Say you have a vertex buffer object containing 300 vertices, and you have 100 faces which access this vertex object, each sorted by a material ID (say, 10 different materials). If I bind the vertex object 10 different times (for the 10 different materials) during a frame, will this be a severe performance hit? Will it go and transform the vertex buffer object each of the 10 times? Or is it safe to use it like this?
