Penumbra: Overture mid-game crash - JENS TAKE A LOOK PLEASE

[Bludo]

Are you sure the drivers are up to date and that the game is running on the nvidia card? Because it is a bit strange that it uses fallback shaders for lights and fog on a modern graphics card.

I am 100% certain they are up to date. Further, the Nvidia architecture has not altered their implementation of the shader interface since three revisions ago.
