Im looking for some mods for fallout new vegas the type of mods i usually enjoy are the crazy wacky mods like When world's collide. I also enjoy mods like Beyond Boulder dome where they have long quest lines and new world spaces to explore.
*The first thing I recommend is to apply the ifpsclamp=60 fix into you INI (easily Googled).
The game has major, major stutter otherwise and none of the stutter fixes help much. You MUST have your quality settings so you don't fall below the refresh rate (i.e. 60FPS) or else there are major synch issues.
(The same applies to Fallout 3, however you should also apply the 2-core fix for F3 if you have more than two cores.)
I think you'd be better off just sticking with NEXUSMODS which I assume you use.
