Hi there!
I just bought a retail copy of Penumbra. After i installed the 1.02 patch i faced some very odd and anoying garphics glitch alle over the scenes.
I did some trial'n'error testing and found the file "Diffuse_Color_vp.cg" to causing the problem. I installed an older version of this file and the most anoying one of the graphics glitch disappeared
I'm using two HIS IceQ 3 Radeon HD3870 graphics cards in crossfire mode with the lates CatalystÂâ„¢ driver
(8.4).
I hope this will help others who have graphic glitches on an ATI Radeo HD/X-Series card.

P.S.:
You may also edit your "Diffuse_Color_vp.cg" manually with notepad or any other text editor and copy'n'paste the following text into it.
