This is what I'm experiencing with compiz - 1:0.9.8.0-0ubuntu1:
out of the box - ghosting square and lag (with and without activated Vsync in
game)
Force full screen redraws (buffer swap) on repaint - no square but the lag
remains
unredirect fullscreen windows - perfect
I also tested when
That's enough for now thanks. This bug needs a fresh pair of eyes to
decide what to do next.

Sorry for the confusion.
The bug appeared after upgrading (fresh installation) from 11.10 to
12.04 and is still present in 12.10. While this bug is about the
performance regression (lack of responsiveness, uneven frame rate), bug
1012401 is about the ghosting rectangle. I've experienced the
OK, let's ignore bug 1012401 because it's a separate bug and unlikely to
have a direct causal link to this one.
Now, you say the nvidia powermizer issue was new in 12.10. So either:
(a) It's not a relevant detail because this bug was against 12.04; or
(b) Powermizer is the issue and it
it's (a)
and I'm experiencing the lag and the square artifact even after updating
to compiz - 1:0.9.8.0-0ubuntu1

On bug 901097 it says Add option to use glXSwapBuffers on every frame.
Is this similar to the option in CompizConfig: Workarounds-Force full
screen redraws (buffer swap) on repaint? If I enable this, the square
artifact disappears, but the lag remains. Only the option unredirect
fullscreen
Yes, the two features are similar. However the resolution to bug 901097
is much more efficient, and hopefully faster. So after you have that
fix, you definitely want to make sure Workarounds-Force full screen
redraws (buffer swap) on repaint is turned off.

Thank you Daniel, this is exactly what I'm experiencing. I've done
further testing and I found out, that the performance regression going
from 12.04 to 12.10, is due to the nVidia PowerMizer locking the card at
the Performance Level 1.

I've just freshly installed Ubuntu 12.10 again. I didn't add any PPA's
and I'm testing with default settings since I've also created a new
user. The performance in 12.10 got much worse in comparison with 12.04.
Playing Oilrush in 12.04 I get 30FPS while in 12.10 I get barely over
10FPS. I still
With ProjectM visualizations I get further performance drop with 12.10
as well.

This is a compiz bug since it appears with compiz even if the unity
plugin is deactivated. With Unity2D now dropped in 12.10, the only
workaround is to temporary unredirect fullscreen windows when starting a
game. (thank you Daniel for the hint)

The bug is very much present in 12.10 and now that Ubuntu dropped
Unity2D in 12.10 there is no sane way for me to play any games.

I think this should be solved by bug 988079, so will make it a duplicate
of that. A fix is coming in Unity 5.16.
If performance is still inadequate then consider using the unredirect
fullscreen windows
Yeah, the issue affects me. Gtx295 here, and the performance issues are
interesting, as it does not appear to impact the frames per second, but
the game definitely lags.
The issue doesn't happen with gnome shell, or unity2d.
