Bless you my good sir!! I've been searching for an answer for almost a month now... lol... You are a lifesaver :D

Please if someone knows how to fix this... HELP!!! :( I hate when this happens.. I don't even want to play skyrim because of this bug

good to hear that you fixed your problem. :D Cheers!

Maybe increase the audio cache size? Also try what this person said

Definitely Project Beauty.. I've played the whole game with it.. and I got scared when I removed it for a little bit... it makes a lot of difference, trust me! :D

Give more info... What mods are you using.. Does it do this to all your weapons? Or is it a custom weapon?

Hmm.. you have windows 8.. that might have something to do with it.. maybe the codecs are not compatible.. or something. I know nothing of windows 8. I don't know if drivers have anything to do with this.. because you get this bug when fallout is trying to play a sound file and it can't, due to decoding. You could update your audio driver.. don't know if it will do something but it can't hurt. :D

Did you install it using all LAV? Because I can guarantee you that this is a sound issue.. that can be solved with the right codecs

Yeah you can re-texture almost anything in Fallout 3.. I haven't tried it myself, but there are a couple of videos on youtube that show you how. You should search for Fallout 3 how to re-texture or something. I don't have the links. And you can't take content from New Vegas and put it into Fallout 3 because it's illegal. And if you have the German version you might run into some problems with modding.. because I heard that some programs like FOSE don't work on the German version EDIT: O yeah.. and you can delete weapons from a mod using FO3Edit.. just go to the weapons section in the mod.. and press delete on it :D then save the ESP

Is it a custom assault rifle?

Download and install K-Lite Codec Pack it will fix your problem ;)

Glad you got your fix! :D As for the edit esp's part.. I see that you already got your answer.. so.. yeah guess you know now. Anyway a bonus to that would be to just make 2 more copies of FO3Edit.exe.. and rename them to FO3MasterUpdate and FO3MasterRestore. You you will have an EXE for each operation. It will get rid of the pain of renaming them each time. Also if you have other crash issues.. here are a couple of links that may help. read the comments from this post http://forums.nexusmods.com/index.php?/topic/201495-fallout-3-crash-fix-guide/ and this: http://pcgamingwiki.com/wiki/Fallout_3#Game_Crashes_Randomly

Well I know how to make a stealth field active while standing and by pressing a separate key.. that's why I wanted to improve it. But It doesn't matter now.. because I just finished playing the game and i'm not interested in it anymore.. for now :D Anyway.. thanks for the help, though!

did you install the latest patch? did you install it outside of Program Files? and what are your computer specs?
