Having some problems while running in Ubuntu 0810

[jondecker76]

Ok, here is something consistently reproducable for me..


I am in the back part of the chemical research lab - where the cameras are scanning with green lights... The framerate here for me is unplayable (less than 5 FPS) - I dont even know how I'm going to get past this part because I can't even play it.
I have tried turning ALL advanced graphic settings off, and even went to very low shader quality and the lowest resolution. But even then, the framerate does not go up.

I meet the minim specs listed by a mile - i have a 2.8 ghz processor, 2GB RAM, geforce 6600 256 MB, and over 500 GB freespace on my drive.

Is there any way to see what is causing this terrible framerate???
