The Lagsome Road

So far, I cannot play Lonesome Road for 5 minutes without having to reload an old file or turn my PS3 off altogether. Does anyone else have this problem? This is making my game (The one I paid 10 fucking dollars for) utterly unplayable and more frustrating than enjoyable. It literally takes me about a minute to open a container and 5 minutes to navigate my pip-boy. What the hell did they do for all those extra months the game was delayed anyway?
