I didn't notice any change in stuttering or crashing since the patch, what is it they think they did.

Many people say that they have less crashes and instability, the patch helped with engine problems.

For me they made the game stop freezing, and getting all choppy, and slow. I played for 3 hrs last night on a 11mb 260hr save and it frooze 0 times. On a ps3 before the patch I would have thrown the game out the window if I tried to play 3 hrs no fast travel, and running.

Same here, I had to turn of my Music & Radio off in the setting because it would freeze so much (Freeside was awful). Today I strolled through Camp Forlorn Hope while listing to the Radio when It hit me: I would have freezed by now.
