Black screen issue, game loads fine but no graphics

[jovianeye]

Hello, I have been having a similar black screen issue with my Amnesia game as well. I start the game, use the launcher, see the main game menu, hit Continue, and the game loads. However, when I would expect to see some graphics for the environment, there is only a black screen. The hints and chapter titles appear, and when I hit F I hear the lantern sound, but the screen remains black. I have looked at several of the troubleshooting threads to no avail.

I am running a Lenovo W520 laptop with the i7-2720QM, 4GB of RAM, 64-bit Windows 7 Pro.
I also have the NVIDIA Optimus setup (dual graphics cards) with Intel HD 3000 graphics and the NVIDIA Quadro 1000m.

Within the past week I updated the driver for the NVIDIA card, but I had not tried playing Amnesia for a while before doing so. I have run the game a few months ago with plenty of success.

Thanks for your help!
