Penumbra Crazy Mouse?

[beardedchazen]

Hey all,

I have not seen anything on the forums and i was not hoping that someone might be able to help, i just purchased the games for steam and once i launch them i am able to change everything to my liking but after about 30 seconds to 1 minute of gameplay the mouse's sensitivity shoot through the roof and i can not control it but barley move my mouse and hope that i can quit the game or i end up just stopping the process. I have adjusted it via my mouse down to the lowest setting possible and i have also moved it down in the game but it still is happening.

Any and all help would be greatly appreciated.

the spec of my system are:

Win 10
16gb of memory
Nvidia 970 graphics card
I-5 4560K
