The thing is, there may indeed be some kind of workaround, but in my opinion, especially where people are running a popular rig, nVidia or Ati cards, Vista/XP, blah, blah, blah.... we shouldn't have to try to tweak things to get basic functionality or to simply make it playable.
OK if someone has a really old rig, or something not mainstream I can understand it; but from what I can see everyone who is encountering problems at this stage has set ups with their software and hardware that are "normal" and still it's not working.
I'm playing (or trying to) the Dogs of War mission, sometimes my people won't move, sometimes there is a vehicle available, and then when I do load the mission up and try to get anywhere, it crashes when I try to save it.
It's highly frustrating and I wish someone from BI would say something, like acknowledge there's a problem and tell us there is a fix on the way, even if it's a couple of weeks away, but being left in the dark and not knowing if/when there will be a fix just makes things so much worse.
Rant over.
