Hello. Im new to this game and I installed it like week ago. Generally everything was ok, game was smooth and i had ~100 stable fps on maximum settings (pc)

Today i created new character, andd... its kinda crap because i have like 20 fps with drops to 10? whats going on? I didnt change anything with my pc

my pc specs:
nvidia geforce 1060 6gb
intel core i5 6500 3.2ghz
8gb ram

On minimum options i have 90 fps with drops to 50 and if it drops to 50 my character is like moving slower then faster when it backs to 90fps..
