Ok online use has nothing to do with it? Then how about you disconnect your online network and see if you can purchase ANY dlcs and then come talk to me because developers have to sinc add ons with 360 or Ps3 for gamers to be able to purchase them and some systems are easier to do that than others.
That's the actual physical download of the DLC, what does that have to do with it
performing? You're talking about two completely seperate entities of a DLC, the physical download and then in-game performance.
btw, you can update lots of PS3 stuff WITHOUT a connection. All you need is an external HDD and a basic computer with internet connection, which you could go find in a coffee shop.
I'm just trying to make the connection here between making a DLC work on a system and it's ability to download it from the store. Please answer me that. I have just never seen anything in relation to the DLC to download properly off of the network that is causing problems. If you got a link that this is the case, please share.
