Why does Amensia crash the framerate from 60 to 0

If you're running Windows, the save files are under USERNAME/Documents/Amnesia/Main/. I haven't the foggiest where they are located in Mac/Linux.

Ahhh...if it's not occurring at start-up then this is definitely not your issue (the problem I mentioned). I'd suggest posting it on the technical support forums, maybe some tech guru around here has some insight.

I do know that outdoors maps can be taxing on any sort of computer, especially since the game was really intended to support tightly-enclosed indoor levels. Whenever there is a large area, a special static object is used for its layout (cistern entrance, Zimmerman vision). The outdoor level in The Dark Descent was actually pretty sparse in terms of objects. It has a size of <500kb, smaller than some of their indoors levels! So perhaps try cutting down on how many objects you've got in the actual level.
