Summary: UPDATE2 - More patches (Why doesn't Treyarch / Steam even ask to install updates?) and this game is finally starting living up to it's potential. Still has major bugs in the server browser and frequent server-side crashes don't help. UPDATE - I have added a star after a patch and some tweaking. The game is still buggy, but playable. I really hate spending $60. to be a beta tester. This game has tremendous potential that is being crushed by technical fumbles.
Summary: Want to know the word that sums this game up in a nutshell? I'll give it to you: Stutter. I have a fairly midrange system consisting of an AMD X2 7750BE, Radeon 4850, and 4 gigs of RAM. Since my PC exceeds the recommended system requirements, one would assume that I would be able to run the game. Not a chance.
