Mecanim Animation Stutter on low frame rates

Hi! I have problem with character animations with lower frame rates (slightly below 30 fps), i feel it shoudn’t stutter that much!

The setup is like this:
Player (PlayerController) → main controller for the player
PlayerAnimationController → mecanim animation controller (CharacterController,Animator,NavAgent)
(I have animation states that are updated in Update, I tried LateUpdate but still there is stutter)

Maybe i am missing something obvious but I don’t think it should stutter that much, what is the proper way of setting up the character?

Thanks!

any ideas?
