It is true there is some slowdown caused by the new compiz 0.9.7, in
order to eliminate tearing. But not everyone will notice it.
The slowdown is discussed in bug 930192. I hope we'll have it fixed
before 12.04.

hate to ask because Im sure you have more important stuff to work on,

Daniel,
Thank you for your excellent work! Im using your ppa in Ocelot and I cant
believe how buttery smooth my windows are moving now! The last time I remeber
seeing them so smooth was on my Maverick install. Using fglrx with HD4200.
This is kind of a noobish question but the fixes are
Correct; the fixes improve the performance of compiz in general. Not
just moving windows. It's not a noobish question but actually quite
perceptive.
The main improvement in game performance is best described by bug
861061. The fix for that is in ppa:vanvugt/unity.

Should we expect 0.9.7 to hit Precise's repository with your fixes
anytime soon?

Sorry, but publishing PPA packages for precise would unlikely be worth
the effort. I fully expect precise will have compiz 0.9.7 within a
