Long Fallout 4 Loading Time


Recommended Posts

Posted

So I've been investigating the long loading times for Fallout 4. In particular the initial load, which often takes a full minute for me, before I see the main menu. I tried removing the CreationClub stuff and that helped some (a couple of seconds). But I've decided to dig a bit deeper into things. I ran Fallout 4 with the performance monitor up and running and noticed something interesting. Namely, for the full minute that it was loading the game, it was reading the 'Fallout4 - Interface.ba2' file at about 20x the rate than any other file. And that's interesting, because the file itself is only 200 MB. It should load pretty quickly on my rig.. And for the first 10 seconds, it was running at 25MB/second. So that means it must have loaded the entire file. Yet it takes another 50 seconds where it's reading from the file at 3-10 MB/s.

So I tried to disable the load copies I have (e.g. the Strings folder, the Interface folder and the Programs folders) thinking it might be comparing files because I set Fo to load external files. My guess is that the load issues is somewhere in that setting. The next I will try is to disable loading external files and see if that helps the situation somewhat.

 

It's a bit annoying to have to wait a full minute for fallout to start up, when I have an expensive SSD running it, so any tips are welcome.

it is hard to say.

A while ago in my game of Fallout 4, it had really long load times

so I did the tests to find out that it was the voices folder inside the sound folder that was the problem

because of mods such as Boston Breeder(biggest offender), outcasts, Fusion city and a couple of others.

 

so afterward I started packing a good chunk of my loose files into BA2's (starting with sounds)

 

however about those performance monitor,

I wouldn't look at the current workload but the logs

because the program might not be able to keep up with the game so it might give you the wrong info

 

now my problem is really long savegame loading times.

last night for instance, in the time of loading a save game, I filled two 1-liter water bottles with a water purifier.

@Reginald_001 I've poked around my own system too as Fallout 4's on my SSD, but I've got my mods installed to another HDD, so I expected [and got] longer load times and startup, but it's much longer than it really should be. As in a good 5 minutes, with the mods I've got, compared to 30sec-1min with a minimal AAF setup.

SysInternals Process Explorer is my go-to, outside of the MS PerfMon. At one point, I had an entire second Fallout4.exe instance that wasn't visible in Task Manager, chewing a good gig+ of my RAM alone, that wasn't related to the running-game instance I had up. That was weird.

That aside;
You usin MO2?

 

Disclaimer: The following may or may not be complete bullshit, so don't take it as Factâ„¢.

I assume some of the delay is the sheer amount of memory usage and hard faults it pulls as it tries to load everything with mods. I'd guess that some of it is also how the game operates when it runs into a change or link out of the *.ba2. Cause it sure sounds like it's either re-reading the entire *.ba2 after it first read it, or it's reading/parsing all changes after the initial read.

Another one that I found was a long loading time for the BloodSprayGray_D.dds file, which is part of the enhanced blood/gore effects mod. I had disabled it a long time ago, but some of the textures were still there. I removed them and that might have shaved off a few milliseconds here and there. I've also been looking at network. As it seemed initially to be some kind of network time out.

two things

1. maybe post your load order, that might be helpful

2. with your mod companion Ivy, are the voice file are Loose files or in a BA2? (because I like it and I put the voices into a ba2 on my ba2 binge)

No they aren't. But they don't show up in the perf log as being a long loading time. It's all centered around Interface.Ba2.

I've been trying on a clean install to rule out any issues with mods or loose files, same long loading times.

I'll have to test it at some point with the base FO4, but I see what you mean. Had PerfMon open and watchin, and saw it at over 202MB/s, as it plummeted to ~3.6MB/s for the duration.
Could easily be an engine issue we're stuck with, but we'll see.

Actually, you on Windows 10?
Most of my start-up delay now that the replacement RAM's arrived, has been from MsMpEng.exe [Microsoft's 'malware protection engine, aka Windows Defender -_-].
Namely that it basically doubles the damn read time, cause it needs to check everything before it'll let it run/load.

I excluded f04 first thing. Thise cpu cycles arent real cycles. It just moved into a virtual space so it looks like a lot of overhead that isnt actually there. Disabling it did not shave off loading time for me.

I understand loader loading times when the game is up but fallout 4 always seems to take forever to even start and I have a great computer too.
