I apologise if this has already been posted, I tried a search but couldn't see anything.

Please see the video for the problem: http://www.youtube.com/watch?v=Hw2d5My_7oc

Basically it's as if a ghost image jumps below the main one.

(I've only just started, so can't tell how far it goes in, but for the intro story it happens, for the first video of Geralt running away, it doesn't. Game play seems normal as far as I can tell, except for his ponytail going odd during the first chat with the King). It makes my eyes hurt, though, so don't want to play if it's going to keep happening throughout! If there isn't much of that kind of text,t hen I can ignore it...)

In the Catalyst Control centre I've tried switching it to use application settings for everything, no joy.
I've tried it in all the graphics modes - high, medium and low, same problem.

Update your graphics driver from AMD.

If that fails, try disabling Catalyst AI or killing any background programs.

Make sure it is the latest driver, AMD do monthly driver updates and the latest I think is 11.7.

Catalyst AI is under Gaming>3D Application Settings and 3rd one down (your version may differ, I don't know).
