Since getting my new computer, about two years ago, I have not been able to go to war with my favorite game platform. The tips given in this thread have made it possible to play the game (bought retail, the first year it came out). Since early this evening, I've added the Grey Wolves, and my wife hasn't been able to get me away from the computer!
Thanks to everyone for their input. I had to use a no cd file, and I'm getting about 30 fps. I'm having a little fun with the Naval Academy, before setting out on my first patrol. It's going to be a long night ...
