10 fps in cutscenes, packs, kickoffs

The game runs smoothly and everything is fine until I open the pack, at the beginning of the opening I always have approx. 10 fps and after a while again 200 and more. The same thing happens in the cutscenes, at the beginning of the match, I don't know what to do with it.. I have a new computer, very powerful. I want to the game run smoothly. Please fix it.
