Make sure the Viva New Vegas profile is active before proceeding.
nvse_steam_loader.dll is still needed with the GOG version of the game.
- An updated version of NVSE, which extends the scripting capabilities of the engine and is essential for most mods
This mod is still needed with the GOG version of the game for the NVSE integration.
- Makes the game large address aware, meaning it can use 4GB of RAM instead of 2GB
From now on, you should run the game through the New Vegas option in MO2, rather than the NVSE option. This mod makes the game auto-load NVSE when you run the game through the default executable, which is generally the safer option.
If you have an older CPU (pre-2013), use the Main File - NVHR - SSE2 2.4 instead.
- Replaces the game's heap management system with a much faster hand-written version, which can lead to large performance gains
If you do not know what these instructions mean, or how to install mods with MO2, read the Mod Installation Advice section from the MO2 page
- NVSE extension with 800+ new functions and many engine bug fixes
After installing a mod, make sure you check the box next to it in the left pane of MO2 to enable it.
- Another NVSE extension similar to JIP LN
- Works to greatly reduce the rate of game crashes
If you do not know what to do when installing multiple mods from the same page, read the Mod Installation Advice section from the MO2 page
- Works to fix micro-stuttering, improve performance, and allow playing at higher framerates
In order for this mod to work properly, make sure you installed the DirectX and VC++ requirements from the Introduction page
- Raises the game's plugin limit to 255 and improves performance/load times, even if you are far below the plugin limit
Although this mod is on the Skyrim Nexus, it will still work fine for New Vegas provided you follow the installation instructions. If you plan on playing in windowed mode, you should skip this mod.
Fallout New Vegas\Data\NVSE\Plugins\
- Enables borderless windowed mode for safe alt-tabbing
- Adds Ctrl+V as a hotkey to paste into the in-game console, along with a few other helpful shortcuts
In some rare cases, Mod Organizer 2 has issues handling .DLL files and they won't load in-game. If you can not get any of the mods in this section to work per the following instructions, then you should try installing the mods directly into the game's Data folder rather than through MO2. The files from the mods should end up in
Fallout New Vegas\Data\NVSE\plugins(the same folder as the files from OneTweak).
