To that end, this extension introduces two new buffer object features: non-serialized buffer modification and explicit sub-range flushing for mapped buffer objects. OpenGL requires that commands occur in a FIFO manner meaning that any changes to buffer objects either block until the data has been processed by the OpenGL pipeline or else create extra copies to avoid such a block. By providing a method to asynchronously modify buffer object data, an application is then able to manage the synchronization points themselves and modify ranges of data contained by a buffer object even though OpenGL might still be using other parts of it. This extension also provides a method for explicitly flushing ranges of a mapped buffer object so OpenGL does not have to assume that the entire range may have been modified. Affects ARB_vertex_buffer_object, ARB_pixel_buffer_object and OpenGL 1.5 Buffer Objects.
