Graphics errors - first scene

[Blazter]

Im also having this graphics errors. Its not only in the first level. What is strange is that the graphics are absolutely perfect when you are reading about things in the game. Like a paper.
The missing items is fixed by turning off the Noise Filter. Then the Motion Blur will go crazy so if you turn off the Noise Filter, then turn Motion Blur off too. With these two things off and everything else on max the game runs with only some errors like flashing textures sometimes. But sometimes even then the graphics can get a little crazy but it stops again, if you are lucky. If I press Esc the game in the main menu mostly of the times freezes.

A permanent fix seems to turn the Shaders to very low but then the games darkness goes away so that is not a option for me. Im running Windows Vista 64bit with a Radeon x1950 Pro.
