So, I am having the exact same problem with road to independance as you are sabot.
For anyone whose played the whole thing, is it worth redoing this campaign to continue on to ep 3? Mainly, will I learn anything important that I wouldn't pick up in my first campaign?
Sabot, WRT your graphics issues, do you have an Nvidia GPU? If so try this maybe:

Also -- you might want to decrease settings, though from what you've described, it sounds like your system is pretty high end.
Finally, I did read that there's an incompatibility with the latest Nvidia drivers, not sure if this is a problem after the latest patch. Google Nvida compatatibilty and ETW to find a link to the most recent working driver (I'm not sure if this has been fixed with the patch.
