Game crashes about 1 minute into fighting Aurelia. And of course there's always menu and co-op lag

The game freezes and makes a buzzing sound about 1 minute into the Aurelia fight.

Also lots of people still having lag around opening menu and co-op play. Fast Travel is really not so fast with upwards of several minutes to get to another map and another 15 seconds waiting to be able to open and see your inventory.
