Star Citizen is one of the only Triple-A games in development that is PC first. Good that they value their Win7, Mac and Linux gamers.
Both DirectX 12 (which has nothing in common with DirectX 11) and Vulcan originate from AMD Mantel and the work of the Frostbite devs. Vulcan is the better choice nowadays, and several Triple-A games incl Doom 2016 support Vulcan.
There is no reason to use Win10 as a gamer, all games (beside the arcardy FU3) run on Win7, even the older one that stopped working with the infamous adware & spyware that Win10 is - as of today Win10 has ads in Windows Explorer, see https://news.ycombinator.com/item?id=13903519
