I played the original version of The Witcher 2 about a year ago shortly after it was first released and I recall that the game ran smoothly and nicely for me. Now I have downloaded and installed the Enhanced Edition, and whenever Geralt runs, the camera seems to jerk with each of his steps. Does anyone know of a way to fix this problem? Its literally giving me a throbbing headache. The problem is even worse on the lowest settings. Thanks in advance.

YOU are a LIFE saver. Thanks! It did work. :-D

Glad my ibuprofen kicked in! Off to play the game headache free now. ;)
