I am unsure on how to set my vertex buffer sizes. Since I use them in a dynamic manner, I create one vertex buffer for each "material" (buffer format) using d3dpool_default, so the system comes up with system memory if I specify too large buffers according the docu. I know there are some general rules around, like 128k or so. But is there a more specific way, e.g. by reading gpu caps? Or would it make sense to create many vertex buffers of same format and fill/use the least busiest or so? - thomas
