Its updating the vertex coordinates, then reuploading the mesh to the GFX card, i think.. its the reuploading that makeas it slow, hence why i beleive an "updatemesh" command could be useful.
Of course, thats the only reason i can see it being slow- if thats not how its being done, thenm someone of higher knowledge help us out here? :)
