Hi !

So i have a r9 290 and fx 8350 and 8gb of ram but i am getting about 24 fps in the game with the game at ultra with godrays at medium.
i am running at 2560x1080 and i am experiencing no spikes but a constant 24 fps which is way to low for these specs, but is this a cpu issue or a AMD optimization problem? since a r9 290 should not have 24 fps with dips to 19 in fallout 4....

 
Solution


Oke just fixed it by setting my hyperthreaded cores in the .ini file to 8
it was on 4 but my cpu has 8 cores.
this resulted in my cpu going far higher and my gpu always at 99% instead of 20%


Yeah, finally got local leader perk. Now i can make trade and the attacker starting to roam like crazy. I have fun when I was there to defend, but mostly i missed them. I love stripping the attacker for parts XD
 
Just adding my $0.02 to the internet.

I've been getting sudden drops in fps on my GTX 780.
It would hit 20-30 fps even though I get the full 60 fps moments before on the same scene.
It usually happens after a quick load.
I'd have to reset my computer to resolve the issue, but it happens again after a few minutes.
I don't overclock, I have no mods, and I have 16 GB of RAM.
I resolved the issue by swapping in an R9 290 from my other rig.
The other rig runs perfectly with the GTX 780.
The two cards are about equal in performance, although it seems like the GTX 780 gives more stable fps due to less CPU utilization.

On another note, this report states that RAM speed affects fps.

I can verify that because I accidentally downclocked my RAM to 1333 MHz during a BIOS reset and got horrible fps.
I realized what I did and reclocked my ram to a full 2133 MHz and it resolved the issue.

i5-2500K @ 4.8 GHz
 


Interesting. I still don't get good performance. (at least to my standards. If I can max witcher 3 i should max this game.) I have an r9 290 with an amd fx-8320@4.3 ghz. This leads me to believe that the CPU is the issue even though the usage rarely runs past 50 percent.

The memory part is interesting because I read an article about memory having a major impact on the games performance and I am wondering if my performance isn't adequate because of it. I have memory at 1866mhz but IT IS SINGLE CHANNEL. I am going to try and upgrade the memory to at least dual channel 1866mhz. However I heard that the AMD gets little benefit from OCed ram on Fallout 4. Maybe Intel just has a stronger memory controller?

 
According to this review:
http://www.techspot.com/review/1089-fallout-4-benchmarks/
AMD CPUs are being outperformed by i3s. So you may not be able to run @ full 60fps on Ultra. Surprisingly the game scales very well with memory speed and i7s, which could mean hyperthreading or cache sizes.

Having dual channel might help you out in this case! But even an R9 290 is having trouble running @ 60 fps.

 


Ya regardless I feel pretty cheated about the performance I am getting. I see people with worse specs playing with the same or better fps. These people have computers that could only dream of playing Witcher 3 on ultra 60fps. It is a good game but their programmers are really incompetent and should be replaced. Just my 2 cents.
 
Where do you see ppl with worse hardware getting more performance??
I know a guy having a 980 ti+i7-4770k oc+8gb ram he is playing most games in 1440p except fallout 4 he plays on high-ish (not max) and 1080p bcs he is only getting the performance he likes when doing so

Im interested in what inferior hardware could run the game better than yours??
 


I wouldn't say better performance but mostly the same. There are many examples I've seen of gpu's equivalent to a 270x and i3 cpus running with very very similar results. It seems as if there are many reasons for this. Memory, Software, Game engine, etc. I've noticed the game is utilizing about half of my cpu and gpu. I believe it is either because I have an amd cpu or inferior memory but it seems to be related to the optimization too.

 


i have an i7 4790k r9 290x and on high i get ~40fps with cpu usage at around 35% and gpu usage that drops to 0... With a radeon hd 7870 on medium i am getting constant 60fps and on high about 35
game really is poorly optimized
 


sorry, i'm not very active recently on the forum.
its located in the C:\Users\<yourname>\Documents\my games\Fallout4 and then the fallout4.ini file in there the iNumHWThreads should be there if not add it to the general section. the iNumHWThreads should be the same as the total thread count of your cpu so a fx 8350 has 8 cores but no hyperthreading so it has 8 threads and a i7 4960k has 4 cores but has hyperthreading so do the core count times 2 and it has 8 threads.

so the core count of cpu and if your cpu has hyperthreading do your core count times 2.

 


I don't have iNumHWThreads in Fallout4.ini.... wtf?.... all i have is this

bMultiThreadedAccumulation=1
bMultiThreadedRenderingUNP=1
 
Change to windowed borderless instead of full screen. I was stuck at constant 30 fps and I changed and BAM instant 60 lol we arr never gonna get rid of this bug on bethesda games quotemsg=16930737,0,1766015]


nope still 24 fps @ low 1080p and vsync off[/quotemsg]

I'm having pretty similar issues to many here. AMD FX 8350 4.0GHz, 16gb ram, R9 280x OC. Stable 50-60 in almost all indoor areas, and most open (not city) outdoor areas. However, once I hit certain, more built up player settlements, and much of the downtown Boston area, I get horrific drops down into the low 20s and sometimes even lower. I opened a similar thread and got directed to a benchmarking test which indicated that AMD CPUs overall, do not play well with Fallout 4. Very sad times indeed...

I turned both of those up to 8 and have been achieving a stable 50 fps but still only utilizing around 40% of my gpu however its a step in the right direction from utilizing almost nothing.

 


Gentlemen,

I've been observing poor fps on my system with FO4 too. Naturally I started OC'ing the components:
1. GTX 970 to 1500 mhz/1.1v GPU,
2. i7 3770k to 4.6Ghz/1.3v and,
3. DDR3 8GB 1600mhz RAM to 2200mhz/10-11-10-26/1.65V.

The poor framerate problem was immediately relieved when I applied the RAM OC.
Then I found this: http://wccftech.com/fallout-4-performance-heavily-influenced-by-ram-speed-according-to-report/

Thought it might help you guys
 


Might help ill check it out since I have 1333 MHz ram
 


hey i had this very same issue people told me to look for cpu overheating and everything i found nothing wrong it later turned out to me my screen it sounds crazy but it worked for me my monitor was 1280*1024 75Hz cpu amd 8320 gpu r9 380 4gb yet i was getting 24fps on all settings i tried from low to high i pinched my sisters tv which was 1920*1080 60hz and for some reason fps issues were gone from fallout 4 and some other games i later bought a new monitor and have had no issue since ........note i have turned v-sync off in fallout 4 ini file and used a frame rate limiter to 60fps im running the game on high even with god rays on and im never dipping below 49fps average is 55 fps and 60fps most the time
