In an effort to rule out possible configs that do NOT have a problem, please shout out if you can play the game without any crashes or freezes for at least a decent amount of time (say, one hour or more)
If so, please post a dxdiag pastebin or describe your setup. This will help us know what works to rule out what's wrong with the rest of us.
