Re: Directx 11 and 9
DirectX is a collection of APIs that handle various multi-media tasks. Yes, DirectX 11 will continue to work when it's called upon. When you install, or run games through Steam, it will automatically upgrade, or install the required DirectX version.
Some games like Crysis 2 require a separate DX11 and texture patch, in order to take advantage of DX11.
