3D compiz effects choppy and slow. How to fix?

Question

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?

Solution

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!

You can remove them both by using "hardware drivers" from the System Settings, or by typing sudo apt-get purge fglrx from terminal.

@Kevin You should ask how to install the drivers as a separate question.

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.
