Feedback Performance drop: Obi cloth 6.2 to 6.4

[litefeel]

Hi.


I am using ObiCloth6.2 now.
Seeing that 6.4 has memory-related optimizations, so I want to upgrade to 6.2
But I directly update the plugin to 6.4 and do nothing else.
Found extremely slow performance in the Unity editor:
ObiLaterUpdater.LateUpdate() 3ms -> 8ms
