[SOLVED] Silly question but is there a potential fix for fps dropping from 144 fps to 27 fps regardless of area, interior or exterior? Do I have too many mods? Is it a texture problem?

[💦Oshawott💦]

Hello y'all probably a noob question but as I start the game I get smooth 144 fps; however, over time, say around 20 mins, my fps would drop exponentially to as bad as 27 fps. It doesn't matter which area I am in, it occurs in interiors and exteriors. This sounds like a memory leak issue but I am not too sure. Do I have plain too many mods (175 active), or is it a specific mod I downloaded?

I tried posting this in r/FalloutMods but I think I got caught in the moderator web and they haven't approved it yet :pensive:

For reference I have 32 gb ddr5 6900 xt

Cut down on mods to 25.

[Razör]

I crank my game to 700+ mods without issue. Judging by your load/plugin order, it seems you install stuff all over the place with no clue as to how mods work(not trying to sound ♥♥♥♥-ish, but unfortunately you gotta put in some reading time on how this ♥♥♥♥♥♥ engine works and why modding isn't so cut and dry.)

I have spotted 3 big potential culprits though: PANPC.esm, PACE.esm, and SS2.esm. These 3 mods are script heavy, and loaded together, you're asking for script lag/freezes/and crashes. Sim Settlements is notoriously script heavy, and some advise either staying away, or cautiously playing it with a small amount of basic mods, or dedicating an exclusive playthrough with only sim settlements enabled. PANPC and PACE are also script mods which effect NPC's behavior, and pending the area you're in, an overwhelming amount of NPC's can cause some lag(but i never had any issues personally)

So yeah... you're probably encountering script issues and it's hurting your performance. This is due to the bottleneck that scripts go through which load into your game. An unstable amount can lead to framerate problems, and guess what, scripts are tied to framerate. So your save is more than likely screwed, and you need to cut back on some mods. Try disabling PANPC/PACE and Sim Settlements on a fresh new save.

Also, your mod priorities are whack. You're using a ton of mods that conflict and overwrite each other in odd ways

[Zekiran]

Never download "Collections".

Never ever download and install a single mod without reading all of its bug reports, requirements, and load install / uninstall information.

ONLY ever put one - or maybe two if they specifically state they are compatible - mod on a single 'thing' in a game. Something that affects a single location, or a single item or model, choose ONE, the rest you can live without.

You don't need to pile on SO MANY MODS onto your game. Choose your path more wisely, remove and pare down a LOT of that list, and put them in the CORRECT load order. That will fix a lot of issues but you will also need to start a new save.

[💦Oshawott💦]

Hmm yea i will take that into account next time; I used LOOT as my load order sorter but i guess i have to individually sort stuff out which kinda sucks. had zero clue sim settlements was that much of an issue so i will keep that in mind next time. Mind if u point out the mods which conflict with each other too? surprisingly, no crashes, lag or freezes yet, but that might be because i am still early on in the playthrough

Thanks

for now ive resolved to restarting the game every hour

[Zekiran]

It's literally up to you to do the work, if you downloaded a bunch of stuff, this is what happens... game breaks, because it can't figure out what to put where. What YOU want in your game is what's important here - I know the pain of having to decide not to put x and y in the same game as a and b, because of conflicts, but I'd rather start a new run with each of them rather than have a crashy mess with everything not working at all.

The cpu is the most important component for heavy mod loads, especially the single-thread speed -
https://www.cpubenchmark.net/singleThread.html

The cpu does the computations and the first stages of the graphics pipeline.

The fps drops as the cpu load increases. Big, complex mods like the SS2's need a good cpu not gpu .
Add in a truck load of other junk and you'll bog the game down.

Too many complex scripts.
And as the available script time is limited per frame, scripts get less time as the fps drops and things start to stop working. Spiral descent into chaos.

Full 3D processing is now required because the pre-computed optimized graphics are toast.

Apart from the single-thread speed other cpu attributes are important. Here is a current mid-range cpu. Scroll down to the full test suite results -

https://www.cpubenchmark.net/cpu.php?cpu=Intel+Core+i5-13600&id=5159

Floating point math speed, physics and single thread speed are good indicators of gaming performance.

Note some high fps scores are actually fake from a game engine viewpoint. For example, one technique is to average two frames and insert a 3rd frame in the middle. Sounds great, but the game doesn't perform the computational side. So frame rate improvers aren't necessarily a great thing for Bethesda games. Be wary of cpus with fancy graphics-sounding names producing high scores. When put to a load test they aren't any faster than the same model without the fancy name.

So the answer is - get a better cpu or drop some mods. Because mods compete for a limited amount of resources.

If your gpu isn't running at 100% then it is your cpu.

[VR.IX]

Many of those mods can be reduced drastically, just install GCM from nexus and install previs&pre-combine repair mods.

If you need performance tweak read this, nexusmod mods/49866. based on that article adjust your setting accordingly with your own rigs (enable godray, bokeh etc). I only read those but do not use the provided mods on that article.

Limit your 4k weapon mods or use the 2k ones, dont use combined arms.
For me I use 1 mod type of each weapon, 1 shotgun benelli, 1 sniper rifle accuracy international, 2 rifle(sig mcx and mk18), 1 pistol glock 19x, laser AER15, etc. Your choice.

I use SS2 too, but when Im installing quest mods(depravity, outcast and remnants & project valkyrie) my fo4 became heavier than before. So I uninstall SS2+workshop framework(this is rather heavy too) while completing my latest playthrough with those quest mods. And Im gonna install SS2+workshop framework later, because SS2 is one of mods that frequently have updated episodes.

IMO, the script that running on background is mostly the suspect of 'lags'.

Just 2 cents from my almost 1k hours of fo4 play-through.

[Fumo Bnnuy n Frends]

download some more stability mods. itll fix em

very interesting thanks for the info!! i noticed my cpu (amd ryzen 5 7600x) is at 47% usage. wonder if i have to 'unlock' cpu but idk. thanks for the reply

[💦Oshawott💦]

thank you guys for the supp so far :3

[💦Oshawott💦]

so after a bit of tinkering, i found out how to massively maintain fps despite having a ludicrous amount of scripts.

In buffout, change the os settings:
BSTextureStreamerLocalHeap = false # Replaces the texture streamer's local heap with os allocators
HavokMemorySystem = false # Replaces the havok memory system with os allocators
MemoryManager = false # Replaces the global memory manager with os allocators
SmallBlockAllocator = false # Replaces the small block memory allocators with os allocators

install baka scrapheap and change the toml value to 4.

this is an absolute game changer; however, you should still avoid installing mods with many scripts if you can help it as the fps boost this gives does not last forever. also read ur mod pages carefully to avoid silly little conflicts like the comments above say.
