How to control the FPS for a single type of monos?

Hi,
In my current game, I use lots of Spines, Update() and LateUpdate() of SkeletonAnimation consumes a lot of CPU time. I need to optimize this. Set UnityEngine.Application.targetFrameRate works, but it reduced the quality of the entire game. I need a way to only reduce the call of SkeletonAnimation Update() and LateUpdate(), for 30FPS, and the whole game for 60FPS. How to do this? Maybe FixedUpdate() can replace Update(), but how to deal with LateUpdate()?

 

You could include a counter in the scripts you only want to run on some of the calls. In every Update() you increase the counter. When it's still below the needed threshhold, you return; if the counter is high enough, you run your code and reset the counter.

Produces some extra overhead obviously, but maybe it's sufficient.
