I can't tell if this is just FONV just being crappy, which it is well known for, or if this is a TTW problem, both, or something I'm doing.
Before you ask, here's a rundown of what I'm using, besides TTW's files.
FalloutNVCheatTerminal. (I use it to teleport Boone to me when he gets lost.)
pipboy nightvision (It makes it so the Pipboy's light doesn't suck ass.)
Centered 3rd person Camera.
Casino Exchange All (I can't stand sitting there and clicking 1000 chips every time, so annoying)
Casino Bypass (This makes it so I can take my guns in to casinos. Never know who's gonna step to you, so I always like to have my guns on me at all times.)
Casino Bets (Just increases the max bets for casinos)
Purge Cell Buffers (Someone said to try this to help with crashing, but it doesn't seem to help.)
Basically, let give you a run down of what happens. When I first load my save, everything's fine and dandy.
After about 2 or 3 load areas, looting bodies start to take a tad bit longer to load, but it's nothing serious. (This seems to be reletiive to where I am. When I'm in Tenpenny's loby, it's super long, but when I'm outside, it's super quick)
After about 5 or 6, it will start to get sluggish. Frame rate drops from 74 (which I cap it at) to about 60. (Not a severe difference, but it's telling me something's wrong.)
Then after that, one of the loads will crash right before it finishes loading.
It's kind've annoying, because if it's something like where I just walked 5 miles accross the wasteland to something and then it crashes, it can be very fustrating to have to reload FONV just to walk that 5 miles again.
