Black Screen but game still plays

I think your gpu is intel, not amd after seeing the specs of your laptop

I'm sure it's AMD, because my Inspiron 15R has two graphics cards for use, integrated and dedicated, and the dedicated is the AMD Radeon HD 6470M card...and it's not the driver that's the problem, its the fact that its reading the integrated graphics, the Mobility Intel ® HD Graphics card. And I'm not sure how to make it choose the AMD card. Btw, I'm sorry, but I'm not sure also what is a GPU...

GPU = Graphics Processing Unit = Graphics Card

OK, since your problem is making the game detect the dedicated one do this:

Integrated card interferes:

Check the hpl.log found in the the game's save directory:

Windows: "My Documents/Amnesia/"
Linux: ".frictionalgames/Amnesia/"
Mac: "Library/Application Support/Frictional Games/Amnesia/"

and see if you see something like:

"Renderer: GDI Generic
Version: 1.1.0"

If so, this means that OpenGL uses an integrated card instead of your proper graphics card. There are known ways to fix this in Windows:

1) Go into the "device manager" which is found by entering System in Control Panel and then clicking on the "Hardware". Find the display drivers and the right click on the card that is NOT your main graphics card, and choose disable. Reboot and try again.

2) Update the drivers for the integrated card. For example updating drivers for "Enhanced Display Driver Helper (ASUS Other Device)" has been reported to fix this issue.

3) Enter the control panel for the graphics card and set the proper (non-integrated) card as the preffered device to use. Here is how it looks for a user: http://frictionalgames.com/forum/thread-...l#pid34691

4) Enter Display Properties and make sure that the desktop color depth is 32.
