How to Install Mods - Fallout: New Vegas
Aug 18, 2014 mcm installation menu says the same thing, nvse not detected. I uninstall nvse and try to reinstall it, go back to mcm/flashlight, and they keep telling me they aren't detected. I got the mcm and flashlight to 'detect' nvse now. Project Nevada, oHUD and HUDExtended are all working for me as well. Krux, I downloaded and tried the.
Fallout NV isn’t the easiest game to mod, but we have troubleshot and done our best to provide a bug-free mod list. Follow these instructions and Fallout NV should work (mostly) fine:
- Install Fallout NV (including DLC).
- Install Nexus Mod Manager and direct it to your Fallout NV folder if it does not detect it automatically.
- Download the mods and patches listed below, links will link to the mod pages.
- Install the mods. When installing updates to mods (or multi-part mods) and NMM asks if you would like upgrade to the new mod, select “no” and then select “yes to all” to have the update overwrite the original mod files, if there are any conflicting files.
- Follow this mod install order. If asked to overwrite something, say “yes to all.”
NVSE (Just extract it and place the files in the game directory)
4GBFNV-1-9 (Place in game directory if it pops up with an error)
Project Ultimatum (This is the 9.7 update)
Fallout Character Overhaul - v2.1 (Some options may cause crashing, it is suggested to only check eye and hair texture boxes, along with a teeth texture. Be sure that bLoadFaceGenHeadEGTFiles=1 in FalloutPrefs.ini.)
Interior Lighting Overhaul - Interior Lighting OVerhaul 6-7 (It is suggested to only check the A World of Pain box)
ENB (These cannot be installed by NMM and must be done manually, there are instruction on the ENB’s pages. There are multiple ENBs we recommend, 1, 2, 3)
Note: Nexus Mod Manager integrates a load order program called BOSS and will automatically sort your Fallout NV mods. To launch Fallout NV, use the 4GB Enabler .exe file. The new .exe can be configured to be launched via NMM.
Troubleshooting Fallout NV Bugs, Crashes, & Fixes
Luckily, Fallout: New Vegas is fairly stable compared to Fallout 3, though it does still have problems. The major ones are covered here.
Freezing or crashing randomly - This is usually due to Fallout only being able to properly use two threads at most. Follow these steps:
Open the folder My documents / My Games / FalloutNV
Edit the file FALLOUT.ini.
Inside FALLOUT.ini look for a group called [general].
Inside the general group, after all the configuration parameters, change bUseThreadedAI=0 to 1 and after it add iNUMHWThreads=2
- Now save and close the .ini file and try playing.
Crashing at start of game -
Run Fallout NV in different compatibility modes.
Or
Try running without mods or DLC. If it crashes reinstall/verify game files via Steam, if not, continue.
Disable all mods and run Fallout 3 with the DLC. If it still crashes, try enabling DLC one-by-one to see if one of them is causing the problem. If not, continue.
If disabling mods fixed the crashing, enable half of the mods and see if the crashes persist.
Keep halving the mods activated until you learn which mod is causing the problem.
Reinstall that mod.
If that does not solve the crashes, either ensure you have installed compatibility mods needed for that mod or uninstall the suspect mod completely.

Random Crashes - This can be due to a number of root causes. While I haven’t had any issues, it is possible others will experience instability. Try installing CASM or try these steps:
Open the folder My documents / My Games / FalloutNV
Open the file FALLOUT.ini to edit it.

Use ctrl-F and search “bUseThreadedAI”.
Change that line to say bUseThreadedAI=1 instead, and then add iNumHWThreads=2 on the line below it.
- Now save and close the .ini file and try playing.
(This limits the number of threads Fallout NV can use, since natively it will use too many threads and crash).
Or
Try the same steps as for crashing at start of game.
There are big red boxes with explanation marks - this is due to missing textures. Follow these steps to solve:
Disable all mods and run Fallout 3 with the DLC, if there are still red boxes reinstall Fallout NV/verify game files via Steam.
If disabling mods fixed the boxes. Enable half of the mods and see if the boxes persist.
Keep halving the mods activated until you learn which mod is causing the problem.
Reinstall that mod.
If that does not solve the boxes issue, either ensure you have installed compatibility mods needed for that mod or uninstall the suspect mod.
There are borders around Fallout: New Vegas even though it is full screen - Alt-Tab or alt-enter. It will expand Fallout NV to fullscreen but not actually bring you to another window.
If you have any further issues, please put them in the comments and we will help you solve them.

Tips & Conclusion
- Press the ` key and type in “TCL” if you get stuck somewhere. That will disable collision and allow you to walk through anything. Type “TCL” again to enable collision.
- For AMD GPUs, you can use RadeonPro to force HBAO, SSAA, SweetFX, and more by linking it to the 4GB launcher. NVidia users can use GeForce Experience and the nVidia Control Panel to do this.
- If a type of AA, tessellation, or anisotropic filtering is being forced through either of the programs above, turn it off in game.
- If using an ENB, do not force AA, tessellation, or anything through drivers or other software.
Our collection of mods is certainly not all-encompassing -- in fact, it’s far from it. We didn't want to have too many files in the install list unless needed, so some mods were cut out. If you know of any good mods we didn’t mention, feel free to post them in the comments below! This mod overhaul takes a somewhat old game and renovates it to be a good-looking, fun, and challenging new experience. The post-apocalyptic, desert wasteland in Fallout: New Vegas is an incredibly unique experience to play through, and with mods, it’s worth exploring all over again.

I know, it’s a pretty big claim. First, let’s go over the environment variables, then let’s proceed from there.
I run Linux Mint 18.3 (64 bit) with Cinnamon desktop. In theory, this means it should work for just about any Debian-based distros including Ubuntu.
NVidia 1050Ti running Driver 396.54. Will test with the newer 415.13 later
I’ve got an 8 core 3.5GHz AM3+ Proc with 16 GB RAM, so pretty beefy. This might be helping with some of the stutter issues.
I am currently using the Proton 3.16-4 Beta, however I’ve also done this in the Proton 3.7-8 stable as well.
I also use PPA’s to keep up with the latest stable for Mono, Python, and my video drivers, which tend to be a common source of issues. If these steps don’t work for you, first try updating Mono and Python and make sure your video drivers are up to date and see if that doesn’t fix your problem.
As always, this is an experimental situation, and there is the possibility that this could scrag your entire F: NV install. While using Verify Integrity should fix anything that this could possibly cause, there remains a remote chance that something could go completely off the chain. You assume all liability for any damages caused by following these steps. Here, there be dragons.
Setting Up The Environment
First, let’s make sure we are on the same page as far as the version of 4GB and NVSE.
I use the FNV 4GB Patcher. Do not use the depreciated version, or any of the other versions which are floating around.
I also get NVSE straight from http://nvse.silverlock.org/.
I am also going to assume you have legally purchased a copy of F: NV and have it in your Steam library.
Under Steam Settings, go down to Steam Play tab, and check the box for Enable Steam Play For All Titles
Install F: NV through Steam as per normal. Run it once, and set up your graphical options. Do this *BEFORE* you start getting the FNV4GB and NVSE going.
Setting Up Large Address Aware
For this step, you WILL need WINE, because the 4GB Patcher needs to be run separately. Fortunately, this only needs to be done once. As the name implies, it patches your FalloutNV.exe file. Unzip the FalloutNVPatch.exe file into your /.steam/steam/steamapps/common/Fallout New Vegas (or wherever Steam put your install) folder. Not the Data folder, the one with FalloutNV.exe in it.
Run FalloutNVPatch.exe via WINE. If it gives you an error, run it a second time. You should now have a FalloutNV_backup.exe file in your folder. If you do, then congratulations, you have successfully accomplished this step.
Setting up NVSE
This is actually really simple. Just extract the contents of the folder within the zip file you downloaded into your Fallout New Vegas folder. The one we just ran the 4GB Patcher in.
Use WINE to run nvse_loader.exe. You may have to do it twice to get it to work. It should basically boot up Fallout: New Vegas.
Hit the Tilde key (`) to bring up the command interface and type in GetNVSEVersion and it should return with the version of NVSE. Now quit Fallout: New Vegas.
Run Fallout: New Vegas from your steam library. As is, no modifications, no additional command arguments, just run it like you were trying to run a vanilla instance.
Try that command again. Did it work? Awesome!
In Conclusion
This may not work for everyone. I use Mint because it seems to be one of the most commonly supported Linux distros while also being very user-friendly. The key things here is that you WILL still need to use WINE in the initial setup to run the 4GB Patch and nvse_loader, but you should only need to do that once. After that, it should not be any additional problem over trying to get F: NV to run in Steam Play itself.
I have not yet tested any actual mods dependent upon NVSE (although I plan on running NVAC and NVSR later… heck, NVSR may actually fix the stuttering and FPS drops that many people have been experiencing with the vanilla attempts).
I also don’t think there is going to be a way to run a mod organizer without relying on WINE (unless someone wants to compile a version of FOMM for native Linux compatibility?), which might be a bit tricky when installing mods (especially complex ones like Project Nevada or AWOP).
But for now? It seems to be working, at least for me. Hopefully, others may find this information useful.
