Physics engine update rate and display rate

[zharuViz]

Jeff, it is that in our experiment the ball moves really fast. I think I need physics engine to update fast to allow accurate collision detection.

Is the issue that the ball goes through the paddle? If that's the case you could make the collide shape thicker on the paddle. If you need to record the collision at a precision higher than the framerate I don't think that's possible.
