Fallout 4 PC Performance Thread

I only noticed this now because this is the first time I really started exploring, but using VATS when a target is really far off drops the frame rate to as low as 40 in what is otherwise a game locked to 60

Does this happen to everyone?
 
Full screen trick?
Stutter free game for me required:

1. Disabling ingame vsync in falloutprefs
iPresentInterval=0

2. Enabling exclusive fullscreen mode in falloutprefs
bBorderless=0
bTopMostWindow=0
bMaximizeWindow=0
bFull Screen=1

3. Enable Nvidia Vsync (not adaptive).

4. 60 fps RTSS limit for a bit less mouse input lag.

This is if you can run 60 fps all the time. If you can't, then remove the RTSS limit, or set it to 61, and enable adaptive vsync. If you have gsync then just step 1 and 2 will suffice. Also disable mouse accel in fallout4.ini bMouseAcceleration=0 , it adds a stupid amount of mouse lag.
#2. That is what I did. I actually did all steps minus #4.
 
Just to clarify the 144hz monitor problem..

Is there anything else I need to do other than setting my monitor refresh rate to 120hz to get rid of getting stuck at terminals and speech getting cut in dialogue sections? (ini file tweaks for example)
Thanks

Happens to me too, also when scoping with sniper rifles.
 
Haha once I got to Boston the stable 60 fps I worked and toiled to achieve just gave up. There is so much going on there.

How is Diamond City compared to Lexington in terms of framerate? I can live with the framerate dips in Lexington if the other areas are fine.

Downtown Boston is like Lexington on steroids. If you want a stable frame rate at all times, do your configuring there.

i haven't been to lexington yet but diamond city hits hard. from a pretty stable 60fps to as low as 28fps. i've had to turn a lot of things down and lock my fps to 40. i get close to 60fps when down on the ground but if if go up high like stairs or elevator it will drop to about 45fps.

Getting anything over 60fps can cause problems with terminals and speech. I was running at 100fps and while terminals were okay for me, speech was not. Took out frame cap in .ini file and used adaptive vsync at half refresh rate (of 120hz) seemed to fix all my issues.
 
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.
 
Anyone know how to get the game to not "pause" while the window is not in focus?

I like to play in Windowed mode and multi-task and change music and stuff.

Any option to change this?

You can if you wish, instead of setting your monitors refreshrate to 120hz, set a frame rate limit. Either through AMD Catalyst Control Center, or Riva Tuner for Nvidia.

Setting limit to around 60fps (some say setting to 100fps is enough, but why risk it?) should solve the problem, and you can have 144hz refresh rate still

What is the advantage of doing that vs just setting the refresh rate to 60hz and running borderless fullscreen? That's what I did and there is no vsync input lag and it's smooth. Seems like if you're going to change refresh rate might as well just go down to 60 unless I'm missing something. Which is why I'm asking!
 
After inputting the iFPSClamp=60 line in the .ini I was getting a pretty consistent 60fps in Lexington last night. Had a few small drops to 56fps but they were very quick and far apart. Will probably turn off adaptive v-sync and limit frames with RivaTuner and see if I can get any performance increases.

Just so I can use my monitor refresh rate. I run lightboost at 120hz for all my other games so it is just one thing less that I have to set up and change every time I want to play FO4.

With shadow distance to medium? Or maxed out?
 
That weird texture glitch at the quarry happened to me last night. I just saved, quit, and reloaded and everything was fine.

So far I'm having a great time and smooth performance. i5-3750k and GTX 970.

Okay that makes sense, thank you. I wasn't a fan of the lightboost color degradation so I just normally run 144hz.

Yeah the color changes were hard to adjust to for me but it is hard for me to go back. Hopefully I can get a Gsync monitor soon because I miss my colors.
 
Which FOV you guys with 21:9 monitors are using??

I am trying to reduce the FishEye effect and I cant find the right setting.

Do you have a curved monitor? I'm using 90 fov and I feel the curve on my samsung s34 removes the fish eye effect in pretty much every game. The curve is more pronounced than lg panels.
 
I'm not sure if this has been mentioned before, but holy shit anyone using TAA should seriously consider following this guide or taking similar steps to alleviate the blur that TAA brings. It was legitimately giving me headaches before I changed it.

Got a few hours on it last night but not messed around with the settings too much yet, as it was late and just wanted to play it.

The game auto detect gave me the High Preset, with Ultra Textures and God Rays: High. So I turned God Rays down to low, dropped the distance down a little on character fade and object fade, turned off motion blur and I'm getting between 50 - 60fps most of the time, with the odd, random dip into the 40's but it never stays that low for more than a few seconds, maybe a loading / streaming bug, who knows with Bethesda.

Loving the game though, it's basically Fallout 3 but a newer, better looking version and that's fine with me. I guess because it's been a long time and they haven't milked it to death every year, that it still feels fresh enough to feel special, at least for me anyway.

I have a flat 29" LG 29UM67.
I am also using 90 FOV. I wonder if there is any other setting that can reduce Fisheye.
 
So is borderless window really actually helping some people? I have yet to try it, but from the anecdotal evidence in this thread, it appears to be helping.

I'm going back to Lexington when I get home to really try to figure out what the fuck is the problem. For me, 60FPS solid is more important than anything else, so I am going to try and make it happen. Does turning off motion blur help at all? I can't even notice any motion blur to begin with.

I wish there was an option to automatically drop settings upon entering a city, so that we wouldn't have to give up our ultra settings outside of the city.

Yup
 
Change the res settings manually in the .ini file, they're just above bBorderless etc.
Don't go back into the video setting when you restart the game or it resets it.

Is it the Fallout4.ini or FalloutPrefs.ini? And the one in user folder or Steam Library? Thanks in advance!
 
Guys, im pretty sure the problem with the framerate in citys has to do with the shadows. The game doesnt have very good occlusion culling like the witcher does ( witcher uses umbra framework )

So when youre in the city, if youre looking at a wall, the game is still rendering everything beyond that, even the shadows, even though you cant see it. and when you have shadow distance on high, it renders shadows for the ENTIRE city at all times. It doesnt occlude anything. Turning shadow distance to medium makes shadows really only appear when youre close enough. But ive notices that on medium it still looks phenominal and you dont really notice it all that much.

So if youre having trouble with fps in lexington and diamond city etc, turn shadow distance to medium, it fixed everything for me.
 
Performance in any major town/city is rough. Gonna try some more changes but right now it feels like it's just an inherent thing.

Thanks for the info. I'll give it a try tonight when I get home. Any pic comparisons of shadow settings, by chance? I would love to see the differences between Low all the way to Ultra.

I actually just tried this again for a second time, and it.. seems to work this time? :D

Use a third party tool like radeonpro or rivatuner to set an fps limit of 110. Anything higher shit starts to go wrong such as terminals.

The jump in units on shadows in the ini file from med to high is huge in units, medium is 3000, high is 14000. That's just over 4 times! This guy here has images and ini tweaks:

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.

So far I'm having a great time and smooth performance. i5-3750k and GTX 970.

Funny, I encountered that exact same one yesterday. Restarted and it was fine from there. Loving the game. After playing for 6 hours I just hit Diamond City following some advice to power through the game to get to that point. I'm getting an almost steady 60 FPS with minor dips to mid 50s there. Not even a factor for me. If it helps anyone I have:

i5 2500k @ 4.4 (Seriously, this processor keeps on chugging along. Best one I've ever purchased.)
2GB GTX 960
8GB RAM.

My settings are:
Texture Quality: High
Both Shadows: High
Decals and Lighting: Ultra
Godrays: Med (and considering Low since I don't see a friggin major difference in any of the settings.)
SSAO
Everything else is checked on the bottom.
View Distance sliders are all maxed out.

Do you actually think this is something Bethesda could improve in a patch or is it likely we're stuck with non-existent shadow culling?

The distance or the iDirShadowSplits would be more CPU dependent? I was thinking about customizing my ini file, I have a 3570k though, not an AMD cpu.
 
i'm not sure if this is just because of my player or a bug. bullets never seem to hit where i aim. maybe i just need to level up a certain perk? or is this an issue with the game? it seems to be more accurate when aiming down sights instead of using the little dot.

I'm sure they could improve it (any complex software can generally be improved).

But it will never be cheap to render accurate shadows for a large number of dynamic objects (and that's where distance comes into play: the larger the distance the larger the number of objects).

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

It would only make sense for 1 light source though (sun!)
 
Is this thread appropriate to post a help request in? I'm experiencing some weird stuff when trying to boot the game.
