title: Rigidbody2D AddTorque slow after upgrading to Unity 5
body: <p>So my game was working fine with Unity 4.6, but when I imported it into Unity 5, all the Rigidbody2Ds are moving at about a fifth of the rotational velocity they were before when using rigidbody2D.AddTorque().</p>
  
  <p>I can't find any official info about it changing. Any clues?</p>
  
  <p>Thank you!</p>
