Animation scale

I have it at 1, I like seeing the animations (and it doesn't feel like it slows my phone down that much, so...). 0.5 is too fast for me to 'appreciate' haha. But if you're truly worried about it slowing the phone down, then just turn it off.
 
I used to set it to around .5... but now I just leave it at the stock value (1). I've come to appreciate animations, to be honest... a phone with well designed, smooth running animations adds to the experience, gives it an integrated, well-designed look as everything glides into the next function. 0.5 just seems way to hectic for me... I just relax and let it flow.
