--- Comment #4 from Anders Dahlberg <dahlberg at lysator.liu.se> ---
Some additional observations using (latest or 3.2) master with patch above.

One steady state is reached at 20.00 fps or 50.00 ms average frame duration.
One example is just outside Hierarch Square. 
But all locations I've tried have one (a lot of really) of these positions in
close proximity.

Another steady state is seen at exactly 15.00 or 66.67 ms average frame
duration. In the middle of Hierarch Square.

A third steady state is in the menus, exactly 60.00 FPS.

Moving between the steady states the frame rate fluctuates a lot.
But stopping to move and then slowly moving/changing viewpoint towards
higher/lower FPS is it easy to reach an equilibrium position where the FPS is
either a rock solid 15.00 or 20.00 fps. All (?) other fps values fluctuate over
time but when 15.00 or 20.00 is found you can stand there forever in exact
synchronization.
