Comment 7 for bug 843383

I think this is a bug & regression
Now if it only affects me on this hardware well - too bad for me

The results of the lag are easiest seen when doing compiz actions after the performance mode has dropped down to the lowest (mode 0), moving a window is a decent test as prevviouslt outlined

This also can affect scrolling in browers, firefox in particular
Just to re note: not seen in unty-2d, gnome-shell, gnome-fallback, nor in 11.04 same hardware
Also obviously not seen when using nouveau

So I'm re-opening in case there are other laptop w/ nvidia-current users who can see the same behavior
