I have a pretty old rig that just barely came in under minimum specs, but when I first got the game, it ran really well. The initial loading screen took a little while, but the game moved along just fine. But now, the loading screen takes like 4 rotations of that whole song to get through. And it's not even because the save is more complex, it's taking a lot longer even for new starts. Restarting didn't seem to fix it. I guess I'll just have to hold on until they crank out a few patches that run it more efficiently.
