hi , I have Fallout new Vegas ultimate edition on ps3, i'm on level 38 and i cant complete it because when i load the game it lags continually for about 1 minute and then crashes, so all i can do is turn it of by the console. it started lagging near the beginning of the game, the crashing started later and they just got worse till the stage i'm in now. i quite disappointed about all that, is there any help or info you can give to make the game work please.
