[QUOTE="koniosis, post: 9260, member: 11134"] Locking Vertex buffers is a real performance hit, it's probably faster to just create a new vertex buffer. How much locking are you doing? Essential you will loose any performance beneift of using the GPUs RAM when you are locking and unlocking buffers since it has to drag the data out of the GPU across the AGP bus, down the pipeline to the RAM so you can work on it and then send the whole lot back once you are finished. Why are you locking buffers? [/QUOTE]
