I had similar issues with my rig, and it turned out to be a video issue when I had updated to newer drivers, apparently the older software didn't uninstall. Over at 3Dguru, I found a little utility that removes all ATI software, and after using it and reinstalling the latest drivers, I've not had any problems, and more stable fps too, no longer any problems with jumpimg from 30 to 90 fps with an annoying stutter too. Also no longer have distorted sound either. The game runs at 20 to 30 fps solid depending on what's going on. Lower fps for lots of things, and higher fps while cruising the shipping lanes.

If you've recently updated any drivers, try uninstalling them and searching for any left overs, then clearing the registry of anything related to the component that's being updated, then reinstall the drivers. You may want to turn off all the options in your vid setup too, and then add them back one by one, to see where it starts to wig out on you.

I've not had an Nvidia card for a year now, the 256 GTS was the last one.
