Looking at the script from the repo you installed 6.2.4. This isn't the most recent. I think you'd be fine to update (it's just extracting an exe and a couple dolls to your game directory). I've never heard of a mod requiring an older version, so staying with the most recent is probably good practice!

I definitely recommend weapon inertia and the one that makes enemies react to getting shot (can't remember the name, ragdoll maybe?). They're subtle changes but make a huge difference in how the game feels!
For a long time I went down crazy modding rabbit holes for the fallout games, spending more time modding than actually playing. I finally decided to just pick a setup and stick with it so I could actually enjoy the game. I ended up following this guy's modlist which has a nice focus on the essentials.
Yeah, I mean being able to boot either into proxmox or windows. But in proxmox, I can also open that windows install as a VM.
Some details on how it should work are here (apologies for the reddit link): https://www.reddit.com/r/VFIO/comments/aejdqk/kvm_importuse_existing_windows_install_on_disk/edqtmvb/
Yup, that's pretty much it! I haven't figured out the specifics of setting it up beyond the fact that it's possible. If it proves too complicated, I suppose it's not too much harder to just maintain separate drives for Windows VMs and dual booting, since I won't ever use it for anything other than games.
I'm in the planning stages of a build that will be essentially this, a proxmox build that'll include my NAS with several hard drives (running in one VM), all my docker containers (another VM) and Linux and Windows vms with passthrough that I can spin up temporarily for games.
I think I can get the Windows VM in a place where I can also restart the whole machine and boot in natively, as a fallback for games with aggressive anti cheats that won't allow VMs, which I don't think I'll be playing much of anyway.
To answer your question, it really would be best to check game by game if the anti cheat allows VMs.
I definitely won't dispute that Viva New Vegas is a gold standard, but with the number of mods that even the base setup pulls in I wouldn't really call it minimal. I think the person who was asking (and me, the last time I played NV) just wanted a simple set of mods that did the most to improve the experience, which I think that list accomplished better than the others I'd looked at.
Apart from ENB, do you know what the other problems are? I'd guess mostly the result of it being a few years out of date, but genuinely curious!
