Does ID3DXMesh cache SetStreamSource/SetIndices calls with DrawSubset?

Just that: If I were to take a ID3DXMesh and call DrawSubset on it ten times, would SetStreamSource and SetIndicies be called ten times or only on the first time?

It will be called ten times. DrawSubset doesn't attempt to do any smart optimizations.


Right. So much for common sense. ;)

DrawSubset is provided for convenience, it is recommended to do the drawing yourself if you're worried about performance, because you know your usage scenarios and can optimize for them.

Okay, thanks. I've been thinking recently about how my meshes are drawn, and was wondering how high-performance DrawSubset was.
