disable wavy video effects?

[TFEF]

Hmm... Have you tried going into the game.cfg file (located in redist/config in Amnesia's files) and scrolling down to <Player_Sanity? Changing a certain few of those values to zero, mainly the first four, might help you.

I haven't really messed around with those values before, so I can't really tell you what each one of those does.

I assume that the sanity effects are what is bothering you, seeing as those are what cause the 'wobblevision', as I like to call it.
