Amnesia:Lighting Problem

[Jacob55511]

I open the game, everything runs fine, and when I hit continue the torch in the menu interface begins to spaz out, then in game, if theres any light in a room, If I stay still it dosnt move, but as I move the light rapidly moves around as if it was a rotating candle on crack. It been doing this since I downloaded it, ive tried playing it in a window, and tried all the graphic settings and nothing solves it. What can I do?
