Do I need DirectX 9 if I have DirectX 11?
Yes it should be fine. DX11 is backwards compatible with DX9. You will never have more than 1 version of DX in Windows OS. However, just be aware that some old games do not run at all or run well in Windows 7.
Is DX9 faster than DX11?
DX11 CAN be faster then DX9/DX10, assuming you do nothing but use DX10/9 features using DX11 code [which doesn’t make much sense from a development standpoint]. Throw in Tesselation [which is VERY expensive performance wise], and you’ll see performance decreases in most all implementations.
Is DirectX 11 good for games?
We at the DirectX team designed DirectX 11 to be the best API for game developers to use in their engines. Even though we shipped DX11 a decade ago, for many games it’s still a great option. Having said that, DX12 has several advantages over DX11.

How is a device context used in Direct3D 11?
