No. Don't have te be rooted. Go to settings, go to 'more' and then tick 'about phone'. Scroll to 'build number' and tick it 7 times. (It's not a joke)
When you ticked it 7 times you see a toast notification that says 'developer options enabled'. Go back to 'more' and you'll see an extra option called developer options. Tick and enable it by ticking the button in te top right of your screen. Once you enabled it, scroll down untill you see three options (windows animation scale, animation scale transition and transition duration) and all of them are set to 1x. Change them to off
