Hello,

 I have a basic understanding of using system memory versus using  GPU memory,  which entails using Direct3D to create and manage surfaces.

One thing I am not clear on, and wonder if someone at Intel could clarify, is the tradeoffs of using Direct 3D 9 vs Direct 3D 11 with the Intel Media SDK.

Are there any reasons to use the Direct 3D 9 support other than backward compatibility?

Or, if I had to choose just one or the other to support for my application, which would be recommended?, and why?

Thank you very much,

Cameron
