How to run glxgears at full speed and not synchronized to vertical refresh?

You normally use glxgears to check performance of your graphic card but you get the same as your monitor refresh rate (60Hz = 60fps). You simply need to override a variable to not run synchronized to the vertical refresh.

To do so, simply run the following:

export vblank_mode=0
glxgears

As simple as that.
