I did some research, and apparently there's some kind of bug with some new hardware and the way faces are rendered. There's actually a simple unofficial fix that makes F:NV think that you're running an older graphics card than you actually are that drastically improves framerate (it apparently doesn't work all the time, but i'll try it anyway). Ironically this is a very similar problem to what FO3 had and it's apparently even the same file that is causing the problem (some direct x dll file). If you ask me, i think it's really unacceptable that bethdesa and obsidian have the same recurring problems with their games. in that same vein it is extremely annoying to rely on 3rd party mods and utilities to fix gameplay and technical issues to make a game playable, if i'm spending as much money as i am on my shit i want it to work the first time around.
