NVSE VS vivanewvegas-wabbajack

xNVSE 6.3.0 - https://github.com/xNVSE/NVSE/releases/

old NVSE or the newer xNVSE ?

I'm mostly looking to run xNVSE for the stutter fix. I've downloaded the newest version of xNVSE (6.3.0 from https://github.com/xNVSE/NVSE/releases)

His video recommended using the New Vegas Script Extender (NVSE) v5.0 (which is now outdated it seems) and so I went ahead and installed it, and it ran well until mods further along in his video needed the newer xNVSE 6.2.6 - 6.3.0 version. My issue arises when it comes to uninstalling v5.0 and doing it correctly. I would then need to install the new version correctly also... I am new to modding and trying not to break the game. Any help would be greatly appreciated!

That usually means a mod error. Check the requirements. I think the new update of one of those mods requires an updated xnvse.

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.
