Are there any HD Texture packs for this game?

If you're playing games for textures and HD environments, I suggest you'd go playing Far Cry 3, or wait for GTA V or something.
TDD is about atmosphere and horror, not for fancy textures... Although, there are some high quality entities that were released on the forums, but not many.

Amnesia isn't some sacred work of pure perfection handed down from the heavens, relax yo'self son! It's OK to enjoy other games and it's OK to enjoy visual fidelity; it doesn't mean you're intellectually deficient or shallow.
