Well i find a fix for crash&freeze.Only you need to delete option save(setting save)it is a folder with a boy and with a tool box.I delete it and i have no crash&freeze.Hope it work for you guys

Done that already, it didn't fix a thing.

well work in Fallout New Vegas but my Firmware 3.72 is corrupted by Fallout New Vegas crash:(

It's either patch 1.07 or the firmware 3.72 that killed the game for Ps3 users.

yeah it has to be the Firmware update

WHO GIVES A TOSS WHAT IT CAUSING IT? IT IS NOT ACCEPTABLE!!! I WANT MY MONEY BACK! I CHALLENGE ANY PERSON OR MOD THAT WORKS FOR THIS COMPANY TO TELL ME WHAT IS WRONG! IF NOT WE ALL WANT OUR MONEY BACK!
SIGN UP NOW PS3 OWNERS!
JUST SAY-
WE WANT OUR MONEY BACK !

So, the only way I found a fix was to delete all my DLC's. Unfortunately you loose any of those weapons, money spent on DLC items and the higher level caps but it is the only option I found to work to keep my current save games playable. I'll probably try to reinstall the DLC's at some point to see if it was a corrupt DLC installation but it works for now. Luckily I only spent a few thousands caps on DLC items and didn't start any of their quests yet.

Try to re-install all the DLCs except the items ones and tell us if the lag is gone.
