Well 2x is a joke from beggining unless the software was fucked on Xone and Ryse can't be done with a fucked software...
About DX12 it obvious that it will improve performance of the CPU use in games... MS says in best cases (theses hypothetical) 50% in multi-core utilization... but overall you will see some 10% to 20% improvement in real games... this is a huge improvement with optimizations.
BTW the guy tha said that it will doubles the performance could have made a bad code from start and after optimizations and bug fix... plus DX12... ended with double performance in his tests.
