Fallout 4 PC Performance Thread

The subtitles are bugged regardless of your settings. I have watched a few streams and the subtitles are messed up in a lot of areas. By fps lock you mean with iPresetInterval=0 + driver vsync or RTSS?
Ya Catalyst CP and iPresetInterval. The subtitle issue stopped after that revert, for now D:
 
What is the default FOV value? i was messing around with that till my eyes started to tear, now i want the default value again, somebody?

Didn't see any change. Still stutters.

Those with a 970 or higher, and getting bad drops... please consider trying this tweak. It worked for me and I am holding 60 even all through Lexington and the power plant.

also use default FOV of 80, as it seems raising it really affects performance.

Tried them out, and it feels the same. Unless fov 80 really does make a big difference.
 
Has there been an explanation why on some systems borderless window runs the game a lot smoother than the default fullscreen?

Makes absolutely no sense to me why this is happening, but now I've found a really easy way to show why the so called 60fps doesn't feel like it at all, and it's all jittery.

I can go to pretty much any area that has a stationary "go here" mark and strafe left and right facing it. It should stay stationary right? For me it doesn't. Strafing causes it to do what looks like a super exaggerating flicker/ghosting effect as though there's some strange interlacing of frames (as though it's 30fps x 2) is happening. The entire game runs this way.

Of course, switching to borderless windowed mode fixes this, and it's a solid 60fps without it feeling like a sloppy 30fps. I even disabled vsync to see if that was the cause, and it's not.

Yup, same experience. Strafing left or right while look at a texture is the easiest way to tell. This shit is in fallout 3 and NV as well. Lessened with mods of course. Gamebryo never changes.

Rivatuner doesn't even want to work with the game either. Doesn't matter if I set it up for the Fallout4.exe or Fallout4Launcher.exe either.
Also, I don't know that it's just a Gamebryo thing. Morrowind, Oblivion, Skyrim, Fallout 3 and Fallout:NV do not do this. They all run without issues for me.
 
This seems to have introduced some screen tearing for me.

You sure you enabled non adaptive standard vsync in the nvidia control panel? A 60 fps rtss lock + adaptive causes screen tearing, standard won't. Use standard vsync or remove the rtss limit for adaptive. Also make sure your .ini settings have stuck, some revert if you open the settings menu in the launcher.

What are you having RTSS point to for the profile? It doesn't even detect the game for me, or at the very least it doesn't feel like it's doing anything in the game, and the fps overlay isn't showing up. RTSS works fine with the other games I've used it with.
In borderless windows, Fraps doesn't actually appear to be working correctly either. It stays stuck at 62fps, even though my screen is 60hz, and it never fluctuates, even in areas where you can tell there is a difference. When running in fullscreen however, Fraps works like it normally does.

I've set mine to global since I play all games with 60 fps limit + standard nvidia vsync. Try that and try resetting rtss global profile to default, but just targeting fallout4.exe should work. Works in both fullscreen and borderless windowed.
 
man this game sucks in terms of optimization

i have a 765m with a mobile i7. for refrence, maxing out MGSV at 900p gave me 30 fps with drops. Keeping in mind that MGSV looks like MGSV and Fallout 4 looks like Fallout 4, assuming that maxing out FO4 would end up with basically a locked 900p30, maybe with dips, right?

WRONG

disabling v-sync using the ini file and using RivaTuner locking the fps at 30, even at medium preset and then going into advanced and still dialing some stuff back, it's basically sometimes 30 with lots of drops.

like even shadow of mordor arguably looked nicer than this and it ran (slightly) better at higher settings.
 
Can someone please see if this simple 21:9 fix actually works?




Have you tried adding `-CustomResolution:enabled -r3440x1440x32` to your launch options? It runs at 3440x1440 with no HUD problems for me.

http://www.reddit.com/r/ultrawidema...allout_4_ultrawide_support_review_waf/cwx8xyf

Doesn't work for me in both borderless or fullscreen. Maybe this guy has monitor scaling turned on and it's stretching 2560x1440 to fill the screen. His screens look a bit stretched.
 
Is there any setting that could possibly make subtitles bigger? They're a little hard tor read since there's nothing dark behind them to make them stand out.
 
Running pretty smoothly now, the 60fps frame rate limit has helped quite a bit, as I haven't been stuck at any terminals since, and no real noticeable stuttering.

Though yesterday, at least on one occasion, I got the dialog bug (dialog being cut before it finishes, and lipsync going out the window), so I don't think that's related to the "speedbug" or too high of a frame rate. Seems to be a bug with the engine.
Only ini tweaks I've done are mouse and FoV related.

Anyone with the same setup? How's the performance?

Running the same GPU but with Core i7 6700k. Getting pretty steady 60fps (frame rate locked in Catalyst control center) @ 1080p, with God rays on low, shadow distance on medium, rest on ultra.
 
So it seems physics are only tied to the framerate when you're not using v-sync?

144fps v-sync looks normal to me. Unlocked and everything breaks.
 
So I have a 970 FTW+ and an i7 3770k. Had the game at everything maxed out, 1080p. Ran great aside from weird framerate jittering in certain spots. Problem is, when it happened, it was really bad.

Unlocked the framerate in the FalloutPrefs config file and then turned both Godrays and Shadow quality to high instead of ultra. Game runs flawlessly now. Figured I'd share in case anyone else had the same problem.
 
I'm getting stuck on loading screen now, tried multiple saves and none of them work. Googled around and people on reddit are having the problem also. Anyone else? I really hope I don't have to re-do 7 hours of gameplay =/

Going to try verifying cache, if that doesn't work will uninstall then reinstall I guess since there's no other choice that really sucks though if it comes to that.

edit - verifying cache seems to have fixed it for now, gonna backup my saves after every session just in case.
 
A friend of mine keeps getting super weird graphical glitches while he's playing, apparantly happens randomly after an hour or two of play. Anyone got any ideas? He doesn't want to redownload the game for obvious reasons.

Does he OC anything? Looks like GPU Memory corruption.

The physics and game speed is tied to the ini tweak iFPSClamp I think, if you change that, it can break the engine.
 
Well, Lexington it's a mess on my 970 @ 1080 Ultra(God rays low), 50-60 fps but a hell lot of stutter and jitter. Adaptive vsync feels smoother in that section of the game but man the input lag it's horrible. I'll try lowering shadow quality

Have you tried borderless windowed mode? There are points in the game where running it in fullscreen feels buttery smooth, but then as soon as I enter a hallway of all places, it feels like the framrate is cut in half, even though it still shows 60fps. In borderless windowed though, that issue doesn't happen at all. I can't explain it.

On my GTX 780, I noticed the profile was set for multi display by default (clean install), and I wondered if that was the cause of this problem, but it's not. Setting it up for single display and performance doesn't change anything for me.

I ran borderless windowed mode on my 970 just now and had noticeable performance drop from 60 to an unstable 40-50 in Sanctuary

Is there something else you need to do when enabling borderless?
 
I can't play in windowed at all on my 980 ti. It just limits my fps to 30-40 no matter what other visual changes I make :s. Fullscreen works though (kind of). I also have the problem where certain areas (mostly towns) like Lexington just takes a dump on my fps, going from 85 to 30ish.

Are there any good ways to limit fps in the ini or is changing ur screen hz in display properties still the best way to go?
 
Lots of CTDs for me. Pretty random.

I'm getting crashes too probably around 1 an hour. Game hangs, goes to desktop and the music keeps playing. Only thing I can do is kill it in task manager.

Have you tried running it in a boarderless window? I'm going to try that this evening.
 
Is there any solution to the random drops of GPU usage even when the frame cap isn't being reached?
It can't possibly be a case of CPU bottlenecking, I have a 3930k @4.8Ghz...

This made Lexington go from 30-85 to 60-85. Very nice!

Edit: Hmm, really weird. Tried removing the setting and I still get 60-85 fps in Lexington. I definetly never got that good fps before the ini tweaking though so dunno what's changed.

Download and use Riva Tuner Statistics Server to limit to 60 fps. As a side benefit RTSS is generally pretty decent at helping with frame pacing I believe.

Personally I have CPU usage drops. Not randomly, but every time I use a scope.
Irritating because 90% of the time I run the game at 60fps through a cap. In Lexington I got a minimum of 40fps, but it remained very smooth and responsive. Average in Lexington was 60fps. This is while running it on Ultra including godrays at 1080p.

To this point I was pleased. Until I tried using a scope. This literally cuts my framerate in half or lower. As soon as I use a scope in certain areas in any case the cpu usage drops from about 50% to 24%.

Tried lowering my settings in every aspect, but while using a scope this does not help.
Thought it could have something to do with heavy foliage and a lot of transparency, but the same thing can happen even if I look at en empty hill with one bush on it.

What else? In one area where the framerate drops to let's say 40 it remains smooth and responsive. In another where it drops to the same value it feels like it's running below 20.

Latest drivers.

EDIT:
Ok. For me disabling the in-game V-sync by setting iPresentInterval to 0 (fallout4.ini in "My Documents/My Games/Fallout4")and forcing it through Nvidia's drivers gave me a 5fps higher minimum while using the scope.
Setting Godrays to "low" gives me 52fps as a minimum while using the scope. Unoptimized godrays much?

EDIT 2:
Godrays set to off = 72fps minimum while using a scope. Everything else is on Ultra.
For the godrays to turn off I had to click the "low preset" setting in the launcher and then max the other settings individually.
 
okay, I don't know if this is the right place to ask, but I'm going to ask anyway. okay so I finally got the game up and running after installing the latest drivers and unpacking it. after skipping threw everything to see how the game runs, I then went to disable vsync (I have a Gsync monitor so no need for it) then I went back into the game to see if I gain any performance, I gain abit more fps but not that much. anyway my problem is that I'm stuck in first person. and before I switch off vsync in the ini, it was fine. so I went back and switch vsync on thinking it was turning causing the problem. but alas I can't go into 3rd person. so yeah any idea on how do fix this???
 
For me, it broke g-sync as detailed above. Rolled back to older driver and have no problems.

Thanks for this. Will be rolling back when I get home. Finally got the game running at a "smooth" 60 fps 95% of the time, but as soon as there's a drop it gets jumpy as fuck, suggesting that gsync is not working as intended.

I tried borderless windowed mode, too much stutter in my case. Fullscreen without vsync and framerate fixed at 60 it's the best option at the moment.

Thanks, Pagan! Is this CPU or GPU game? I can OC my i5 if it's needed.
 
Has this helped anyone? Found it in that Reddit thread. Got my game running 99% buttery smooth, but I'm still getting a few hitches here and there running across the map.

According to this comment and all the other posts it links to, this setting shouldn't do anyting at all for in-game performance.

Is it possible that behavior changed in Fallout 4 from Skyrim, however? I see mention of VMMap which might be one way to test it.

It might also be possible to benchmark a very specifiic location -- low framerate vs. high framerate changing only that parameter to see if it really makes a difference.
 
290 does fine thoguh the AMD driver is pretty CPU limited from the data DF put out.

It would have dips into the high 30s in some areas due to CPU driver problems.

what does this mean? i have a 290 and had drops to 30's in Diamond City. is the CPU being over/under used or something? can i get a link to the DF article.
