11.4 is rubbish. My iPad Pro 10.5 has gone back to jitter and lag. Can't believe they could stuff it up this bad with the specs the iPad Pro has.
All versions of iOS 11 suffer from jitter and lag on the iPad Pros. iOS 10.3.3 still had this but it was
way smoother than all versions of 11 by comparison. All I want is iOS 6 levels of smoothess and stability back, only
then will the 120Hz refresh rate be fully taken advantage of. This can only be done in software because as has been evident; throwing powerful hardware at crappy software still results in stutter. I can only hope that iOS 12 mitigates this, key word being "
hope" there. Apple's software as of late has caused me to lack confidence in them, so I'll be tuning into WWDC expecting the worst to avoid disappointment. I will then wait for the beta to drop to see for myself if the smoothness is really back. If it isn't then I'm switching over to Windows and Android because I'm not standing another year of it.
