Interface lag when not playing back.

Hello,

I was hoping you could help me find a solution to the interface lag I experience in all Adobe products.   Because I video edit more than most things in Premiere CS6 I've found the best display of what I am talking about and recorded it for you to see.   It's just easier that way.

Please notice that when I am not playing back there is considerable lag to the interface, however as soon as I start playback the lag is gone and the interface works smooth as butter.   Very strange.

Please offer some helpful advice?

Adobe CS6 MC

Win7 64

Asus Z9PE-D8

Dual Intel Xeon 2.6 Ghz 8 core

64 gig RAM

GFX: Quadro 5000

All drivers up to date
