Crashing every 30 minutes or so, among other issues : Fallout: New Vegas

» Wed Mar 27, 2013 8:00 am

New Vegas has been crashing a lot recently for me, and to be honest i have no idea whether this is a load order issue or not. The most common crashes are freezing when loading, or crashing upon pressing quickload. I am also sometimes forced to start a new game and load my save from doc mitchells, as when i press continue, the game stays at the loading screen forever. I am also experiencing lots of texture glitches, as well as the entire world disappearing/turning into the sky for a few seconds. Any help you can give is greatly appreciated. On a slightly unrelated note, my fps is usually in the 30-45 range, which is less than i would expect out of my machine. Using a GTX 670 and 8 gigs ram, i5 3570k @ 3.4. ghz. Furthermore, i am now experiencing two other problems, being that i cannot find rex, who was previously with me (and people still say things like hes there), and water glitches out every time i get near it. (attached picture). Sorry this is a lot of info, and not that well organized.

My load order is:
FalloutNV.esm
DeadMoney.esm
HonestHearts.esm
OldWorldBlues.esm
Project Nevada - Core.esm
Project Nevada - Cyberware.esp
Project Nevada - Equipment.esm
Project Nevada - Rebalance.esp

I also have NMC's Texture Pack Large installed, as well as an ENB thing.
Oh, and am using archiveinvalidation invalidated, and launching from a 4gb version.
Attached are some screenshots of the textures glitching.
