I heard it got patched tonight, not only PC but 360 as well.

Yes, I did get an update earlier today, but I'm not really sure what it is intended to fix.

If you guys refering to the first patch, its for scripting and quest bugs.

Pre-patch, the game had frozen on me twice during the loading screen — it froze entirely.
 
Post-patch, the game has locked up 3 or 4 times during the loading screen — the spinnning roulette wheel just spins forever, and the background/game tips keep changing.
 
Literally the only real difference I've noticed so far :/

the only thing i noticed was that pre-patch, you could save before playing a round of any game in the casino, go all in and if you lose just load the save. post patch they have it so you must wait a minute before playing any casino game after you load a save.  
other than that im on the mission Eureka! (last mission for NCR) and it crashes everytime i go through the same door.  i really wish they had actually fixed glitches and crashing in the game instead of making it harder to get easy bottlecaps

Loading times haven't improved, that's for damn sure.

I cant definitively state that the update was the cause, but now my character's arms and weapon flash in and out when in 1st person.  It is really annoying, primarily because you don't know if you have a weapon armed.  It happened occasionally before the patch, but not to the extent that it does now.  Of course it could just be getting worse as I spend more time with the game.  Anyone else have this problem?
