For me the problem is still there, especially when I go to walk around town. Not a minute goes by and it freezes. The spy mission is impossible to accomplish because of it.
Me too, I have hundreds of hours in the game and have had no trouble. Made sure my drivers were up to date and everything.
Even right from launch, when I click to go to another screen it takes longer to load, and I see part of the next screen (IE: in a town then clicking to go to the forge, it sticks for a sec showing me what materials I have at the bottom but I still see the rest of the town's home screen where you choose where to go) And after a few minutes it just stays like that till I tab out and manually close the game.
