sigh... I am alone.
Forgive me for bumping my own topic, it's just that I'm desperate for help.
I've continued tinkering with the graphics and I've discovered that the lighting works perfectly when I don't have full screen enabled. Does anyone know why this might be, is something in the coding changed when switching between the two screen options?
Devs, anyone? Not being able to play Amnesia properly is draining my sanity, I fear soon I will be crawling on the ground with blurry vision while screaming incessantly.
EDIT: Had a look in my hlp log and found this right after experiencing my lighting problems.

I've uploaded the full log as well, hope somebody can help me.
EDIT 2: Just added another log from a different savegame. To be clear, I'm not getting the errors ("Could not find light"/"does not exist anymore") in the log or the lighting problems when I don't run the game in full screen.
