The game has serious problems. No one can deny that. google FONV bugs. you will be amazed
Wait your saying NV is buggier than F3?
LOL I enjoyed F3 to bits but that game was buggy as hell! Fallout New Vegas is buggy, yes everyone knows this but Fallout 3 had a huge amount of dev time and STILL has major bugs.
Not to mention Obsidian was forced to use Gamebryo, had a much smaller budget, a smaller team, and a LOT less development time for New Vegas.
Now please go be a blind really devoted fan elsewhere.
To the OP, the patch fixed a lot of problems. I have about 15 hours of playtime since the patch and I have only froze twice (when I very first got it.) Everything else has been smooth sailing.
