I have the same issue.  Lenovo T400 laptop with ATI graphics (Radeon Mobility HD 3400)

Happens in training mode.  Never played a regular game, nor would I with this handicap.  I'm glad I played one game on 1.1 yesterday before upgrading, so I could see it how its supposed to be!

The status bar claims an FPS of 3.  Now the motion looks a lot smoother than that, but on average with the stuttering it could very well come out to about 3 a second...
