The mysterious stranger comes and goes. Some of the time he's fine. He kills the target and game runs smooth. Most of the time there is a massive lag during the cinematic and my character is frozen while taken punishment from nearby enemies. To top it off, on occasion the game freezes completely during the cinematic and I'm stuck restarting the PS3. He also killed the legion soldier I was questioning in McCarran (which I read another post saying that this will happen, too bad I didn't read it first). These things happen alot. I wish I could deactivate it as it is infuriating. This game sure is glitchy.

At the moment I'm frozen while collecting the cazador eggs for the Thorn if that helps (new vegas).

Yeah, mysterious stranger is very glitchy, simply because VATS camera is buggy. Sadly, there's nothing you can do. And by the way this is FO3 PS3 issues, not FONV
