I was wondering if I could assume that all buffer related GPU operations such as:
are guaranteed to be completed after swap buffer is performed (i.e. frame is finished) assuming vsync is on.
I'm confused as I've come across implementations of vertex streaming techniques such as rond robin vbo which imply that a vbo could still be in use during the next frame.
What I basically want to do is stream vertices through glMapBufferRange with GL_UNSYNCHRONIZED_BIT, managing the correct ranges myself so that writes and reads never overlap. This would work very well if I could just assume synchronization and reset the stream range index at the end of the frame.
In other words, does swap buffer with vsynch guarantee synchronization?
