This is meant to help anyone with issue in fallout new vegas, as I had issue also at first. This is supposed to be a friendly discussion to help all of you newcomers to the Fallout World enjoy it even more. So Ill start with my first fix:
My Amd FX-series processors CPU lag fix-
Step 1: Go to Documents>My Games>falloutNV> and open fallout.ini
Step 2: Find the line:
change it to:
Add another line after it and insert:
iNumHWThreads=8 (This is dependent on the processor, Set it usually to your max cores, so with me that is eight being I have a Fx 8350 8-core)
I always pay for my games, just to put that out there. But as to buggy I mean as Choppy and unstable just playing, unless you play vanilla, you will most likely want to mod and add texture packs like Nmc's and so on. This reduces performance like usual.
