*shrug* As I said though, it was weird, inside Wellspring no fps change, soon as I loaded into the wasteland, it was at 4-6fps. I even sat there a good minute or two, to see if it was just trying to load everything at once.
Update: After you mentioned your fps. I decided to try it again. This time after turning the option on, restarted the game. Loading into Wellspring no issues 60fps, loading into the Wasteland 4-6fps. Waited roughly 3-4mins, and finally everything was back to 50-60fps, though I was noticing some stuttering while walking/driving even after that. I then loaded back into Wellspring, everything was normal, then back to Wasteland, and back to 4-6fps.
So I guess every new non town area will run like shit every time I load into it while it's doing whatever it's doing. I'm just gonna keep the setting off, I didn't see a massive difference anyhoo.
