iOS 10 touch input lag on 64 bit devices

Hello,

For some reason, on iOS 10 the touch input update loop seems to be alternating between 30 and 60 Hz (although the FPS is solid 60), this causes annoying "lag" when using touch input to move objects on the screen; i.e UI scrollviews.

The bug doesn't appear on devices running 32 bit CPUs (iPad 4 etc), but exists on all devices with 64 bit capability (with A7 chip and higher).

Using Unity 5.4.3f1

Any input on that matter?

Thanks

 

FYI, That seems to be fixed in latest patch 5.4.3p1
