Hi there. You don`t know what version of directX, you video card supports ? for example : DirectX 9, DirectX 10 or DirectX 11 ? and you need to know if your video card supports DirectX 11 or DirectX 11.1 right ? Well, the easy way is to look at manufacturer website but if you want, you can download this and you can see directx version supported for any video card.
How to check Directx Version
First, run the software and scroll down to dirextX
Then DirectX Video
Then look at : DirectX Hardware Support (DirectX v.11.0 in our case)
If, instead of DirectX 11 is DirectX 10 or DirectX 9, all games that require DirectX 11 Only will not work on your System and you need to upgrade your Video Card !!
Video Games like : Call of Duty Ghosts or Watch Dogs require DirectX 11 Only !
