Is there a optimal value for the BackBufferCount member in D3DPRESENT_PARAMETERS when creating a back buffer chain? Most people use 1 and if I use more it makes no speed difference (at least for the simple things I''m doing). Is this dependant on something like video drivers or SwapEffect used? thx

A single backbuffer is the "standard" for number of backbuffers. However, you can have two backbuffers (triple buffering) which, although it takes up more vid-card mem, provides an overall "smoother" looking program. Adding another buffer will not, however, make things speedier, you can count on that.

However, for most purposes, a single backbuffer is all you should use.
