I am currently running Windows 7 with a i7 and GTX 1070. What would DX12 do for me in terms of Civ? I get that it improves graphical performance, but will I even notice it with a GTX 1070? Already running on highest settings, but now I am curious to what DX12 would do for me, especially considering I don't want to upgrade to Windows 10. Thanks for anyone who can provide some insight.
