modorganizer VS vivanewvegas-wabbajack

Use a mod manager – pick either Vortex : https://www.nexusmods.com/about/vortex/ Or MO2 : https://www.nexusmods.com/skyrimspecialedition/mods/6194

I'd grab the one from gog-games.to, I can't link directly as that's against the rules. It's compatible with MO2 (Mod Organizer 2) as well as having a version of skse64 (Skyrim Script Extender x64 available for it.

I highly recommend Mod Organizer 2, but Vortex is an acceptable alternative. As a rule of thumb, the more advanced you want to get with your modding, the more strenuously I recommend MO2 as there are some differences in its technical approach that make a bigger and bigger difference as the complexity of your build increases.

I’m not running OBSE by itself. I’m running it alongside Mod Organizer 2. This script will setup MO2 for you and set it so that Steam launches it automatically when you press play. Then, you’ll need to follow this doc to install OBSE alongside MO2. Hopefully that would setup all of your pathing correctly.

MO2 is Mod Organizer 2.

Fallout: New Vegas is great, but I'd strongly advise doing even your first playthrough with a decent Vanilla+ Modlist, it will take an hour or so to set up, but it's so worth it. I could never get past the first 2-3 hours, before I played it with this Modlist. The game already started feeling old when it came out (technology-wise) and this fixes it almost completely.

That’s the thing with Vortex, you can’t manually manage your plugin load order. Some people find it easier for new modders, but I think it’s detrimental to creating a good modlist. I’d recommend looking through Viva New Vegas and possibly consider switching form Vortex to Mod Organizer 2.

I recommend following Viva New Vegas This will tell you how to use MO2, along with making your game be stable and work properly.

Follow Viva New Vegas up until the User Interface Section, then skip to the final steps for the load order.

Grab MO2, install mod with it, learn how to use it here

Follow Viva New Vegas, you need a bunch of prerequisites to make them work correctly and you may as well make your game more stable for 5% more work on the way. Stop after the Gameplay section unless you want the rest of the mods.

For best results ensure you follow a GOOD modding guide as a starting point. For FNV, you absolutely need to follow Viva New Vegas (https://vivanewvegas.github.io/). FO3 and TTW have guides by the same author.

However I do recommend following Viva New Vegas for general bug fixes, if you want a purely vanilla playthrough, stop at the User Interface section of the guide.

If it can run Witcher 3 I doubt it can't also run FNV. If you do get the game make sure to get the performance mods + bugfixes from Viva New Vegas.
