About this,I have two ideas.
First, Whether there is a methon which can send data from gpu to cpu asynchronously? I search this in internet,but get nothing.
Second,I do something to my character mesh directly in gpu,but how can I do this? Vertex shader? Vertex factory? Mesh shader?

Try to Asynchronous data transfer from GPU to CPU. Minimize data transfer, Use Memory mapping. Try to Modifying character mesh directly on the GPU and trying to do Vertex Shade, Geomerty Shade.
