If you are having frequent freezes and CTDs and nothing seems to help, try rolling back your nvidia drivers to 71.89.
I started playing the game with 71.89 and had no problems. A couple of days ago, I updated my long neglected drivers to 81.85 and suddenly I had all the issues that people on this forum have been reporting. After rolling them back, the game ran smoothly again.
Now, this doesn't work for everyone, but I've gotten enough feedback on these forums and others to lead me to believe that rolling drivers back can help a good portion of those having problems.
ATI users.... sorry, I got nothing for you...

My original thread, with more technical specifics about what I did, plus WarX's thread in which he figured this all out before me.

Hopefully the comming patch will make all this moot anyway.
