Confirmed. Had it in 12.04, continues on 12.10. Same card:

Title:
3D performance is very bad
Status in “xserver-xorg-video-intel” package in Ubuntu:
Confirmed
Bug description:
I'm using a couple of computers based on Intel DQ35JO board, which has
a GMA graphics chip:
$ lspci | grep VGA
00:02.0 VGA compatible controller: Intel Corporation 82Q35 Express Integrated
Graphics Controller (rev 02)
Running any sort of 3D graphics is incredibly slow, for example:
$ glxgears -fullscreen
Running synchronized to the vertical refresh. The framerate should be
approximately the same as the monitor refresh rate.
51 frames in 5.1 seconds = 10.010 FPS
which is rather good comparing to the behavior of glxgears without
fullscreen and maximized (showing the window borders and panels) which
is aroudn 5 FPS.
This is the same for both Unity 2D, standard 3D Unity (in which also
just moving windows around is painful) and KDE (in which everything is
ever slower which makes KDE practically unusable).
I've had the same behavior since I installed Ubuntu 11.10, and its the
same now with the 12.04 alpha.

I have two identical machines running 12.04 - one is using the
standard Ubuntu (with KDE installed as an option) and the other is
installed with Kubuntu. When I run glxgears on the Kubuntu machine,
its not running in synchronized mode and the fullscreen framerate is
reported around 50 FPS, though the movement is almost as choppy as in
the Ubuntu machine (so I don't understand what is going on). In the
Kubuntu machine, KDE can't do OpenGL desktop effects at all - I get
errors when I try to enable that, though glxgears does work.
A slightly older machine (running chipset 82801H - ICH8 family) works
fine.
