Animation Worker Thread don't work

It seems that I’m unable to check the “Run Updates in Worker Thread”
which is the 4.11 worker thread update for animation optimizing.

To Isolate the issue i’ve started deleting everything. I’ve deleted everything until the one direct animation node is left. Still when compiling this boolean will reset itself. Is there anyone who knows how do I use this new feature?

How can you find out whether Run Updates in Worker Thread is working or not?

I eventually found out the answer to my question.

A silly mistake. I checked the boolean in Preview instead of Defaults.

Not sure if there’s a way. but maybe you can try turning them on and off and then monitoring the stats in animation.
