I've just installed all the packages from your PPAs (both Unity and
Compiz) and I find that whilst the performance is slightly better than
it was before, it's still not as good as it was in Natty (or in the
Oneiric default version of Compiz with Unity plugin disabled). I'm using
a ATI Radeon X1250 with the radeon open source driver - the proprietary
driver doesn't support my graphics card any more.

So unless  I've made some mistakes during the installation, which is
very possible, it seems that these packages don't fix everything for me.

I haven't done any proper benchmarks but I can see two main differences:
-1 The animations seem to play properly now - by that I mean that although 
everything seems to happen in slow motion, they are not 'jerky' as they were 
before
-2 The system feels a bit more responsive, especially to keyboard input when 
typing. There is still a noticeable lag between pressing a key and the 
character appearing on screen but nowhere near as much as before I installed 
the patch
-3 Previously, I could get perfect performance (as I had in Natty) with Compiz 
with the Unity plugin disabled. Now disabling the Unity plugin doesn't help at 
all and the problems with the performance remain.

Hope this is helpful
