Framerate issues with Amnesia: The Dark Descent

[plutomaniac]

These errors ERROR: Could not find light are almost always caused by graphics card driver issues. I have the same graphics card and no such errors occur. I have driver 301.24 installed which is one of the latest. What driver do you have? Can you update it from nvidia.com? Otherwise, laptopvideo2go is the only way.

The log shows that the game is being saved etc so I guess every time it becomes even bigger instead of recreating itself. Delete it and let recreate itself after playing again.
