I have never had a game like this that constantly crashes in MP. You either cannot connect or only last a couple of minutes before you are booted out! I hate to say it but BF3 works absoulutley fine so it cannot be the memory usage - can it!
It is really winding me up as I wish to play a couple of MP games, I loved RDR and had not online issues with that - so whats the story R* ????
