Here's an example:
First it looks like this: http://i.imgur.com/r2Rhh.jpg
When i take a few steps forward it fades quickly to this: http://i.imgur.com/Z30IF.jpg
When i take a few steps back again, it returns to like in first screenschot. Fade level shifts in certain places even when standing still and looking around with mouse.
Dynamic contrast is disabled on my lcd. I use nvidia forceware 295.73 on 460GtX. OS is Windows 7 64-bit. Is this a normal behavior of the game or some driver issue?
