Thx for explanation.
But unfortunately problem persist even when i switch to 20 tps

It only happens when i get in to CC...
Let me explain this moment.
1) When routine healing all the raid on the RBG I'm getting around 100 - 150 fps (in this moment routine working hard, cerebrating logic whom it will heal and how)
2) When I'm getting in to CC, and stay in Control actually doing nothing in this moment fps drops to 20 fps (in this moment routine only must cerebrate how to get out of CC, if i got trinket for example it using it, if not - just waiting for the end of the CC).
So. It's not obvious why fps is drooping so much...
Don't think the problem is in my Tyrael settings, coz i tried it even whiteout any lock and 20 tps.
