Fallout 4 lag after the migration from NMM

[lynx64]

Hello. Not so far ago I've managed to transfer all the mods for Fallout 4 and FNV from NMM to Vortex. After this FNV works fine, but F4 CTDs after several seconds after game start. Moreover, the game lags pretty much before crashing and some of my game preferences (for example the game fonts colors) were reset. Please help me with identifying the source of this problem.

BTW I've not tried to re-install the F4 yet.

OS I use: Win7 x64. Vortex version with which this problem appeared: 1.7.8. F4 is latest available Steam version, so is the FNV. Mods I use with F4: about a dozen of some additional lore-friendly weapons (can't bring exact mods names and versions due to latest problem with update and Win7 compartibility) such as M60 MG, AR-15 and some other weapons from F3 and FNV.

For Fallout 4 you should verify the base game files. You can do that through Vortex. Or if you bought your game through Steam, then you can do that through the Steam client. If missing or broken files are found let Vortex/Steam install/repair them before trying to launch the game again.

 

If all the game files verify (or after the files are restored), there are other problems that can cause the game to crash.

 

Mods that break pre-combines are a likely culprit. Fallout 4 makes much more extensive use of pre-combines than earlier Bethesda games like FNV. That's because they enable a wide range of devices to run a game with extensive visual details (objects) efficiently. Examples of mods that break pre-combines include settlement location overhauls or scrapping mods that let you delete anything you want.

 

Mod authors have created mods that fix pre-combines that you can add to your list of active mods that attempt to fix this problem. Some of them also provide guides for doing that work yourself if that interests you.

 

For other causes of CTD with Fallout 4, I suggest that you search 'Fallout 4 CTD' or something like that to find out some of the more common issues.

 

If you can afford it and if your PC can handle it, you should consider upgrading to at least Windows 10 since Windows 7 is no longer supported.
