Slow game

Hello, does it take ages to load screens in your game too? I don't have mods nor cc installed, tried to repair the game several times but still it takes so long (never happened before) to go from a screen to another, for example from cas to gameplay or to visit a place, to move or just to load the game... 

I thought it could be the numerous packs I have installed, maybe? I don't know...cause if this is the motive then do I have to remove all of them?😅

Thank you
