Zitat von »"MSDN"«

When calling SetStreamSource, the stride is normally required to be equal to the vertex size. However, there are times when you may want to draw multiple instances of the same or similar geometry (such as when using instancing to draw). For this case, use a zero stride to tell the runtime not to increment the vertex buffer offset (ie: use the same vertex data for all instances). For more information about instancing, see Efficiently Drawing Multiple Instances of Geometry (Direct3D 9).
