Graphic problems with ATI Radeon HD 4870 X2

[Yuhaney]

For the first time ever, I had graphic problems on Penumbra: Overture!
Though, I have had no graphic problems before on any of the games...

But enough of that! If you're using the same graphics card driver, keep on reading, hopefully this thread will help you out!

So, I had:

1. Some polygons/pixels were missing, like ground in the blizzard (at the beginning of Overture) and rocks were missing bottoms. Just like barrels did. They're bottoms were black.

2. Sometimes, when I was using glowstick, it didn't have glow around it. The stick was green but no glow. And second thing were that the screen had some green dots around the glowstick. As well some glitching with the glowstick...

But you may ask:
What can I do with this?!

Well, many of you might read the following sentence from here on the Forums:
Update you're graphic card drivers.

If you haven't done that, do it right away. That MIGHT cause you're problems.
However, on my situation, it wasn't that...
I did have all the latest drivers for my graphics card.

Problem with the game I faced was this:

I installed fresh installation of Penumbra: Overture from my CD and it didn't have the latest patch.

Install 1.0.3 version of patch and you're game works all fine.
