Hi, I installed the patch a few days ago but haven't found any time to play until last night
I have the Debian package of fglrx 9.8.2 installed on my Lenovo T400.
OpenGL vendor string: ATI Technologies Inc.
OpenGL renderer string: ATI Mobility Radeon HD 3400 Series
OpenGL version string: 2.1.8870
OpenGL shading language version string: 1.40
Not a blazing game machine, but should be able to play Penumbra I think.
* Medium and lower shader quality settings result in psychedelic dancing textures
* High shader quality seems to work well, with no disappearing objects and no dancing textures.
* Performance on this machine is on the lower edge of acceptable with High shader quality and all advanced graphics options Off (Static shadows tho).
* I don't use Pulse but the default sound works fine.
