It should be noted I can play Penumbra perfectly with moderate settings. But if that uses something different than this one. So be it I suppose. If anyone else has any ideas, feel free to share them.

I will most likely purchase Penumbra; however, a customer is lost with this new game until there is better support for a wider range of people.

Well, for one, Penumbra uses an older version of HPL. Amnesia has updated features, so that may very well be the cause.
