Scroll down to the bottom, hit "Animation Overrides", from there, turn every single option all the way down, and go back a menu. (Slow factor of .60 I find looks best)
Then go up to "Folders" select "Allow Nested Folders". Now to make everything else fast.
Go back a menu, select "Icon Animations" and then go to Folder Open and Folder close and use these settings:
Mass: 1.00
Stiffness: 600
Damping: 100
Thats all you really need to change for the folders and app opening to be fast.
There is some more you can do within the "Icon Animations" option.
For "Unlock", use the same settings as above, your phone will unlock faster.
Also NEVER go to the "Notification Center" option and turn the gravity down. Your notification center will never stop 'bouncing' and you'll have to restart your phone.
Is there a setting to turn off the parallax effect, but keep the animations? I have the animations set the way you have them and it's a nice set up.
I'm on a 4S and what I have notices about animations is that I you turn on increased contrast in the settings app the animations are smooth as butter and not jerky. Especially message bubbles and the card switcher.
