I thank you in advance for reading my post, as many forums don't even bother to look at technical support threads 
As titled, I get a perfectly smooth frame-rate indoors, but when I go outside, it gets hit HARD. I've reinstalled several times, no dice, .ini file tweak (iNumHWThreads and bUseThreadedAI), no dice. The only mod/plugin I have installed is fallout stutter remover (I also have FOSE and the 1.7 update set up). Additionally, I've made sure to install the game NOT in my program files x86 folder, but right in the C: drive. Any solutions?
P.S., I also get some nasty input lag when the fps drops. I can look at the sky and my fps will go back to normal, but once I look down at the terrain or whatever, that's when it goes down. I've fiddled around with the nVidia control panel, doing things like setting pre-rendered ahead frames to 1 and 2, forcing v-sync off etc. Apparently, I should be able to max this game out and run it smoothly. It's just not happening.
Specs:
Intel i7 3770 at 3.4GHz (not overclocked)
nVidia GT 640 2GB (brand: Asus)
8GB RAM
2TB Seagate Barracuda hard drive at 7200RPM
running Windows 7 Home Premium at 64-bit
