Unity Performance


Unity performs well on very high-powered computers, but not so well on low-powered computers.

Below are tips to make Unity blazingly fast on low-powered computers.

  1. Install the Unity Tweak Tool
  2. Search the Dash for "tweak" to start the tool.
  3. Switch off everything under the "Window Manager" section.
  4. Logout and login again.
  5. Be amazed.

Please note: You will lose certain Unity functionalities when switching off "Window Manager" functions. To restore them, simply click on the "Restore Defaults" buttons in the "Unity Tweak Tool".
