Texture swaps/Spine

Hello,
I want to do some optimisation and decided to define some texture groups. The sprites imported from my animation program (Spine) do show up in this list (Tools -> Texture Groups) but they are not part of the texture page preview (Game options -> Graphics -> Texture page size -> preview). I also noticed that i've got good fps (4000) but a lot of texture swaps (around 40 -50, info from debug overlay). I've got around 100 objects with unique animations but only around 30 are active at the same time. I guess each of this objects with a Spine animation is a spereate texture swap because they all have their own texture page exported from Spine.

I searched the web for answers and it seems as long as I'm not planning to make a port to mobile this shouldn't really matter. FPS good = all good?

Does somebody have some insight or thoughts? Thanks!
