I was having issues as well that went from the occasional "transitioning" errors to full crashes. Could it be a GPU driver issue? I had to update my Nvidia Driver to a Beta driver on Saturday and it seemed to fix the issue, for now.
Hopefully Dice works out all of the kinks before the next Battlefield game.
Second assault was released today and I started playing, got through 2 games with no problems then on game 3 I would spawn, then soundloop. Anyone else have this going on?
