------- Additional Comments From stefandoesinger@gmx.at 2006-07-07 04:23 ------- Can you attach a +d3d trace? I'd like to see in which way the vertex buffers are used by this app. I guess that is is creating a non-sysmem vertex buffer and uploads new vertices every frame.
It could be related to the card / driver too, maybe the vbo code does calls which causes performance issues with nvidia drivers. Usually vbos are a performance improvement, especially on newer cards.
