I see Kiro's guess and raise you an anecdote. I just turned animations off on my Android device, and instantly it feels faster and more responsive.
replyMaybe software programs got faster with our faster CPUs but all the animations just made everything feel slow.
Yes! It feels faster and more responsive now because it is faster and more responsive now. Your device is taking less time to do the same work.
replyMost people with that opinion keep using apps and devices with animations, but thinking it would be better without them. Very few actually torture themselves like that in practice.
replyFor me, animations are the torture, and I am most productive on machines that aren't artificially hobbled with animations one can't turn off.
replyYour experiences are not universal.
