    of SwapBuffers() and glFlush()

    Is glFlush() best called before or after SwapBuffers() or not at all? I've seen it done all three ways. Thanks!

    Neither. A SwapBuffers pretty much implies that the driver has to do an internal flush. I can't see how you could possibly do an OpenGL implementation where it would be otherwise.
