Is there a way so that when OpenGL vsyncs that it doesn''t make the call to SwapBuffers blocking (ie: wait 1/60th of a second for the monitor)?

If I understand you correctly, you need to use one of the swap control extensions. Since i do all my programming in Windows the only one I''m familar with is "WGL_EXT_swap_control". Look in the OpenGL extension registry for more info.

It depends also on driver and settings...however vsync is not so bad because you avoid flickering during swap buffer.
If you want try to remove vsync you need to use extensions...
