I'm pretty sure I'm not the first person to notice this, but sometimes when I use VATS, the first shot or two works normally, but then the camera suddenly stops moving and time seems to return to normal. Most of the time when this happens, whatever the camera was tracking would've moved out of shot, but I can still hear my character shooting etc and a quick look at the enemy's health after that suggests that all of those shots missed, even though it said I have 95% chance of hitting.

This bug does not happen consistently, most of the time I can get through a couple of hours of game play (sometimes at once, sometimes not) and it won't happen at all. But other times it can happen several times in a row.

I haven't played Fallout 3 in a while but I don't THINK it happened there. Any ideas what this is?
