Long loading times.

[Nifference22]

I don't have a lot of mods installed but most times when I enter or exit a building, the screen goes black and takes 2-4 minutes to load. I have 21 active mods at the time of making this and I plan on downloading more, (via vortex), so I'm not sure what's causing it. Can anyone help fix it or help it? Anything helps.

depends on the number of objects, scripts, references, per cell cluster, load times are hardcore for boston downtown but less for wilderness, texture size is also important

The more loose file mods you have, the longer it takes cells to load while the needed previously unread loose files are read by the game.

I don't mind this as it means the game isn't loading everything at startup and only loads them as needed.

Try crossing the cell boundary several times. If it gets faster after the first slow load, then that's what's happening, and it's (in my opinion) no big deal. It's efficient.

In summary, a slow loading time crossing a cell once is just the game reading loose files.

If you have slow loading times crossing the cell boundary more than once, then it's something else.

I had the same problem. I fixed it by installing High FPS Physics Fix: https://www.nexusmods.com/fallout4/mods/44798 . After I unlocked the frame rate, it was set to 60 fps, the load times now are a fraction of what they were. Minutes to seconds.

This.

Fallout can't really handle SSD's verry well. Use load accellerator mod if you have SSD. It temporary unlocks the FPS (60 is pretty mandatory during normal gameplay).

loading times can vary if your fps are lowered below 60 fps. for example because of a power saving setting.  check that your fps are at stable 60 fps during loading.

independently from the fps-influence - loading to different places can make a huge difference in actual loading time as stated by Qrsr

No,no,no. If you have SSD's you do NOT want your fps to be a stable 60fps during loading. This is exactly what the load accelerator does. It lets go of the restriction which is preventing the engine from loading faster & restores the 60fps after loading. (check the mod page for the technicalities)

Load Accelerator by chairo_hippo:

Reduce the loading time by controlling vsync(fps) and CPU affinity at loading screen.
This is expected to shorten the loading time under the SSD environment.
(Under HDD environment does not seem to have much effect)

CAUTION: If you uncap FPS it can wear down your hardware, e.g. your GPU or iGPU. I would play around with max. FPS cap. 120 FPS may already result in far better loading times.

 

Again, having optimized texture packs can have a HUGE influence as well. Since the game will load the interior exterior cell objects based on uGrid settings more or less. Thus, external worldspace have much higher load times compared to internal worldspace since most interiors are smaller cells with some exceptions. Optimized textures will recude the size of the cell itself, you can see the total texture size in the CK:

EDIT: Having a cell far below 177 MB with high quality texture is the way to go ...

Also moving from exterior to interior worldspace may also result in higher loading times if the uGrid is full of high texture environment since the game unloads all of this when transition (exterior to interior) applies.

I remember scripts also influence all this, and scripts are also tied to FPS. I remember people were talking about broken scripts in vanilla which may also cause some issues when loading certain environment.

EDIT2: The game can also cause issue IF you use the "auto-save" function, e.g. save when sleeping is an auto-save or when transition applies, or you close your game. If you use this save (e.g. load the save), and play further it may cause issues. I had this once and its was 100% tied to auto-save. Although it is rare.

i play fo4 with a 100 fps setting and it loads faster as with a "steady" 60fps setting (same save, tested), physics fix mod installed. loading times get really worse below 40 fps in my setup. i deactivated autosave.
