Modding New Vegas via Steam Play/Proton [LInux]

[aristocat]

I've gotten New Vegas to run flawlessly with perfect performance through Steam Play versus running the GOG version in traditional Wine 3.17 with not-as-perfect performance. Of course there was always going to be a catch: I'm finding it difficult to figure out how to get mods (think FOMM or Nexus Mods) to work with the Proton prefix.

Has anyone figured out how to go all nine yards and get mods working via Steam Play, or am I better off trying to continue tinkering with the GOG version and pray I could get better performance out of it?

It works just fine like in Windows. You just mod stuff and launch the game.

I have used Wrye Flash NV to manage mods. In my opinion it is great. You probs could add that program to your Steam library, but I used Wine to launch Wrye Flash NV, modded stuff, and then launched the game with Steam Proton. Works great.

Could you make a guide as to how to load something into the Proton prefix?

This may be two years too late, but I spent the night looking into this and figured it out, and this thread is one of the first results on Google.

The easiest way to do this is to first install NVSE, using their instructions.
Then, for any other mods, use Vortex.
- To install, use Lutris. find it in Lutris online, just search "Lutris Vortex Mod" and install as recommended, may take a while as it deals with dependencies and the like. When I say "as recommended", I mean that exactly. Iirc, it instructs you to disconnect from the internet, launch vortex, and disable auto-updates or something, but it was a very detailed prompt, just listen to what it says to do.
-- Lutris is very easy to install, and if you have issues/error messages 90% of the time if they don't break anything you're fine, but a reboot can't hurt.
- Once installed, go to settings>games and change the save path (you'll have to choose My Computer, Z: Drive, and then wherever your steam library is, down to \steamapps\common)
- Go to games, and hit the scan button (full just this once). Then go to Discovered, hover over the game, and hit "manage". This'll add the game.
- Also, make or use an empty folder literally anywhere on the same drive those games are saved to, and then go to Settings>Mods and change the staging folder location, as by default you'll get all kinds of errors when Vortex can't link the mods to the games. I just made a folder in the same directory as my steamlibrary and called it a day.
- Then, don't use the "mod manager install" option. Supposedly it works for some people, somewhere, but idk. Instead, download the mod manually, and DO NOT extract it. Just "show in folder" or go to downloads and find the actual .zip .tar or .rar or whatever. In vortex, go to "mods", and you'll see a big "Drop files here" area at the bottom of the page, and you'll do just that.
-- If you have everything above set up, then all you have to do is hit install, and then choose to "enable" and it should deploy automatically, but if it prompts anyways, just hit deploy. Don't ignore errors here, if it says something's wrong it probably is.
EX: if it says "[exorbitant amount of] files failed to deploy", check the mod staging folder, as you probably skipped that step. The staging folder HAS to be on the same drive (as in drive letter in Wine) as the game installation.
- Also, I got another error for certain mods saying they were "missing parents" or something, for the same reason. It couldn't find the game, but for some reason the specific verbage of the error listed that it couldn't find each of the dlcs' .esm files. I literally only had a problem with the staging folder, that's it.

Anything else, like redundant mods/boot order, that's between you, the mod creator and God.
