I currently have a dynamic buffer, which holds data like instances information. Which method should I use to populate my ID3D10Buffer: Map(), or UpdateSubresource()?

Dynamic buffers are always filled with Map/Unmap. UpdateSubresource is used for default resources.

if your data is laid exactly the way the resource stores it, use ID3D10Device::UpdateSubresource, otherwise, use a Map method.

What do you mean by laid exactly the way the resource stores it?

I do not know :D
I make a copy-paste from Direct3D10 documentation.

I can't understand the phrase, but i thought it was a my problem for bad english.
