Question Digital human and snapper system performance question

Hello!

I am working on a project that requires facial rig and animation. I started testing digital human demo and I can say that the quality is really good but performance as I see it is unacceptable for game.
After a while I found out that Unity disabled Burst and incremental GC for some reason. Enabling it increased my fps from 20 to 50 but still too low. I checked the profiler and I see that most of the time Snapper system spends in the skinned mesh baking step. If I disable it the attachment script starts to work incorrectly but fps goes up to 120.

Can anyone recommend what approach to use for the facial rig?
Is it possible to somehow tune the snapper system to increase fps?
What you think about using tech like Digital Human for game? Especially, Facial Rig.

 

That is very good question.

 

And I still do not have good answer for that
