I have now spent around 30 hours playing this fantastic game without glitches or freezing and i am well chuffed to say the least.
I have noticed that a number of members on this site are still having issues even after the patch has been released.
May i suggest to all new vegas players that they turn off all automatic gamesave options from the menu and only create them manually via the start button,i have done this myself and can honestly say i think this is the only reason i've been able to play through 30 hours without freezing issues.
