Fallout 4 PC Performance Thread

I love the Computerbase article on the game's technology, because it shows once more how silly people on the internet are when it comes to looking for things to get outraged about and/or conspiracies.

Supposition 1: Nvidia Gameworks features are designed to make the game run badly on AMD. Evil Nvidia!
Fact 1: Ultra godrays have a 34% performance impact on a 980ti and a 28% performance impact on a Fury X.

Supposition 2: The console version CPU limitations are due to Bethesda not parallelizing their engine. Lazy Bethesda!
Fact 2: (This is a direct translation of the CB article) "The game seems well optimized for all CPU features. Regardless of whether it's more frequency, more cores or Hyperthreading, everything improves performance. You rarely see such good scaling."

(You can replace "Supposition" with "Tales from my ass")

Do you think 1 global ray trace done for shadows would improve that?

It would only make sense for 1 light source though (sun!)
I'm not sure. UE4 can do something similar to that, but I don't know how much precomputed information it uses.
 
Just know that any advice that tells you to adjust iFPSclamp is always wrong.
Someone added the advice to put it at 61 on pcgamingwiki.

Just don't.
So you driveby to say a potential fix for some people that has been working is always wrong yet you dont offer any alternative. Nice.
 
I'm mostly very happy with performance on my rig but I've had to settle for lowering some settings in order to hit a completely locked 60fps (at least, during the first few hours).

Game isn't as ugly as I was anticipating but it's not impressive either. The TAA is quite good, though, I'm surprised.

We'll see how it holds up in a larger city.

I don't think TAA is that heavy. I'd say it's the best AA out of games I've played recently. GTA V was terrible, The Witcher 3 was good but still noticeably jaggy. Fallout 4 looks really smooth. The only thing that looks a little jaggy is any wires. Really happy with it even while in the largest city in the game.
 
I'm a bit busy right now and can't comb through the thread so if anyone can give me an answer I'd appreciate it.

How's the port? Anyone with 8GB RAM, GTX 980 and Win 10 that can report? What's performance like at 1080p?

About 4 hours in and smooth as smooth can be so far, running a 980 and i7. 60 locked.
 
The aliasing is getting just a tad bit annoying. Hoping we get Crossfireprofiles soon enough, so I can supersample and still hold 60fps.

But no word from AMD yet about Fallout 4 specific betadrivers :(
 
What's with the game running at 30 ~ 40 fps outside but indoors it tanks to like low 20s?

I'm running on medium everything, with godrays off, FXAA, and depth of field at low at native 1366x768 fullscreen.

Playing on my laptop which is a y510p lenovo, not the beefest of laptops anymore but it handles most games just fine due to the low res. I don't have the game ready drivers yet if that makes a difference.

Game handles perfeclty fine except for certain indoor environments (the ones you have to load into), it's not all of them either, I suspect it has to do with the ones that have more of the foggy type ambiance going on. Like for example the Police Station in Cambridge runs normally but the bowling alley in the gallery runs at like 14fps average.

Notably the power plant by Lexington also tanked my FPS, thank god for VATS.
 
I'm not surprised that the OP in that reddit thread is using an AMD CPU and GPU. Shadow rendering in a game like this where you can't precompute visibility is probably very CPU intensive. That's likely why the consoles are stuck at anemic shadow distances.

I'm using a modest i5 3570k@4.5GHz and high shadow distance completely kills my fps in cities. It's not maxing the CPU by any means, in fact there doesn't seem to be any difference in CPU usage between medium and high shadows. Not a single core goes above 80% usage. It feels more like a bug (with the game engine?) than a simple performance issue at this point. But we'll see if Bethesda responds to performance issues at some point. Obviously console versions suffer even more than most PC setups.
 
I know many, many other people in here have already said it, but FPS is just so weirdly inconsistent in this game. I'll be running along at 60+ frames, and then randomly drop down to the low 40's for seemingly no reason at all. Or I'll turn the camera slightly to look at something and bam. 15-20 FPS loss. Really weird.
 
Anyone able to comment how the game runs on a 7950 with windows 10 and 8gb of ram?

I'm on Win 8.1 and my processor is an i2500K OC'd to 4.5GHz; same RAM and GPU.

I'm running everything on High @ 1080p except for God Rays, Shadow Distance, and Shadow Detail. I haven't done any benchmarking, but so far the performance has been smooth except for one interior area where FPS definitely dips significantly (high teens, low 20s). I've yet to perform any optimization and I will try running full screen later today to see if there's any difference.

The game looks great and I've yet to run into anything I'd call "unplayable". Granted, I'm still very early in and haven't reached areas where most have reported framerate hits, so take this with a grain of salt.

Near solid 60FPS at all ultra (minus high God rays) with some dips into the high 50s when entering new areas for the first time (likely a streaming issues despite the fact that I'm running off an SSD). No stuttering either. Haven't got to the major cities though, just the few small towns in the first area.

The opening looks GOD AWFUL by the way. What a poor way to show off the game. Once you get out of the vault and into the real world, it actually looks acceptable for a 2015 release. Like, not great but certainly good enough (minus the animations, especially the lip syncing). Characters still look atrocious with no subsurface scattering or any other bells and whistles and are super low poly. But the world looks shockingly nice. It's a weird mix.
 
Anyone able to comment how the game runs on a 7950 with windows 10 and 8gb of ram?

I can hold 60fps @ 1440p with most setting on ultra except godrays on low and shadows on medium. Lowered the draw distances a bit. I get some dips on occasion. I'll do more tweaking tonight and post my settings.
 
I was surprised turning godrays from high to medium and shadows from ultra to medium did absolutely zero for my framerate in Lexington.

2500k
7950
8gb ddr3 1600

almost solid 60fps, saw it dip down to 47 when running to the vault. i forced vsync off in amd's ccc, but it remains on in game. dunno how high my fps goes. any other way to force vsync off?


1080p
FXAA
AF x16
texture quality high
shadow quality med
shadow distance med
decal high
lighting high
godrays low
depth of field bokeh
AO off

all extra boxes checked

view distance was left alone
distant object detail med
object detail fade med


Edit:bumped the high settings up to ultra and fought the death claw, no dips. Interesting.

after removing the fps cap, i saw highs of 80-90 while in the commonwealth. however at the car plant saw dips down into the 40s. im about 8 hours in now and thats the worst ive seen. it seems like ive got plenty of headroom to increase more settings. im quite pleased, 7950 still goin!
 
Anyone with an older Intel CPU like Nehalem or Sandy Bridge playing this?
How is it performing when you're in areas densely populated with buildings and geometry?

My old i7 920 @ 3.8 is struggling a lot in some of the really dense areas like the one near the start of the game where you take out all the raiders that has all the metal walkways and platforms. (Corvega Assembly Plant)

Seems pretty solid, alright, thanks guys.

I'm playing on a 4.0 930. I got a lot of jank from Corvega Assemply plant, but only observed ~%40 cpu usage. For shits and giggles, I changed my graphics settings to low and still got stutter there. Running a 770 btw.

From what I can tell, the occasional jank is going to happen regardless. Best I can do is optimize for the times jank won't occur. I'm sitting on mostly high settings with that in mind. Borderless windowed helps alleviate a lot of stutter.

Are you holding that in places like Lexington or Diamond City? If you are, I'd be pretty amazed.

Wonder if I should DSR this one now that shadows on Medium seems to help a lot..
 
I5 4670k @ 4.0ghz
16gb DDR3
GTX 680 2gb SLI

Forced SLI in the control panel, running the high preset with godrays on medium. The lowest fps drop i've seen was from 60fps to 55fps in
Concord at the plant for the minute men quest. Standing on the outside catwalks made me drop from locked 60 to around 55ish
. Everywhere else it's been locked to 60 constant. Inside, outside, during combat, doesn't matter. I haven't gotten to diamond city yet, but i've been doing some of the
brotherhood of steel quests from the police station
which is a more populated area and I haven't seen any drops at all.

getting about 60-70% gpu usage on each GPU, really looking forward to an official profile though.
 
AMD FX8350 black @ 4.2
R9-290X not overstocked
8 gig ram
Win 10

Game has everything set to max at 1080p with God rays on low. Getting a locked 60fps.

No crashes or stuttering but only a couple of hours in so far.

I'm on my i7 860 (@ 3.6GHz) with a GTX 680 (2gb), SSD, 8 gb ram playing at 1080 and the steam fps counter has been pretty steady at 60fps. I let the initial setup decide the settings which it suggested high. I had my doubts but it's been great. I was completely expecting to be in the 30's or so. I have noticed a little microstuttering going on from time to time even though the framerates telling me 60ish but other than that no problems. Haven't played with the settings at all because I've been too into playing so I'm not exactly sure what settings are turned to what outside of the high preset.

EDIT: save says ~7 hours, been staying around the beginning areas so far though so maybe once i get to more densely populated areas it'll take a dive.
 
How do I get the FOV to stick?

I edit the three ini files as described in the guides. I load the game, the FOV is not what I set.

I open the console type fov 90 or fov 110. The game sets that FOV, then when I close the console it zooms in again.

Am I missing something?

Try setting those files to read-only mode after you've modified them?
 
So overclock3d.net just benched the 980 Ti at 142 fps average and 109 fps minimum (1080p ultra) while my 980 Ti drops into 30 fps and is nowhere near 142 as maximum fps... Wtf.

Has anyone tried changing ini settings? Specifically changing the LODs distance of vegetation and messing around with Ugrids. Do they still cause glitches or save file corruption?

They probably didn't benchmark the game in bad fps places.
 
Code:
i7 4790k - GTX 980Ti SLI Off 358.91 - 16Gb - SSD
GodRays Medium - Rest on ultra - 1080p@60fps locked +/- 50% GPU Usage
No performance problem encoutered thus far (12hr+ played), but a lot of textures/meshes glitch.


Happened a lot of times in different places, the worst was on a bridge. I thought it was just a low textures bugs, but then I fell through, and died, without saving since a quite good amount of time.

Skyrim had the same problem for me.

Had the same issue in the same place

You can't be surprised unless you are using numbers on the same sequence, Fallout 4 does not perform equally in every area, like any other AAA game.
 
Game is pretty inconsistent on my rig. Mostly it's 70+ fps but places like Lexington can make it go down to 20-30 when looking at certain specific directions. Some weathereffects like mist also brings it down to low 50s.
I got most things on ultra except godrays.

Sorry if it's a dumb question but I was wondering what the minimum requirement were referring to in terms of resolution and framerate.

I have a GTX 660m (Yes I know laptop) but only 6 GB of Ram and an i7-3630QM @ 2,40GHz.

I was thinking to low at 720p@30fps might be doable, what do you guys think?

Sorry if it's not really thread related.
