Cost of calling glBindBuffer


Does it just set an internal variable to the passed buffer or does it have to do much more?


Every GL call does slightly more, i.e. first getting a reference to the context that is current to the thread, then some error checking based on the arguments. But apart from that, glBindBuffer should have a small cost.


Is this different for index buffers? As it seems for this all you have to do is bind it.
