Confirmed on an Nvidia GeForce 210. Mir clients are not throttled to
vsync. This is most obvious in the simple mir_demo_client_egltriangle:

formats
Using pixel format #3
libEGL warning: unsupported platform (null)

Bug description:
I installed Ubuntu 13.10 (yesterday) in order to test Xmir and Mir natively
(examples-clients). Xmirg worked flawlessly. The only "problem" was the
duplicate mouse cursor(s).
But I noticed an abnormally high FPS in some clients demo when I tested Mir
natively per these instructions
http://unity.ubuntu.com/mir/using_mir_on_pc.html
I recorded the test case using external camera. Apologies for the quality
but you will see the values.

I attached an apport.log just for more info if are needed.
I'm not a technical guy and I filled this report prompted by @duflu in IRC
#ubuntu-mir
You can read the mini conversation here.

This test had the same results either if X only was running in VT7 (Video)
or Xmir.
I hope I helped... in something.
