Mouse is turning always. I can't stop it

[Kental]

Hey everybody

i'm not good at English, so i will tell you simply.

I bought this game on Steam. Then, downloaded it.

When i started game first, mouse was turning crazy after first scene.
I created new user and i had that problem again.

So i went out from game. i entered game and created new user.

after scene, mouse was turning again, but it was slowly.
It still turning.
İ hope i could tell you.

What can i do for this problem ? Do i give you Steam ID or take a video for this ?
