so ocasionaly in certai nareas when im facing a certain way liek twoards my objective my screeen gets taken over by a bunch of flashing lines and triangles that kind fo spout from teh middle of my screen and i basically have to walk backwards just so ican see clear but at the same time this prevents me from being able to see or atatck my enemy

but this only happens when i have a bunch of fallowers like at the end quest before broken steel starts (i hope i didint say too much) any way is this glitch common for anyone else or is there soemthign wrong with my disc (i hope not this game is awesome and i had to wait 4 weks to get MW2 resurfaced i doubt id be able to survive with out fallout for that long! i almost didnt survive not being able to play modern warfare 2 (luckily i got fallout before i went insane)

Yeah I've heard complaints about this before, I think it's pretty rare and it won't hurt your game. If all else fails, reload.

This used to happen to me when I uh... would play for extended periods of time, like over four hours. Save your game. Turn off console. Let it cool for about 5 minutes, reload that save.

ok thats good to know ^.^

Sounds like you're artifacting, maybe invest in better cooling or get a better GPU.
