Whoops, forgot specs.
Windows XP SP3
Creative X-Fi
4GB DDR2 800 RAM
GeForce 260 GTX
Running Steam version of Fallout 3 with the latest patch (plus unofficial patch and stutter remover fix, though this specific issue was happening back when I played it at release).
Sometimes when a Brotherhood/Outcast member starts talking, usually in conversation with another, they'll say one or two words, and then suddenly stop. After a short pause, the person they're talking to will continue on.
Any ideas?
