Search-after-search I can’t find a past post I really need right now.
A long time ago someone did some tests on the best ways to update vertex buffers and he shared his results, but when I try the few key words I remember (which I won’t list here in order not to pass on a possibly mistaken key word to others) I just get results of people asking questions. I even searched replies for a link to the post for which I am searching and nothing.
So the guy benchmarked at least 3 ways to update vertex buffers.
He did client arrays and VBO’s with DYNAMIC_DRAW and different updating strategies.
One of the strategies was orphaning.
It was about 2 years ago.
My kingdom for anyone who can find that post. It may have been OpenGL ES 2.0.
