I am going through the first tutorial for D3D10 and have a question on the swap chain description buffer usage member. Which one should it be: DXGI_USAGE_RENDER_TARGET_OUTPUT Use the surface or resource as an output render target. DXGI_USAGE_BACK_BUFFER Use the surface or resource as a back buffer. The tutorial uses DXGI_USAGE_RENDER_TARGET_OUTPUT, but since this is a back buffer, the flag DXGI_USAGE_BACK_BUFFER seems to make sense too. So can someone explain why there are two here, and when to use one over the other.
