Lagging mouse movements

[Ian]

Hello there,

I got Amnesia on my old Desktop, which doesn't work at all, so I got it again on my girlfriends new computer.
When I loaded it up all the menus were going VERY slow, I couldn’t even get past the Profile screen.

I read the guide and played about with the settings, turning SSAO off seemed to work fine, even with everything else set to Low, and also Medium.

So now...
When I try to play the game the mouse movements are very laggy, I have checked the movement speed on the ingame options, and smooth is selected too. How can I make the mouse movements work properly and what is the best settings I can use for clear gameplay?
I play it on 1600x900,

I just really want to get playing this game now

here is the log:


Thank you
