There are several reports that say that there are serious performance issues using 12.04 and nVidia 7100.

Are there any work-a-round in sight?

try open drivers, binary drivers, and unity 2d. in that order. i have an older nvidia dedicated card on my laptop that took some tweaking, but it works fine now. – RobotHumans Apr 23 '12 at 13:21
Please provide a link to these reports, also test your computer with a live usb install or seperate beta partition and then report a bug in the normal way. – Martin Owens -doctormo- Apr 23 '12 at 14:07
No problem with NVidia Quadro NVS 110M, which has an NVidia GeForce Go 7300 chip, I believe. – RobinJ Apr 23 '12 at 14:38
Right now I compine binary driver and unity 2, but its the media machine (connected to the familys TV) and neighter play channels thru webbrowser, Me-TV or xbmc work well with that configuration. – Anders Wallenquist Apr 23 '12 at 16:08…… There are several bug reports, I don't think another one will contribute something new. But reading between the lines, it may be some work-a-rounds. – Anders Wallenquist Apr 23 '12 at 16:20

Here's another bug report to add to the list:

This is how I solved the problem (found in a discussion in I installed the old nvidia-173 driver AND downgraded xserver-xorg. After this XBMC, Unity and other GPU-hungry things started to work again.

1) /etc/apt/preferences.d/10xorg

Package: xorg xserver-xorg*
Pin: release a=oneiric
Pin-Priority: 1050
# So i can find dependencies for the older driver

2) /etc/X11/xorg.conf

# New section
Section "Extensions"
Option "Composite" "Disable"

3) install nvidia-173 using synaptic or apt-get

Well... step 2 alone "fixes" the issue, but basically makes Unity 3D act like 2D, which kind of defeats the purpose of the fix. – 01es May 2 '12 at 20:26

Downgrading to 295.33 helped with my GeForce 7100. Everything works well now.

Type Ctl-Alt-F1, then:

    sudo add-apt-repository ppa:ubuntu-x-swat/x-updates
    sudo apt-get update
    sudo apt-get install nvidia-current=295.33-0ubuntu1~precise~xup1

I found this solution in this article: Unity 3d no longer works after installing 12.04
