How? I'm guessing it's ENB series? Any texture mods?
Main graphical mods i'm using are:
ENB series for New Vegas version 0.121, with
this Trillville preset applied and SSAO disabled (too buggy)
NMC texture pack
Western Sky
More Grass
EVE
Wasteland Flora Overhaul
Those are the main ones I think. Also it's downsampled from 2560x1440, no AA (I couldn't get SMAA to work without crashing because I use the 4gb launcher, NVSE and the stutter remover script. Real AA is unsupported by ENB). I locked the framerate at 30 using the 1/2 vsync setting in Nvidia Inspector and it is perfect.
As for gameplay i'm running Project Nevada and i've set up a bunch of dynamic HUD stuff using iHUD and aHUD. And also a bunch of little mods which don't affect the looks.
If you are going to mod, be prepared for headaches at getting it all to work with each other. My whole game is one big jury rigged setup that i'm very surprised is now mostly stable.
