Requires OpenGL 4.4 or EXT_buffer_storage Current mesa exposes GL_ARB_buffer_storage when retrieving the relevant functions returns no-ops and causes failures. Improves throughput of uploads by roughly 30%-60% and download throughput by roughly 10-30% across depending on the exact scenario and hardware.
