Ok so I am using a computer with the top i5, 8gig of ram and a 1gb graphics card so I shouldn't be having problems with speed but I am having issues regarding unplayable amounts of freezing after I reach the end of the vault in FO3.
I have tried a lot of suggestions including setting my quad core to use only 2 cores but that has made no difference and seemed to make it worse.
Any help is appreciated because I love FO3 and now my Xbox is not working properly I can only play it on PC so would love to be able to play it.
