3D glitching in demo of Penumbra: Overture

[jens]

Make sure that you graphics drivers are up-to-date and properly installed. That you are running the 1.0.3 version of the demo, http://support.frictionalgames.com/entry/52/

Finally if that does not work I think that you can use the full game version's hotfix on the demo, http://support.frictionalgames.com/entry/87/ that should fix any remaining graphical bugs.
