DX12 -> biggest business gimmick by Microsoft, bullshit i didn't bought so stayed with Windows 7 where game will run better under DX11.
HAHAHAHA sure man whatever you say.. it was co developed with microsoft and amd, because amd cards take advantage of it wayy more than nvidia's cards, then of course microsoft profits from it by making ppl use win 10 (which was FREE FOR A WHOLE YEAR), and cracked if you dont want to pay (kmspico). So your reasoning is worthless.
ALSO on win 10 you get the SAME performance on dx11, and of course you take advantage of dx12 when its available (and here comes my point: a lot of devs still into dx11.. i dont know if its for lazyness to learn dx12 ways or what but.. we have few games as of now).
And the same could be said for VULKAN which is OPEN SOURCE, and i would love even MORE for devs to use that one, which gives extraordinary results like we ve seen on DOOM.
So as you can see, i debunked every statement you made, now you are better informed, but something tells me you wont change your mind..
