If some animations are smooth and it's only dragging windows that is a
problem then bug 773861 is probably a more appropriate place to look.
This bug is about ALL animations stuttering, which is a bug in the fglrx
implementation of "Sync To VBlank". So if you still have issues with
"Sync To Vblank

I have initially submitted this fix for lp:compiz to hopefully get it
into oneiric. If accepted then I'll happily propose it for natty-updates
too.

Revisiting this fix today... I discovered a similar (but different) slow
down when I switched to Intel graphics this week. So I'm updating the
fix for this bug to also address the framerate problem I found on Intel,
which really affects all graphics chips.

I'm only fixing the exact problem described in the Bug Description. So
the fix will only work for you if the workaround described at the top
works for you.
Of course, if the workaround works for you then you could always have
kept Unity 3D. Just turn off Sync To VBlank in CompizConfig Settings
Man
@vanvugt awesome, thanks for looking into this!
Is it safe to come back over to Unity 3d now then? :)

Title:
Compiz's "Sync to Vblank" makes display stutter/slow with some driver
@Aleksander: My proposed fix is a general compiz change, so yes it might
improve Vsync behaviour for Nvidia too.
Always remember to enable sync to vblank in your driver control panel
too. For ATI Catalyst it's called Tear Free Desktop.

Hmm, since the trigger for this bug is the behaviour of fglrx and it
could definitely be improved, best to leave the door open.
** Changed in: fglrx-installer (Ubuntu)
Status: Invalid => Confirmed

Title:

After I had switched from ATI I found that the problem also occurs with
some NVidia cards. Initially everything is alright but after couple of
hours (NVidia 9600GT) the same strange thing is happening. Perhaps it's
some kind of general Compiz issue?
