SegmentNextFallout New Vegas Mods: The Best Fixes and Overhauls for PC in 2026
Fallout New Vegas mods are a PC matter. The Xbox 360 and PlayStation 3 releases and the console Ultimate Edition take none, so everything on this page applies to the Steam, GOG and Epic Games Store versions of Fallout New Vegas. The list is grouped by purpose because the order you install in matters more here than in most games: the engine fixes go on first, and the things people search for by name (a texture pack, a quest mod, a sprint key) only behave once those fixes are in place.
Each table names the mod, what it does and why it earns a slot. Mod facts come from the mods' own Nexus Mods pages, from the Viva New Vegas guide maintained by ModdingLinked, and from the 2025 and 2026 lists and articles at PC Gamer, GameSpot, Kotaku and Windows Central. Where those sources disagree with each other, the page says so rather than picking a side quietly.
Stability and engine fixes: install these first
Two files go into the game's root folder before anything else. The New Vegas Script Extender (xNVSE) expands what scripts can do without changing the executable on disk, and the 4GB Patcher lets FalloutNV.exe address up to 4GB of RAM and loads xNVSE automatically, so you keep launching the game from its normal executable. The patcher supports the Steam and GOG builds; the Epic Games Store build needs the separate Epic Games Patcher instead, and neither xNVSE nor the patchers support the Microsoft Store version or the German No Gore edition. Everything below the patcher is an NVSE plugin or a plugin file, and they need xNVSE in place first.
| Mod | What it does | Why it is on the list |
|---|---|---|
| New Vegas Script Extender (xNVSE), xNVSE Team | Extends the game's scripting engine; version 6.4.9 shipped in September 2026, continuing the original NVSE by ianpatt, behippo, scruggsywuggsy the ferret and HLP | A requirement for nearly every mod in the sections below |
| 4GB Patcher, Roy Batty and LuthienAnarion | Makes the executable 4GB aware and auto-loads xNVSE; run FNVpatch.exe once in the root folder and it leaves a FalloutNV_backup.exe behind | The 32-bit engine runs out of memory under textures and plugins without it |
| JIP LN NVSE Plugin, jazzisparis and LuthienAnarion | Adds 1,000-plus script functions, fixes engine bugs and restores broken features; version 57.30, paired with the JIP LN Settings INI | PC Gamer notes it also lets you use the console without losing achievements |
| NVTF - New Vegas Tick Fix, Carxt, Tgspy, lStewieAl and WallSoGB | Fixes micro stutter and the physics problems above 60 fps; Viva New Vegas puts the safe ceiling at roughly 120 fps; needs its own INI | Replaces the old New Vegas Stutter Remover, which the Viva New Vegas guide says now causes periodic crashes |
| Yukichigai Unofficial Patch (YUP), Yukichigai | A bug fix compilation for the base game and the six DLC packs, from Boone's head tracking to the In Shining Armor perk doing nothing | The successor to the community bug fix compilations of 2010 |
| lStewieAl's Tweaks and Engine Fixes, lStewieAl | Configurable quality of life changes and engine fixes, switched on and off from a Tweaks entry on the main menu | Viva New Vegas ships its own INI preset for it, and its Engine Optimizations companion rewrites slow load and save code |
| JohnnyGuitar NVSE, ShowOff xNVSE, kNVSE, UIO | More functions and engine tweaks, an animation framework, and a HUD organizer that keeps several interface mods from fighting | Dependencies for the interface and animation mods further down |
| FNV Mod Limit Fix, Combat Lag Fix, VATS Lag Fix, ActorCause Save Bloat Fix | Raises the file handle limit, removes a framerate drop when attacking an enemy with a visible health bar, cuts a one to two second delay before VATS hit percentages, and shrinks save files by 15 to 30 percent | Small plugins that fix specific, well documented engine bugs |
One name from older lists needs a warning. New Vegas Anti Crash (NVAC) is an NVSE plugin that catches access violation exceptions so the game keeps running, and PC Gamer's list, updated in December 2025, still opens with it. The Viva New Vegas Safe Modding page argues the opposite: its generic null checks let the program carry on when it should not, which the guide links to instability and save corruption, and it can conflict with other NVSE plugins. Windows Central made the wider point in January 2026 that many long-standing New Vegas fixes are now outdated and can make the game worse. If you follow the Viva New Vegas route, leave NVAC out; if you keep it, know that it is the one item in this table the two camps disagree about.
These plugins are the modern answer to the launch-week workarounds on our crashes and freezes page, where the fixes were INI lines such as bUseThreadedAI and iNumHWThreads and renaming .bak save files. YUP in particular is the direct descendant of the fan compilation recorded on our community patches page; its author describes it as a successor to those early bug fix compilations.
Quality of life and interface
The interface was built for a television across a living room, and the mods in this group shrink it, sharpen it and add the menus later games take for granted. The Mod Configuration Menu comes first because several of the others put their settings inside it.
| Mod | What it does | Why it is on the list |
|---|---|---|
| The Mod Configuration Menu and MCM Extender | One in-game menu for configuring mods that support it; the Extender adds script-free menu creation and bug fixes | JAM and other gameplay mods expose their options through it |
| Vanilla UI Plus | Reworks menus and text scaling while keeping the original look | The modern replacement for MTUI, the PC Gamer pick that shrank the console-sized fonts |
| UI Improvements and PipBoy UI Tweaks | Quality of life features and fixes across the menus and the Pip-Boy | Viva New Vegas has you set ExpandedAttributeInfo and ExpandedSkillInfo to 0 in UII_Config.ini to avoid stutter |
| Clean Vanilla HUD and Clean Companion Wheel | HD remakes of the HUD art and the companion wheel icons | Removes the smudged low resolution textures without redesigning anything |
| High Res Local Maps and High Resolution Screens | Raise the resolution of local maps and of the Pip-Boy, terminal and character creation screens to match your display | The Pip-Boy screen otherwise renders at its 2010 size |
| Menu Search, lStewieAl | Ctrl-F searching in the Pip-Boy, container, barter, recipe, level-up perk and save menus | Cuts the scrolling that PC Gamer joked would wear out a mouse wheel |
| JIP Improved Recipe Menu | Rebuilds the crafting menu so recipes are easier to find and use | Pairs with the workbench and reloading bench recipes on our crafting page |
| JAM - Just Assorted Mods | Quick loot menu, dynamic crosshair, hit markers, a weapon wheel and an optional sprint, all configured in the MCM | Viva New Vegas ships a preset with loot menu, crosshair, hit marker, hit indicator and weapon wheel on and sprint off |
| Auto-Save Manager, Faster Sleep-Wait, Better Caravan | Timed autosaves with save slot management, shorter sleep and wait animations, and a usable Caravan table with optionally smarter opponents | Three small fixes for three daily irritations; GameSpot lists the last two as well |
If you only want a sprint key and nothing else from JAM, PC Gamer's pick is Just Vanilla Sprint, which drains Action Points as it runs and needs the kNVSE Animation Plugin and JIP LN installed first. Convenient Fast Travel Markers, from the same list, adds markers for the back and forth quests between two NPCs and a direct return to the Lucky 38 once you have the suite.
Graphics and performance
New Vegas is far more CPU bound than GPU bound, so the performance work happens in plugins and INI settings rather than in the graphics menu; Viva New Vegas rates a quad-core CPU, 8GB of RAM and an SSD as enough for 60 fps at 1080p with its whole list installed. The NVTF INI is where the big switches live: bModifyDirectXBehavior enables its DirectX changes, bUseFlipModel turns on the flip presentation model, and bUseDefaultPoolForTextures lowers RAM use for high resolution textures at the cost of breaking Alt-Tab in exclusive fullscreen, which is why the ModdingLinked performance guide runs the game windowed with bFullScreen=0 and OneTweak for a borderless window. For a CPU-limited machine the same guide adds DXVK, which translates Direct3D 9 to Vulkan and cuts draw call overhead. The older INI knobs, iFPSClamp, uGridsToLoad and the interior and exterior cell buffers, are explained on our tweaks page.
| Mod | What it does | Why it is on the list |
|---|---|---|
| NVTF INI, Cell Offset Generator, zlib Updated, lStewieAl's Engine Optimizations | Stutter and DirectX fixes, cell offsets generated at startup to remove loading hitches, a faster compression library, and rewritten load and save code | The performance layer that texture mods sit on top of |
| DXVK and OneTweak | Direct3D 9 to Vulkan translation, and a borderless window in place of exclusive fullscreen | Fixes the Alt-Tab freeze Windows Central still complains about and helps CPU-bound systems |
| Sunshine On My Shoulders | A weather overhaul that stays close to the original palette, with extensive configuration | The Viva New Vegas weather pick; Nevada Skies, on the GameSpot and PCGamesN lists, changes the look far more |
| Atmospheric Lighting Tweaks and Vanilla Plus Tonemapper | Reworked interior lighting, and a tonemapper that stops bright areas blowing out | Lighting changes that do not need an ENB |
| Simple Character Expansions | New face models for more than 170 NPCs | The Viva New Vegas alternative to Fallout Character Overhaul, which the Safe Modding page says has broken file paths that cause pink textures |
| Cloud Upgrade NVSE, 3D Rain, Climate Control - Rain | Moving cloud layers, volumetric rain, and fixed rain triggers with new audio and textures | Weather effects the 2010 engine never had |
| Anniversary Anim Pack, B42 Weapon Inertia, B42 Optics | Reanimated weapons, weapon sway with momentum, and picture-in-picture scopes | The first-person feel is where the game shows its age most |
| NMC's Texture Pack | Retextures roads, trees, buildings, vehicles and objects, leaving sky, water, characters and weapons alone, in three quality tiers | The texture pack on the PC Gamer, GameSpot and PCGamesN lists; pick the lower tier if VRAM is short |
Two things to skip. ENB presets for New Vegas were never finished and have been abandoned by ENB's author according to the Safe Modding page, which also notes they require MSAA off and break when engine-level graphics plugins change; ReShade or New Vegas Reloaded are its suggested alternatives. Fallout Character Overhaul is covered in the table above. Both still appear on older lists, which is the reason to check a mod's last update date before installing it.
Content overhauls and quest mods
Viva New Vegas keeps its content picks to a modular Extended section and stays close to the original design; the big quest mods on the press lists sit outside it and need a new character and a compatibility check.
| Mod | What it does | Why it is on the list |
|---|---|---|
| Tale of Two Wastelands | A total conversion that runs Fallout 3 and its DLC inside the New Vegas engine so you can travel between the Capital Wasteland and the Mojave | The largest project in the scene; PC Gamer's pick despite noting it is incompatible with some other mods |
| New Vegas Bounties I, II and III, someguy2000 | Fully voiced bounty hunting across the Mojave against rogue rangers, Fiends and other outlaws; the first part dates from November 2010 | On the PC Gamer, GameSpot and PCGamesN lists; the Someguy Series master file it needs also unlocks The Inheritance, Russell and The Better Angels |
| The Living Desert | Hundreds of new NPCs and scripted events across the map | The Viva New Vegas world population pick |
| Better Brotherhood and Goodies | More ways to earn Brotherhood fame with fixed ending conditions and a new weapon; restored cut content, consistency fixes and delayed DLC items | Content that reads as if it shipped in the game |
| JSawyer Ultimate Edition or Agua Fria - JSawyer Redone | Rebalances based on director Josh Sawyer's own mod: lower starting health and carry weight, slower leveling, a lower level cap and weighted ammunition | PC Gamer lists Ultimate; Viva New Vegas Extended uses Agua Fria and says it is not for a first playthrough |
| Brave New World | New professional voices for 145 characters, with an optional set of new faces | PC Gamer's answer to hearing one NCR voice actor everywhere |
Tale of Two Wastelands is not hosted on Nexus Mods. The installer comes from mod.pub, needs English copies of both Fallout 3 and New Vegas with all their DLC on Steam, GOG or the Epic Games Store (the two games can come from different stores), and writes a 17GB mod folder; The Best of Times guide, the written install guide the TTW forum recommends, asks for 40GB free including both games and reports the installer's audio encoding taking around 40 minutes on a Ryzen 5 5600X. It also ships its own patch, YUPTTW, in place of YUP, and adds a TTW NVSE plugin as a hard requirement.
Two famous names are left out of the table on purpose. Project Nevada, by the team behind Fallout 3 Wanderers Edition, is a set of modules (sprint, bullet time, a dynamic crosshair, a grenade hotkey) whose Nexus page shows version 2.5 and a last update of February 7, 2012. GameSpot and PCGamesN still recommend it; the Viva New Vegas Safe Modding page calls it outdated, inefficient and bloated and says its chargeable weapons, lethal headshots and stealth and AI changes either fail or break the game, pointing players at separate mods such as JAM for the same features. The Frontier, a total conversion set in Portland, Oregon, released in January 2021 after seven years of work and was pulled from Nexus Mods by its own team within two weeks. Game Informer and GameSpot reported the reasons at the time: a team member had posted inappropriate content involving anthropomorphic minors on a personal art page, and the mod itself drew criticism for content including a storyline that let the player make a character their slave. It returned with that material cut. It is playable, but it is a controversy first and a recommendation second, and both articles are worth reading before you commit a save to it.
Install order and load order basics
Viva New Vegas is built in a fixed sequence, and the sequence is the install order for this page whether or not you follow the guide to the letter.
- Prepare Windows: install the current Visual C++ redistributables (both the x86 and x64 versions), disable Base Address Randomization for the 32-bit game, and install the game outside Program Files.
- Root folder: extract xNVSE into the game folder, then run the 4GB Patcher (or the Epic Games Patcher). Verifying files through Steam or GOG later undoes the patch, so re-run it after any verification.
- Mod manager: install Mod Organizer 2 and create a portable instance for New Vegas.
- Utilities: the NVSE plugins (JIP LN, JohnnyGuitar, ShowOff, NVTF, kNVSE, UIO, Mod Limit Fix) with their INI files.
- Bug fixes: YUP, Unofficial Patch NVSE Plus, lStewieAl's Tweaks, the lag fixes and the mesh fix packs.
- Interface, then content, then gameplay, then visuals, in that order, each behind its own separator in the mod list.
- Load order: download the guide's loadorder.txt into the MO2 profile folder and check the Plugins tab against it; if the two differ, sort by the Priority column. Master files (.esm) such as someguyseries.esm sit with the other masters.
- Start a new character. The guide's FAQ is blunt that an existing save cannot be carried over.
For anything you add beyond a guide, the Safe Modding page gives the rules that matter: read the description and requirements, add a few mods at a time, use FNVEdit to look for record conflicts, and troubleshoot by disabling half your mods and halving again until the culprit is isolated. It warns against letting LOOT sort the load order for you, because its masterlists for New Vegas are often outdated or incomplete, and against automated plugin merging tools, which can break complex mods. Wrye Bash patches get a conditional pass, only if you are willing to read through the patch they produce.
How to install: Mod Organizer 2 or Vortex
Mod Organizer 2 started as Tannin's project and is now maintained by the community. It installs mods into a virtual file system (USVFS), so the game's Data folder stays untouched, mods can be enabled, disabled and reordered by dragging, and separate profiles can hold different mod lists, saves and settings. The trade-offs are that mods are only visible to programs launched from inside MO2, a heavy loose-file setup carries some overhead, and antivirus software sometimes flags the hooking it relies on. Viva New Vegas, The Best of Times and the TTW forum's own advice to newcomers all use it.
Vortex is Nexus Mods' own manager. It supports several hundred games, has one-click installs and collections, built-in load order sorting and profiles, and it does handle New Vegas. PC Gamer says either manager will do for its list, with one catch specific to this game: in Vortex you must enable archive invalidation, found under Settings then Workarounds and sometimes labeled BSA redirection, or texture and mesh replacers will not show up. The TTW forum's regulars steer new users toward MO2 instead, and Viva New Vegas is written for MO2 only.
As for guides, the press converged on one in 2026. Kotaku's January 2026 best way to play piece calls Viva New Vegas a very handy guide and the best way to play the game on PC, and Windows Central's PSA the same month calls the community-written guide a must in 2026, adding that it also works on Steam Deck according to Kotaku. Set aside an hour or two, read every step, and treat the lists above as the map of what the guide is about to install and why.
