This bug also affects me, and I can confirm the exact same symptoms with
12.10, latest compiz and unity. I'm using the nvidia-current package
(304.48). I'd love to help contribute system configs/logs/etc or
anything else that might help, though apport-collect won't let me submit
to this bug.

Swapping speed settings appears to only work some of the time. When a
game is running, the desktop effects become incredibly slugging (5-10fps
range), but the game will continue at an uninterrupted framerate.

Off what Mr. Spilsbury said, I tried setting the nVidia drivers to
"prefer maximum performance" and the desktop is 100% silky smooth. When
left on the default of adaptive the sluggishness returns. Not sure if
that's significant. The only effect that runs smoothly on adaptive is
the alt-tab switcher
Games are running *GREAT* at the moment. It's only desktop effects that
are the problem. I'm going to keep using 12.10 now since games run even
better than on Unity2D in 12.04, but the sluggish desktop effects
continue to persist.

An odd observation, performance on some minor effects, like window
expansion in the alt-tab switcher (where it blows up the icon into the
animated window preview) runs very smoothly all the time. Window expo
will sometimes be smooth and other time run very poorly; the same
applies to the workspace
(Apologies for the broken up posts.) The workaround of turning off
vsync, detection of refresh rate, and setting the refresh rate of compiz
to 120+ no longer has any visible effect.

Unredirect fullscreen windows fixes the issue for fullscreen
applications. However, somewhat sluggish desktop performance persists,
however I have yet to reproduce uneven screen redraws in windowed games
that I can see in the Unigine Heaven demo.

I just installed the latest daily of the beta, and the problem persists
just as before on 12.04. The desktop performance with the latest updates
has improved things back to the point of being equal to 12.04.

Thanks very much for that heads up. I'll try again as soon as I can, but
since my laptop with nVidia graphics is also my main work computer it
may be awhile before I have another good opportunity to test a full
install of 12.10. =(

I gave 12.10 with the latest compiz available from the updater a try,
though I do not know the exact version number. Everything on the system
ran very slowly even after installing any version of the nvidia driver
package (current/current-updates/current-experimental). I know it's an
early beta, but
I'd like to again echo namelezz on the refresh rate settings. I think
the most annoying is the slight stuttering that can occur at what should
be very playable framerates. Nothing new to add, just confirming the
same behavior, though I'm down to just my 660m and could not test on the
460.

I have this issue in a GeForce 460 and a 660M, my experience on both
machines matches namelezz *exatly*.
