That will help, but unfortunately it makes some things rather ugly, especially the dock.try reducing transparency.
Settings > general > accessibility > increase contrast > reduce transparency
I've noticed the lag has gone away for my 5s
Doesn't with iOS 9. Control Center is just as laggy. It's something with iOS 9 and Metal on the 5s.That will help, but unfortunately it makes some things rather ugly, especially the dock.
If only that didn't make the dock so ugly/out of place.Yes. If you turn off transparency the stutter dissapears almost everywhere. It feels better than ios8.4 that way. The thing is, you shouldnt have to turn off that to have a great performance on such a powerfull device (6 plus here)
Worst optimixa
Yeah the dock is rather ugly sadly. When I jailbroke on 8.4 I downloaded a iOS 6 theme and the dock on that was 10x better then the dock on iOS 7/8/9 imoIf only that didn't make the dock so ugly/out of place.
