Viva new vegas is really awful. Don't bother. FNV was already a fairly ugly game, but it was at least consistent, which counts for a lot. VNV's eclectic mix of "HD" retextures and weather mods make the game look like one of those early transitional period 3d games from the late 90s, aside from just being actually worse looking than vanilla in many cases. The flora mod is jarringly out of place looking, and dynolod, which i consider a must for games like skyrim, actually works against the game here, because the LOD pop in is somewhat skillfully disguised in vanilla, but here it is sharp and sudden, and much like morrowind, it actually makes the gameworld feel smaller and less mysterious.. Some of the stuff is an improvement, but overall its a huge step back. No seriously - vanilla looks a lot better. Aside from that, the mod is a schizophrenic mix of various UI, balance, item and patch mods. The result is very busy, and not very good. It feels confused. And of course, you will get some retard telling you its all customizable, and yes it is, but that defeats the entire fucking purpose of using someones curated modpack in the first place.
In the end, i literally just reinstalled FNV clean, chucked on jsawyer's original mod and went about business.
