Ive restarted new vegas like 10 times i have steam ive tried loading it out of steam it just wont save the option

whats the difference between each of them? mine is on large

try going into the console with '~' key and typing 'saveini'? If its crashing on exit it wont save settings, this was a big problem with oblivion... I dont even have FO:NV yet, but its worth a try.
