If you mean the new animations for opening and closing windows, they can be disabled with defaults write -g NSAutomaticWindowAnimationsEnabled -bool false.

Note that it makes the lookup popovers sometimes stay visible until windows are closed; sometimes showing them even makes applications crash.

  • defaults read NSGlobalDomain |grep -i anim

I Would recommend installing Secrets Pref Pane it gives you access to loads of hidden options in Mac OS X. you will find the "Animate Window Zooms" option under the "Finder" section.

enter image description here

  • That's basically the same as defaults write -g NSAutomaticWindowAnimationsEnabled -bool false mentioned in my answer

  • They both achieve the same thing yes, I find the prefpane is more convenient.
