Black Plague Black Screen.

[Tombstone]

Ok, so i discovered Amnesia: The Dark Decent didn't work for my computer cause of the processor. But i heard Penumbra doesn't need a good processor to play so i got it. It works fine in the tutorial and starts up perfectly. But when i try to start a new campaign game it says loading. Then 5 seconds later it just goes black, i am not able to play the game. I will post my hpl under here as along with my comp specs.

There are a lot of errors in the log, check your drivers and make sure they are up-to-date (by downloading the latest available from the manufacturer) and in a working state.

The tutorial works because it is a very simple map and when loading the first actual map things get a lot more complicated.

[Bek]

What video card do you hve? Running through steam? If not have you patched the game? If so, have you tried verifying the game files through steam?

[plutomaniac]

Do what Jens and Bek say and the problem should be fixed. It could be the installation or driver issue. What graphics card do you have and what operating system? (x64 is not enough of course)
