I am having issues with the DLC of fallout 3. I bought the disk for downloading them. They all lag and freeze, but most of the time it is not much, but the quest "Into the Pitt" messes up the most out of all of them. It doesn't load many of the things in the mission, such as trains, half or all of the Pitt Bridge, and it lags a lot if i am able to get across the bridge and then freezes while it loads when i enter the next area. i have tried deleteing and realoading the DLC, but it has not worked. is there anything else you suggest i do?
