Jedi Outcast texture problems.
 

First thing I noticed is that the metallic frame texture around the hud is moving upwards all the time. Here is screen of it.

Now, I would have no problems with this, but then there are some textures around the map, which don't appear correctly and are moving around in a weird motion. As you can see in this screen, a computer is supposed to be there, but instead I see this mess. And it happens at many places around the first stage. It's really unusual and I can't play like this.

I have the latest patch, and my videocard is ATI mobility Radeon HD 3470 with latest drivers installed. Hope you can help.
