I have a ATI proprietary drivers but it makes the Unity 3D very slow except 2D. Like everything works but it runs a bit slow and choppy. You could even see it when you see the loading circles on the Chromium browser. Also it shows choppiness when I have the wobbly windows turned on. Can someone help me fix?

I had same problem, but, however, in my case adjusting compiz settings didn't help a lot.
I also had ATI drivers installed. Then I noticed ATI had JUST released new ones, which are said to have much better supprot for the latest X and Unity. However, ATI released them too late, and they failed to get into Ubuntu repositories.
What I reccoment you is to uninstall the ATI driver (fglrx) Ubuntu installed for you, and get the newest one from the ATI's site: http://support.amd.com/us/gpudownload/Pages/index.aspx
In my case this provided incredible improvement of overall performance. I hope it will help you too!

When you have downloaded the driver (it should be a .run file) double-click it, choose "run in terminal" (or something similar, as I use a translated version of ubuntu), and follow the displayed instructions. And be sure to uninstall the driver you use before you begin installation! – Rafał Cieślak Apr 30 '11 at 20:16

You can remove them both by using "hardware drivers" from the System Settings, or by typing
sudo apt-get purge fglrxfrom terminal. – Rafał Cieślak Apr 30 '11 at 20:52 -

@Kevin You should ask how to install the drivers as a separate question. – Jorge Castro May 03 '11 at 21:29

Whilst this may theoretically answer the question, it would be preferable to include the essential parts of the answer here, and provide the link for reference. – Anwar Aug 02 '12 at 11:05
