How can a game that runs reasonably smoothly at 45-65 fps offline suddenly go to an unplayable mess at about 22 fps online? These are on Australian servers with good pings at around 40. I tried posting in the troubleshooting board but with no help.
I need answers quickly because I have to return the game to EB within a few days if I can't get it working. It's been very disappointing so far unfortunately.
