Bug Description
Binary package hint: unity
On a relatively fresh install, Unity and/or Compiz have some very troubling performance characteristics. While the Unity dock bar on the left moves smoothly, window movement around the desktop is jerky and lags in the order of ~1+ seconds. Very noticeable.
Running 3D apps also reveals a severe impact in performance.
Several changes to system settings pertaining to vblank and vsync have been attempted, but to no avail. I'm running on a Core i5 2500k with a GeForce 560ti. This computer should slice through window compositing and even 3D surfaces like butter.
More details as I consult with others can be found here:

Performance of the 3D Unity/Compiz stack seriously needs to improve if you want to drive adoption of this desktop. These dips in performance are very frustrating and impacting my (and others') first impressions of Unity.

Thank you for your bug report, do you get the same issue in a classic GNOME session with compiz?
