If I am to guess, the lag spike happens only for the first Dynamic Variable added?
I’ve submited a new version to the asset store. Apart from the rest, in this version I’ve made an optimization for when creating dynamic variables. Also, the ‘Script Control’ tasks for the iOS is fixed. Thanks for the patience.
Please check the new version when it goes live and let me know if you still encounter any problems with the dynamic variables lag, or anything else.
If the problem still exists, I will make them created in scene loading time like you suggest.
