--- Comment #10 from Stefan Dösinger stefandoesinger@gmx.at 2011-08-13 15:45:55 CDT --- I think very few native games use GL_ARB_map_buffer_range and use dynamic buffers heavily. The extension is fairly new, and most (open source) Linux games are based on the Quake 3 engine. A native app that uses this extension is the Unigine Heaven benchmark. I don't know how much it uses dynamic buffers, but from the amount of animated geometry it displays it might be a fair amount(or they have very good vertex and geometry shaders for animation)
