[solved]Screwed graphics

[Urkle]

Currently I do not provide an "uninstaller", simply it's removing the game installation directory and the ".desktop" entries that are created. (which you'll have to search for.. PenumbraOverture.desktop and PenumbraBlackPlauge.desktop and PenumbraRequiem.desktop)

Penumbra uses Nvidia's CG library which compiles the shaders into various targets depending on the card. (several nvidia specific targets, ARB target, and even a GLSL target).. so if the Mesa driver doesn't have descent shader support that could be a slow down cause. You can Force the shader backend by looking in the hpl.log (which lists which shader profiles are supported) and then setting the profile name in the settings.cfg (there are two options, one for Vertex and one for Fragment) Both of these files can be found in your ~/.frictionalgames/Penumbra/Overture folder.

I know someone else who has the same issue you are having, but with Regnum Online. He has the older ATI cards and is fighting with the Mesa installs to get the game running. right now he's at the point of waiting for some $$ and then he's upgrading his system and using an nvidia card.
