Im currently testing mods with a test play-through. After installing Drag's mods the game crashes in a few seconds. I tried starting a new game, but its SUPER laggy when I look at Doc Mitchell(whos been modded by Drag) then it crashes. I am using Mod Manager 2, so Im curious as to what I have to do to make these mods run smoothly. Im certain there is a way, I just dont know what it is.

Spoiler:

 

I downloaded them all, and installed them using the "install mod from archive" button. Not sure if thats what I was supposed to do.

Did you try Vortex? It has a fairly ok autosort option, maybe the issue lies in a load order. I run a whole bunch of Drag's mods and no issues whatsoever. I'm not saying it's MM's fault but I've read a lot of a bad things about it so maybe there is some truth in it. Just a few thoughts from a greenie

Vortex isn't even playing in the same league as MO2, so the issue is definitely something else.

Can I see an actual loadorder? Because if the loadorder matches the install order I'm seeing in the pic it's definitely not sorted. For starters, the MCM Bugfix is literally flagged as redundant, which means that it's most likely overwritten by the mod it's supposed to fix. And if the DLCs are loaded in the order they are installed, that's also not how it's supposed to be.

Plus, the game really needs the LAA patch, especially with large texture mods. Even if the GOG version is used, which already is LAA patched, running the patcher so NVSE can detect the changes is pretty much mandatory.

And finally, any INI tweaks need to be done with the MO2 ini editor so the Profile inis get edited and not the ones the game generates.

In short, a full list of installed mods plus the actual loadorder will help a lot in troubleshooting the issue.

Post your full load order, mods installed on Mod Organizer 2 and you specs, them we can talk.

sounds pretty simple to me, you have OOM's Out Of Memory errors.
Check your NVAC.log file if i'm right.

If so, you hit your memory limit, then you might try to use ENB to make sure the game can use more RAM.

I've never had a problem running dragbody's overhauls so long as I'm also using the 4gb patcher. Though I use an old version of it that uses its own exe instead of patching the default one.
