In this Order-
Textures
Ewi's Big Texture pack- Comprehensive and very high quality
Poco Bueno
NMC's (washed out wasteland is good)
Vurt's Flora overhaul
Improved LOD noise texture
MG Neat Clutter
AmidianBorn stuff
Weapon Retexture Project
High Res Chems
Characters-
Fallout Character Overahul- Top quality NPC appearance improvement as well as loads of extra options for character creation. Can't emphasis how good this is!
There are also male and female body replacers if you like.
If you are seeing neckseams, try this-

Lighting-
If you want improved weather as well as improved lighting, go for either
Nevada Skies or
Project Reality. NS is more stable imo, but still had it's problems for me. Project Reality is higher quality, but has some bugs and poor performance.
I simply use
FNV Realistic Wasteland Lighting, which does not add weather, but changes the entire look of the game and is very good imo.
Then install:
Interior Lighting Overhaul - Really makes a difference.
Electro City- Adds lights around the Wasteland
Mojave Nights- High-res night sky
Imaginator- lets you control many aspects of the graphics
Then either add an ENB(which I haven't found a decent on tbh) or Sweetfx which I do use, and recommend...I find you can get the same results as an ENB by using Imaginator + Sweetfx.
You can also use the
NV configurator, which lets you edit the INI easily and is a very handy tool.
All very easy to install through Nexus Mod Manager. The game looks really good with all these...not surprisingly, I am playing it atm
