Apple doing an optimization focused update with iOS 12 is a breath of fresh air.
My iPad Pro 9.7" (one version old, came before the 10.5") drops frames in iOS 11's full screen blur transition animations. Before iOS 11 it was fine, but either the iOS team didn't test animations on anything but their brand new hardware, or they tested and didn't care if it ran smoothly.
Having one of the OS's most frequent animations choke on anything but the brand newest GPU in the $650+ model? Not a great look, especially with Apple's reputation for making devices that last a while.

Fingers crossed that iOS 12 fixes it.
