Can you please download and run Amnesia The Dark Descent Demo from here: http://amnesiagame.com/#demo and tell me if this works?

1. What operating system do you have? Also 32-bit or 64-bit? (Probably Windows 7 x64, right?)
2. Is it a laptop or a desktop? If a laptop, what model? (Most probably Desktop, right?)
3. Attach me here the file HPL.log found under Documents\Amnesia\Demo folder.

PUT THE SHADER ON MEDIUM the shader option should be under graphics
