The character and enemies move very slowly (Nioh)

Hello, fellow gamers! This problem. Downloaded Nioh: Complete Edition (just saying - the pirates). Launched and there was a problem: the game runs extremely slow. That is, the character and all enemies are moving, barely, as if in honey. After a restart at first all goes normally, and then again slows down to an impossible condition. Climbs enough sites, but have not found the answer.
The caveat is that some time ago, I was playing this game and had the same problem, but I was able to find a solution and after that time, the game flowed as it should (i.e. not in a computer case). What I did remember well, can not.
Someone had this problem, perhaps know the solution? Thanks in advance.
