Okay so my problem was the game crashing whenever I approached the cemetery in Goodsprings. I'm running this game, store bought copy, on a Windows 7 PC with 8GB ram, an Nvidia GTX280, close to 4TB of free HDD space and an Intel core 2 Quad 2.66ghz cpu. Fallout New Vegas is the only thing aside from Firefox installed on this PC and all software, including drivers, is freshly installed and updated. I didn't see the stuttering issue that many other Nvidia users have reported on this forum, the game would just crash and would not wipe out my saved game as reported both some other people on this forum.
I wound up disabling auto-save and following the advice on this forum involving changing water rendering to the low. I also set the game to run in windowed mode. Also, I disabled the kill cinematic.
The result was that the game stopped crashing. I had it running for 7 hours without an issue yesterday. However, despite my best efforts, the game refused to run in windowed mode and each time I try to launch the game through the Steam thing it installed on my PC, I have to set the water rendering settings each time I launch the game. I still tick off the windowed mode checkbox in this tool but, that setting is always ignored.
While the game didnt crash, I started seeing the stuttering that others have reported. Additionally, the game would get laggy if I went too long without saving. I didn't try to push it to see what would happen if I didn't save the game and, instead, tried playing through the lag. Finally, with this setting, I would notice rendering issues - almost as if the draw distance wasnt quite high enough. When approaching the wall surrounding new vegas, I was a little surprised to see buildings pop up between me and the wall after the wall had already appeared. I've noticed the same thing with random things around the wasteland - tree's, etc. This was *not* happening prior to changing these settings.
Anywho, I don't know if any of this will prove to be helpful to any of you but, I hope it's helpful to someone.
